Unlocking the Invisible

Inside the UW School of Pharmacy’s Mass Spectrometry Center

When Dale Whittington arrived at the University of Washington, he did not imagine that he would one day help shape one of the School of Pharmacy’s most consequential research facilities. Trained as a biologist, with a career path that briefly veered away from science altogether, Whittington eventually found his way back—drawn by the chance to work at the intersection of discovery, teaching, and problem-solving.

More than a decade later, as technical director and manager of the UW School of Pharmacy’s Mass Spectrometry Center, he oversees an operation that quietly underpins a wide range of scientific work. It is not a space defined by spectacle, but by precision: instruments that weigh molecules with extraordinary accuracy, revealing details that would otherwise remain invisible.

At its core, mass spectrometry rests on a deceptively simple principle. Molecules are given an electrical charge and guided through electromagnetic fields toward a detector. How they move—and how long they take to arrive—reveals their identity, structure, and abundance. From this information, researchers can determine molecular weights, concentrations, and subtle chemical differences that shape how drugs behave in the body.

From small molecules like amino acids to complex proteins and antibodies, mass spectrometry has become a foundational tool across chemistry, biology, and medicine. Its reach is broad, but its value lies in specificity.

From Molecules to Meaning

The real power of mass spectrometry emerges not from the instrument itself, but from the questions it allows scientists to ask. Researchers use it to track how medications are absorbed, distributed, and eliminated; to study how proteins change in disease; and to understand why a therapy may work well in one context but fail in another.

“This is the tool that lets us interrogate biological and chemical questions at a fundamental level,” Whittington says. “Whether you’re studying drug concentrations in tissue or changes in proteins during disease, mass spectrometry gives you a way to see what’s actually happening.”

For Mary Hebert, a professor of pharmacy and director of the UW’s Obstetric-Fetal Pharmacology Research Unit, the Center’s work is essential to understanding how medications behave during pregnancy and lactation—populations historically underrepresented in clinical research.

“The pharmacokinetics of most medications have not been studied in these populations,” she explains. “The Mass Spectrometry Center has made it possible to identify not only how drug handling changes during pregnancy, but also allows us to make informed predictions about other medications eliminated via similar pathways.”

Learning by Doing

What distinguishes the UW School of Pharmacy’s Mass Spectrometry Center is not only its technical capacity, but its approach to training. At many institutions, mass spectrometers are operated exclusively by specialists, with users receiving only processed data. At UW, students are encouraged to engage directly with the instruments themselves.

“Our goal is to train mass spectrometrists, not just data recipients,” Whittington says. “Students learn how to prepare samples, optimize methods, troubleshoot problems, and design experiments from start to finish.”

Graduate students progress quickly from observation to hands-on work. By their third session, many are expected to operate independently, with staff stepping in only when needed. The experience demystifies the technology—and builds confidence.

That experience carries weight beyond the university. Graduates trained at the Center enter industry and academic labs able to operate instruments, interpret results, and adapt methods with minimal supervision. Employers recognize the difference.

Medicinal Chemistry Affiliate Assistant Professor Kim Alonge, whose research focuses on the brain’s extracellular matrix, sees that impact firsthand in her trainees. “Direct access to mass spectrometry empowers them to generate and interpret complex datasets independently,” she says. “That accelerates their development as scientists and makes them more competitive for fellowships and careers.”

Expanding the Boundaries

While pharmaceutical research remains central to the Center’s mission, its applications extend far beyond drug development. Mass spectrometry has been used to analyze compounds in cannabis products, verify the composition of fish oil supplements, and even fingerprint wines to confirm their geographic origins.

One rapidly advancing area is MALDI imaging, a technique that allows researchers to map the spatial distribution of molecules within thin slices of tissue. The sample remains intact, preserving information about where compounds accumulate—or fail to reach.

This approach has reshaped understanding of HIV therapies by revealing uneven drug penetration in tissues, helping explain how viral reservoirs persist despite treatment. In neuroscience, it is opening new windows into the chemistry of the brain.

Using the Bruker timsTOF fleX platform, the only open access MALDI (matrix assisted laser desorption ionization) tissue imaging mass spectrometry in the northwest, UW students and researchers working with Alonge have mapped glycans in the hippocampus, uncovering spatial patterns linked to Alzheimer’s disease. “Without access to this facility—and this specific technology—those insights would not have been possible,” she says.

Looking ahead, Whittington sees artificial intelligence playing a growing role in managing the sheer volume of data mass spectrometry generates. “There’s more information than any one person can reasonably process,” he notes. “If we can apply AI in a careful, unbiased way, it may reveal patterns we’re not yet able to see.”

A Place to Grow

For Whittington, the appeal of the Center lies in its constant motion. Each project presents a new puzzle; each student brings a different way of thinking. The work resists routine.

“I feel fortunate to do something that’s always changing,” he says. “Between the teaching, the experiments, and the problem-solving, no two days are the same.”

For students and researchers alike, the Mass Spectrometry Center is more than a shared resource. It is a place where theory meets practice, where complex tools become accessible, and where careful measurement leads to clearer understanding.

As Hebert puts it, “There are critical questions—especially in pregnancy—that simply can’t be answered without highly sensitive, specific assays. Without this Center, we would not be able to quantify drug exposures that matter for both mother and child.”

In a field often defined by what cannot yet be seen, the Mass Spectrometry Center helps bring the invisible into focus—one molecule at a time.

 

Short Cut: What Does a Mass Spectrometer Do?

  • A mass spectrometer is a scientific instrument that can be used to identify and measures molecules by their mass to charge ratio. It works by giving molecules an electrical charge and guiding them through electric or magnetic fields to elicit an electrical response on a detector. Because mass spectrometers can manipulate the transmission of molecules through electrical fields, the instrument can be used to determine what substances are present and ultimately help calculate much of each one there is. Scientists use mass spectrometers to study everything from how drugs move through the body, to how proteins change in disease, to where specific compounds are located within tissues. In short, mass spectrometry allows researchers to detect and measure chemicals with extraordinary specification and precision—often at levels far too small to see by any other method.

Everyday Cleaners, Everyday Exposure: Disinfectants’ Impact on Human Health

Disinfecting wipes. Antibacterial sprays. The cleaners we reach for without a second thought are part of our daily routines at home, at school, and at work. But new research is showing that these familiar products may come with hidden risks.

Libin Xu, associate professor of medicinal chemistry at the University of Washington School of Pharmacy, studies quaternary ammonium compounds—or “QACs”—a class of chemicals found in many disinfectants, particularly benzalkonium chlorides. His team has found that exposure to QACs is nearly universal.

“Almost every human sample measured so far has certain amounts of this compound, from very low to, occasionally, pretty high amounts,” Xu says. Traces have been detected in human blood, urine, feces, and breast milk, and even in the house dust—underscoring how easily these chemicals become part of our everyday lives.

Why does this matter? Recent studies by the Xu Lab found that QACs could affect cholesterol biosynthesis and lipid metabolism in neonatal mouse brains during the critical embryonic development period and disrupt gut microbiome homeostasis and metabolism in a mouse exposure model.1, 2 These compounds can be taken up via oral exposure or inhalation. The Xu Lab further found that QACs can be metabolized by human cytochrome P450 enzymes,3, 4 but they can accumulate in certain organs, such as the kidney and lung. Collaboration between the Xu Lab and Joanne Wang’s Lab found that while some QACs can be transported by transporters, they are not excreted efficiently,5 which may contribute to their accumulation in certain organs, such as the kidney. Furthermore, evidence suggests that QACs are preferentially excreted into the GI tract, hence the impact on the gut microbiome, which has been found to have numerous beneficial effects on human health. The figure below illustrates the fate of QACs in the human body based on the current knowledge.

 

While abundant studies in animals have demonstrated the potential detrimental effects of QACs, more research is needed to understand their effects on people. The Xu Lab’s ongoing projects funded by the National Institutes of Health (R01ES031927 and R01ES035021) aim to address the mechanistic gaps of QAC toxicity and their impact on human health.

“We’re not saying to stop cleaning,” Xu notes. “But it’s worth being aware of the potential health impact and choosing safer alternatives when you can.”

Simple changes—like checking labels, improving ventilation while cleaning, or using soap and water—can reduce your exposure without sacrificing safety. Because when it comes to protecting our health, knowledge is one of the most powerful tools we have.

UW’s new WE-REACH center to accelerate development of the ‘most exciting’ biomedical discoveries

With well over a billion dollars in research funding annually, the University of Washington is an engine of discovery and generates more than $15 billion in the state’s economy. Now, with a $4 million grant from the National Institutes of Health, UW has created a new integrated center to match biomedical discoveries with the resources needed to bring innovative products to the public and improve health.

“The University of Washington and regional partner institutions produce some of the most exciting biomedical discoveries and technologies in the world, but we always find it challenging to support their product development as they move into the early commercialization phases,” said the new center’s executive director Rodney Ho, a professor in the UW School of Pharmacy.

UW’s newly funded Washington Entrepreneurial Research Evaluation and Commercialization Hub (WE-REACH), with an annual budget boosted to $1.4 million by contributions from other partners, is organized to mentor and support biomedical entrepreneurs as well as provide project funding to fuel four to six biomedical startups a year with up to $200,000 each. Those projects will include innovative disease treatments, new drugs, diagnostics, genetic testing and health technologies. Ho said the center will support innovation steps not typically supported by research grants, such as human clinical trials or the development of and access to products.

In addition to the NIH, WE-REACH partners include the Institute of Translational Health Sciences, UW CoMotion, the Institute for Protein Design, the School of Pharmacy, and in collaboration with the UW’s Population Health Initiative Innovators will also receive guidance from multiple academic departments and regional institutions. Those institutions include the Fred Hutchinson Cancer Research Institute, Seattle Children’s and other universities in the five states that make up the WWAMI region.

“We are delighted to welcome WE-REACH as a partner,” said Tong Sun, executive director of the Institute of Translational Health Sciences. “At ITHS we are committed to accelerating the translation of discoveries to the clinic. WE-REACH investigators will be able to leverage ITHS programs and resources, so they can help us in our mission to improve health in our communities. This is a very exciting area of translation that we are happy to support.”

WE-REACH is one of five national commercialization hubs selected for funding by the NIH in 2019.

“The journey of biomedical discoveries to products that improve people’s health is expensive and risky. The process requires strategic investment of know-how as well as financial support from public-private partnerships,” said Ho.

“Spinning life science innovations out of research institutions requires expertise and funding that is hard to source in the academic environment,” adds Fiona Wills, assistant vice president, innovation development at CoMotion, UW’s collaborative innovation hub. “WE REACH builds on the infrastructure CoMotion has developed, including our gap fund and training, to provide  critical resources needed to de-risk promising technologies into pre-clinical and clinical development.”

The new center will be located in the South Campus Center on the University of Washington’s Seattle campus and at the Institute of Translational Health Sciences in UW Medicine South Lake Union. It will be staffed by Professor Rodney Ho, Executive Director; Terri Butler, Associate Director of Outreach and Partnerships; Matthew Hartman, Coordinator; Christine Jonsson, Administrator; and new hires in project management and technology management roles.

For information on the new center and how to submit a grant submission, please contact Matthew Hartman at WEREACH@uw.edu or 561-339-0676.

Announcement event: On Jan. 31, WE-REACH Executive Director Rodney Ho will formally launch the new center at the ITHS quarterly All-hands meeting at UW Medicine’s South Lake Union campus, 850 Republican Street Seattle, in the Orin Smith Auditorium. The meeting starts at 8 a.m.

UWSOP welcomes Gaurav Bhardwaj to Med Chem faculty

Gaurav Bhardwaj
Gaurav Bhardwaj, Assistant Professor, Medicinal Chemistry

Join us in welcoming Gaurav Bhardwaj, PhD, to the Faculty as Assistant Professor in the Department of Medicinal Chemistry. Gaurav earned his doctoral degree in Integrative Biosciences from the Pennsylvania State University. During his graduate work at Pennsylvania State University, he developed computational methods for studying evolution of highly divergent protein families.

From there, he undertook a post doctoral fellowship with Dr. Kit Lam at University of California, Davis, and then continued his post doc work at the Department of Biochemistry. He has been focused on the computational design of hyperstable constrained peptides and macrocycles with atomic-level accuracy, which opened avenues for custom design of peptide-based drugs that are cheaper, more effective and more stable than other alternatives.

“The UW Medicinal Chemistry department is very collaborative and features a broad diversity of expertise and resources, ranging from bioanalytical chemistry to drug metabolism,” said Gaurav. “Collaborations with other faculty members and students provide me a unique opportunity to accelerate the design and screening of new peptide-based therapeutics, as well as evaluate the pharmacokinetics and metabolism of these computationally-designed drug candidates.”

His lab is building a platform for the custom design of peptide-based therapeutics on computers. They are focusing on drug targets that are considered “undruggable” or ‘difficult-to-drug” using other therapeutic modalities—some of the most challenging problems in population health. His team is especially interested in designing novel antibiotics and non-opioid based solutions to treat chronic pain.

I love that my current research lets me combine tools and techniques from many diverse disciplines like computational sciences, chemistry, and biology. Building new molecules on a computer sounds like something straight out of a science fiction book. Being able to actually do that every day makes it a lot of fun.
Gaurav Bhardwaj, Assistant Professor, Medicinal Chemistry

Gaurav’s work could lead to significant breakthroughs in the development of targeted peptide therapeutics—of interest to many pharmaceutical and biotech companies, including Genentech, which provided support for his research at the UW. In addition, the UW Institute of Protein Design (IPD)—an internationally renowned institute that aims to design and characterize proteins for a wide range of applications in medicine and material technologies—and the UW School of Pharmacy Dean contributed to the ‘start up’ funds to ensure Gaurav’s important and collaborative work would be based here at the UW.

Outside his lab work, Gaurav said he loves reading books and exploring all the state and national parks in the Pacific Northwest. He is currently reading 21 challenges for the 21st century by Yuval Noah Harari. A little known fun fact is that he was once an extra in a really bad zombie movie! But being a zombie in the lab is unlikely. When we asked the new Seattlite how he likes his coffee, he said, “I like a 16 oz Mocha, twice a day! In fact, the only piece of wall art in my new office says, “With enough coffee, anything is possible.”

Welcome to the UW School of Pharmacy, Gaurav!

Faculty Legend Wendel Nelson Retires

After over 50 years of distinguished service at UWSOP and wide-ranging contributions to the profession of pharmacy, Professor Wendel Nelson retires this month.

Wendel Nelson
Wendel Nelson

Wendel joined the School as an Assistant Professor in 1965 in the Department of Pharmaceutical Chemistry, prior to its split into the current Departments of Medicinal Chemistry and Pharmaceutics in 1976. After promotion to Associate Professor, and then to Professor, Wendel served as Chair of the Department of Medicinal Chemistry from 1985-1999. As Chair, he provided vision for the design and construction of then ‘new’ H-wing space and our move from Bagley Hall in 1994. From 1978 until 2000, Wendel served as Director of the interdepartmental Training Program in Pharmacological Sciences, which has received over 40 consecutive years of continuing support from NIH. This grant provided support for many of our students, now alumni, of our PhD programs over the years.

Wendel’s contributions to PharmD training were also significant. Several generations of first and second year PharmD students learned the importance of medicinal chemistry in Pharmacy practice.  Wendel held PharmD students to a high standard that demanded a real knowledge of chemistry and pharmacology.

Wendel’s scholarly activities and research were highly impactful. His research provided fundamental insights into the regioselectivity of the metabolism of several important -blockers. Wendel’s lab also championed the use of synthetic active site-directed electrophilic probes to characterize opioid receptors, which provided deeper insight into their structure and function. More recently, Wendel participated in the determination of the stereochemical course of the metabolism of retinoic acid. In total, Wendel’s research included fundamental discoveries about the metabolism of therapeutic drugs, mechanisms of pharmacologic receptors, and the basic biochemistry of endogenous regulators of cell growth through the application of the principles of organic and synthetic chemistry.

Wendel’s scientific influence is evident in other ways, and he served on numerous review panels and editorial boards. Most notably, Wendel was the Senior Editor of the prestigious Journal of Medicinal Chemistry from 1989-2007, and he served as Chairman of the Division of Medicinal Chemistry of the American Chemical Society in 1966.  As a result, Wendel is nationally and internationally recognized for his research and editorial contributions in the field of Medicinal Chemistry.

The Department and the School are fortunate to have been the professional home of Professor Nelson. Please join us in congratulating Wendel on a remarkable career and in wishing him a very happy retirement.

Libin and Ed’s project will continue Libin’s research into the effects of benzalkonium chlorides (BACs) on human health. Benzalkonium chlorides are widely used as disinfectants in cleaning products, medical products, and food processing industries, but there is mounting evidence that points to them being toxic to developmental, reproductive, and neurological systems. Libin and Ed hypothesize that toxicities of BACs in liver and kidney are dependent on the activity of their metabolizing proteins.

In this innovative study, the team will use an integrated liver-kidney-on-chips microphysiological system developed by the laboratory of Ed Kelly, who co-led (with Dr. Jonathan Himmelfarb, Director, Kidney Research Institute) the kidney-on-a-chip project that launched to the International Space Station in 2019. By bringing together liver and kidney cells into connected three-dimensional microphysiological systems, they expect to gain deeper insight into the metabolism, disposition, and toxicity of BACs from the liver to the kidney.

Libin was part of the first UWSOP Faculty Innovation Fund Award team, with Brian Werth from the Department of Pharmacy. The UWSOP Faculty Innovation Award has led to several other ground-breaking projects that hold great promise for breakthroughs on some of the toughest challenges in population health:

  • Pharmacy’s Brian Werth and grant co-investigator UWSOP Medicinal Chemistry’s Libin Xu who continue their novel research into antibiotic resistance mechanisms in the superbug, methicillin-resistant Staphylococcus aureus (MRSA) with the support of a recent 4-year, $1.86 million NIH R01 grant.
  • An interdisciplinary team led by CHOICE Associate Professor Beth Devine, with Pharmaceutics’ Isabelle Ragueneau-Majlessi, ’10, and Pharmacy’s Jennifer Wilson-Norton, ’93, earned the award for their proposal, “Evaluating the Impact of Pharmacogenetic Testing on Clinical Outcomes in Retirement Communities: A Proof-of-Concept Feasibility Study.” UWSOP’s Jennifer Bacci, and Basia Belza, from the UW School of Nursing, will serve as advisors.
  • Professor Allan Rettie is leading a team that includes Co-Investigators Pharmaceutics Assistant Professor Bhagwat Prasad and Shreeram Akilesh of Pathology to find new personalized ways to slow the progression of the development of breast cancer by focusing in on an enzyme that can go rogue. The team hopes to identify inhibitors of a gene, CYP4Z1, which codes for a cytochrome P450 enzyme that is strongly associated with progression of the disease, a breakthrough that could lead to improved therapies that are personalized for a patient’s particular type of breast cancer.
  • Abhi Nath proposed to look at new ways to predict how the body metabolizes biologics, also known as “large-molecule” drugs or protein-based therapeutics. These drugs display immense potential in the treatment of many challenging forms of cancer, autoimmune disorders, and infectious and degenerative diseases. However, a major hurdle to their development is a lack of understanding of the factors that govern their pharmacokinetics and disposition.

Using Genetics to Decode Warfarin

Genome Sequencers

The potential impact of personalized medicine launched here at UW School of Pharmacy about twenty years ago, when Dave Veenstra’s graduate student Mitch Higashi,‘01, assembled a 200-member cohort of warfarin patients to study genetic factors influencing their drug response. They partnered with Allan Rettie in Medicinal Chemistry to go deeper.

Warfarin (CoumadinTM) has been a vital medication for many decades and used to prevent harmful clotting after a heart attack, stroke, or major surgery. There are risks with taking warfarin and patients taking the drug have to follow a strict regimen, including regular testing to ensure the dosing is correct.

“There is a narrow window between too much and too little effect,” explained Allan. “A small change in dose can have quite a large effect on blood processes.” If a patient’s dose is too high, it can cause excessive bleeding. Too low, and it can cause blood clotting. Getting that dose in the Goldilocks ‘just right’ zone has been a challenge for physicians and pharmacists for decades. Thus, there was great interest in being able to use emerging genetic testing technology to improve dosing for different populations for such an important drug.

The landmark paper by Mitch, Dave, Allan, and the UW research team, on the influence of CYP2C9 genetics on warfarin dosing was published in the Journal of American Medical Association (JAMA)in 2002. In 2005, the interdisciplinary team at UW School of Pharmacy led by Allan and Dave, which included Pharmaceutics’ Ken Thummel, ’87, identified an additional major genetic factor that led to significant shifts in how patients on the drug were dosed and monitored. The team identified a single gene, vitamin K epoxide reductase (VKORC1), which makes a protein that helps control clotting and is the key target of warfarin, as being responsible for 25% of the variance in warfarin dosages. Their discovery provided some explanation as to why certain people require a lower or higher dose of the drug.

The finding became a star in the case for personalized medicine— shifting medications and dosing based on a patient’s genetic profile. A few years later, the FDA revised warning label information on warfarin to raise physician awareness about the genetic impact.

Later studies continue to refine the team’s 2005 findings. In 2014, a team including Allan, Ken, Dave, and alumni Joshua Roth, ’12, and Denise Boudreau, ’02, completed the largest study of warfarin pharmacogenomics and major bleeding. They found a common CYP4F2 variant was associated with a 38% reduction in risk of major bleeding, potentially reflecting an interaction with warfarin and dietary vitamin K intake.

Research into the benefits of genetic testing continues with PharmD/PhD graduate student Lindsay Henderson’s research, with Allan, Ken, Dave, and others. Lindsay is first author on a paper looking at the unique pharmacogene variation that Alaska Native and American Indian (AN/AI) people have may affect warfarin disposition and therapeutic response. Her research shows promise for improving health outcomes for Alaska Native and American Indian people by using genetic testing.

Pharmacogenomics shows great potential to improve population health. Putting together the pieces of these genetic puzzles with consideration to the broad diversity of population health and managing the costs to substantiate the value of testing, continues to drive researchers at UW School of Pharmacy and beyond.

The story of the Department of Medicinal Chemistry is of a multi-generational approach to solving big problems in population health.

“Our network of faculty, alumni, and students is working to solve problems that affect millions of people worldwide: dementia, HIV, influenza, and other therapeutic areas. We train people to work at the molecular level to find better therapies and increased insight into these conditions.”—Bill Atkins, Sid and Joan Nelson Endowed Professor and Chair, UW Department of Medicinal Chemistry

Understanding and breaking down the mysteries embedded in small molecules and their mechanics is an effort that takes generations, not years, and one that accelerates as technology improves. No better place can that acceleration be seen than in the UW Department of Medicinal Chemistry.

Originally one department of pharmaceutical sciences, Dean Milo Gibaldi split it into pharmaceutics and medicinal chemistry to distinguish the disciplines. Looking back over the decades, we can see the Med Chem community like a family tree.

Med Chem Prof Al Huitric
Med Chem Prof Al Huitric

Faculty member Alain (Al) Huitric was a pioneer in applications of proton nuclear magnetic resonance (NMR) , recognizing its use for solving problems
of structural organic chemistry, and was a mentor to many. Dean Emeritus Sid Nelson said Al inspired him to pursue teaching and research. Bill Trager received his PhD in Med Chem under Al’s direction and Bill, Sid, and Allan Rettie all worked in his lab.

Forty years ago, Al secured funding for an NIH National Institute of General Medical Sciences (NIGMS) pharmacological sciences predoctoral training grant, which has been a significant source of support
for our graduate students. It is the longest continually running grant in UWSOP history. Training grants like this, research grants, and private support are critical with the waning of state support for research training. The UWSOP Corporate Advisory Board, one of the first corporate boards at the UW and vital partnership, was founded just over twenty years ago and brings our faculty and students together with leaders in the pharmaceutical industry, to enhance collaboration, training, networking, and research opportunities.

In the late 1970s, applications of mass spec technology to drug metabolism and pharmacokinetics became more prevalent, leading Bill Trager and Bill Howald to establish the UW Mass Spec Lab. When Tom Baillie joined Med Chem, he and Bill Howald acquired the latest equipment to support research across both departments, developing the interdisciplinary UW Mass Spectrometry Center.

The Future of Pharmacy


Celebrating 125 Years of Impact & Innovation

Our mission is to develop exceptional pharmacy leaders and researchers, discover solutions to improve population health, and serve the health and well-being of the public, locally and globally…even in space.

“We aren’t waiting for the future to happen. We are proactively accounting for what these changes mean and preparing our student pharmacists and researchers to think critically and be able to adapt to whatever policies, innovations, or technologies are to come.”.—Sean D. Sullivan, Professor and Dean, UW School of Pharmacy

At the University of Washington School of Pharmacy, we embrace diverse perspectives, beliefs and cultures and work to serve the greater good of society.

When pharmacists are open and educated on how to support their patients, the quality of care improves. Through our training, research, and outreach, we make sure we are taking care of people–whatever their needs are. Our work matters and we make a difference.

In 2009, then student, now alumna, Joanna Preker, ’12, worked with I2P2 Endowed Clinical Professor Don Downing, ’75, to advocate for improved patient access to sexual and reproductive health services. Founded and named by Joanna, Pharmacy for Reproductive Education and Sexual Health (PhRESH) was a first-of-its-kind pharmacy student organization. Her novel efforts were successful, resulting in increased access to health care for women and families in Washington and elsewhere.

Sam Miller, PharmD candidate, class of 2020, an active PhRESH member, is leading the way in supporting transgender patients. He has created a toolkit and resources to train pharmacists in how to communicate they are a welcoming pharmacy—from asking for preferred pronouns to wearing pronoun buttons on lab coats. Sam’s programs include the technical aspects of supporting transgender patients including training them on injecting hormones, helping with insurance coverage questions, and more. Sam won an award at the WSPA Northwest Pharmacy Conference for his research poster on training pharmacists to support transgender patients and recently did a rotation at the Human Rights Campaign.

The team reconvened Saturday, May the 4th, 2019...ever hopeful that this time the launch would be successful.
The team reconvened Saturday, May the 4th, 2019…ever hopeful that this time the launch would be successful.

We are boundless in our efforts to improve health care. In 2019, faculty members Ed Kelly, Cathy Yeung, ’05, ’13, and their team, along with collaborators at UW Medicine and Kidney Research Institute, watched live at Kennedy Space Center in Cape Canaveral as the Kidney on a Chip project launched to outer space. The project aims to help people on Earth and future astronauts on missions to Mars. One of the challenges of spending years in microgravity is that there is a high increase in kidney-related health problems, including osteoporosis and kidney stones. The team hopes to gain insight into that rapid aging process through the microphysiological chips.

Thanks to donors like Richard, ’54, and Susan Coar, we continue to support forward-looking research projects like those supported by UWSOP Faculty Innovation Awards. Pharmacy’s Brian Werth and Medicinal Chemistry’s Libin Xu received funds to support their novel research into antibiotic resistance mechanisms in the superbug, methicillin-resistant Staphylococcus aureus (MRSA), which has led to a $1.86M NIH grant.

An interdisciplinary team led by CHOICE Professor Beth Devine, with Pharmaceutics’ Isabelle Ragueneau-Majlessi, ’10, and Pharmacy’s Shelly Gray and Jennifer Wilson Norton, ’93, earned the Faculty Innovation Award funds for their research on using pharmacogenetic testing on clinical outcomes in retirement communities. UWSOP’s Jennifer Bacci, and Basia Belza, from the UW School of Nursing, are serving as advisors. Abhi Nath is looking for new ways to predict how the body metabolizes biologics, also known as “large-molecule” drugs or protein-based therapeutics. These drugs display immense potential in the treatment of many challenging forms of cancer, autoimmune disorders, and infectious and degenerative diseases, but little is known about the factors that govern their pharmacokinetics and disposition. Professor Allan Rettie’s team seeking new personalized ways to slow the progression of the development of breast cancer by focusing in on an enzyme, CYP4Z1, that can go rogue, which may lead improved therapies that are custom for a patient’s particular type of breast cancer.

These interdisciplinary approaches to training are indicative
of the multi-disciplinary approach to solving problems of population health. We are proud of the tradition of alumni who are both pharmacists and researchers, including Dave Veenstra, Beth Devine, Jean Dinh, ’05, ’09, ’14, Ryan Hansen,’03, ’12, Jonathan Watanabe, ’98, ’08, ’12, Cara McDermott, ’11, ’12, ’16, Cathy Yeung, Cate Lockhart, ’04, ’13, ’16, ’16, Todd Lee,’01, Kai Yeung, ’15, and Lindsay Henderson. The problems of health and the health care system are intertwined and complex. It will take leaders like our alumni to create a world where all people can live healthier and more fulfilling lives.

In 2018, Abhi Nath, ’08, was named recipient one of that year’s UWSOP Faculty Innovation Awards. The awards provide financial support of up to $20,000 each for high-risk, innovative research projects.

Abhi proposed to look at new ways to predict how the body metabolizes biologics, also known as “large-molecule” drugs or protein-based therapeutics. These drugs display immense potential in the treatment of many challenging forms of cancer, autoimmune disorders, and infectious and degenerative diseases. However, a major hurdle to their development is a lack of understanding of the factors that govern their pharmacokinetics and disposition.

“We don’t yet recognize the ‘flags’ that indicate that a given large molecule may behave problematically or unpredictably, as we do for conventional small molecule drugs.” —Abhi Nath, Assistant Professor of Medicinal Chemistry

This knowledge gap makes the development of biologics challenging, increasing the time and costs to bring these promising medications to market. By using a combination of biophysical measurements and machine learning analyses, the team anticipated they would shed new light on the disposition of protein-based therapeutics, and give trainees hands-on experience in modern data science techniques.

Dennis Goulet

Thus far, the UWSOP Faculty Innovation Award has led to one publication by Medicinal Chemistry PhD graduate student Dennis Goulet, former Magnuson Scholar and first recipient of the Scott Grimm Fellowship. Dennis is first author on, “Toward a Combinatorial Approach for the Prediction of IgG Half-Life and Clearance” in ASPET’s Drug Metabolism and Disposition. The paper’s co-authors include Michael J. Watson, William M. Atkins, and Abhinav Nath, all from the UWSOP Department of Medicinal Chemistry, as well as colleagues from Janssen Research & Development.

In addition, Medicinal Chemistry PhD graduate student Hayli Larsen will present work enabled by the award at the Protein Society Annual Meeting in Seattle this summer.

Past recipients of the Faculty Innovation Award include:

  • Pharmacy’s Brian Werth and grant coinvestigator UWSOP Medicinal Chemistry’s Libin Xu who continue their novel research into antibiotic resistance mechanisms in the superbug, methicillin-resistant Staphylococcus aureus (MRSA) with the support of a recent 4-year, $1.86 million NIH R01 grant.
  • An interdisciplinary team led by CHOICE Associate Professor Beth Devine, with Pharmaceutics’ Isabelle Ragueneau-Majlessi, ’10, and Pharmacy’s Jennifer Wilson-Norton, ’93, earned the award for their proposal, “Evaluating the Impact of Pharmacogenetic Testing on Clinical Outcomes in Retirement Communities: A Proof-of-Concept Feasibility Study.” UWSOP’s Jennifer Bacci, and Basia Belza, from the UW School of Nursing, will serve as advisors.
  • Professor Allan Rettie is leading a team that includes Co-Investigators Pharmaceutics Assistant Professor Bhagwat Prasad and Shreeram Akilesh of Pathology to find new personalized ways to slow the progression of the development of breast cancer by focusing in on an enzyme that can go rogue.

Brain cholesterol, SLOS, & autism

The UW Medicinal Chemist studied neural chemistry and biology to understand the underlying mechanism that cause birth defects, behavioral problems, and autism

You probably know about good and bad cholesterol as it relates to your heart—but did you know that your brain needs cholesterol too? The brain’s cholesterol is essential to fetal development—a lack of which can lead to birth defects and conditions like Smith-Lemli-Opitz syndrome (SLOS), a disorder caused by mutations in the last step of cholesterol biosynthesis, DHCR7.

SLOS has a high correlation with autism: over 70% of children diagnosed with SLOS also display an autism spectrum disorder. It also tends to be underdiagnosed due to fetal lethality or takes years to be diagnosed as some mild cases show up as behavioral problems, not physical defects.

But getting more cholesterol to the brain isn’t as simple as taking a supplement. The brain makes its own cholesterol and cholesterol in the peripheral tissues or blood does not cross the blood-brain barrier. Any therapies for SLOS must be able to pass through the blood-brain barrier to be effective.

Assistant Professor Libin Xu and his team want to understand the molecular mechanisms underlying SLOS so they can test treatments that can get to the brain. Understanding the mechanisms behind SLOS could also lead to treatments for autism due to the strong correlation between SLOS and autism.

“The marriage of chemistry and biology gives me a unique way to look at molecules and the impact small molecules have in disease pathology.”—Libin Xu, Assistant Professor of Medicinal Chemistry

There are two causes the team are looking at: genetic mutations in DHCR7 that result in a build up of a reactive cholesterol precursor, 7DHC, that negatively affects brain development, as well as inhibition of the same enzyme by environmental molecules or drugs, such as benzalkonium chloride, a common ingredient in hand wipes and disinfectants like Clorox and Lysol, and some antipsychotic and antidepressant drugs—such as Abilify and Haldol. 

Simply put, the team is exploring how these common environmental compounds and prescription medications cause the same biochemical  defects observed in SLOS, aiming to minimize damages of such exposure on embryonic and brain development and develop treatments.

The team is using a combination of mass spectrometry and mouse models to study the disease and what happens when the reactive cholesterol precursor, 7DHC, builds up. They want to find a way to inhibit the formation of toxic metabolites of 7DHC or inhibit their downstream detrimental effects using small molecules. Libin sees some promise in identifying combination therapies that mitigate the risk of SLOS-like symptoms in the case of mothers taking antidepressants or antipsychotics.

Women who are expecting may want to speak with their doctor if they are taking such drugs or using products containing benzalkonium chloride during pregnancy and lactation. However, there are adverse side effects of untreated depression, including low birthweight and preterm labor, which may outweigh the risk to the fetus’ development, so stopping medication without a provider’s guidance is not recommended.

This five-year National Institutes of Health R01 grant (R01HD092659) was funded in 2017 for $1.3M.

Kidney on a Chip has gone to outer space..and returned to Earth!

Ed Kelly spoke at NASA a few days before the launch happened, explaining why the team is sending Kidney on a Chip to the International Space Station.
Ed Kelly spoke at NASA a few days before the launch happened, explaining why the team is sending Kidney on a Chip to the International Space Station.

What did it take to send delicate kidney cells into space to be studied by astronauts wearing big, clunky gloves who may, or may not, have a background in biochemistry? We popped into the lab to talk to Ed Kelly and Cathy Yeung to find out.

Dawg Scripts: Why did you put kidney cells on a chip?

Associate Professor Ed Kelly: As a Toxicologist, we talk about the “Three Rs” when it comes to our research: reduce, refine, and replace. That means we are looking for ways to reduce animal testing, refine processes, and—where we can—replace animal testing. With Kidney on a Chip, we have a better model than testing kidney cells on plates under the microscope, in petri dishes, or with animals. The tubules—about the size of a human hair—housing the cells in the chip mirror the tubules in the kidney in the body and, like the kidney in the body, we can move fluid through the tubules and have more information than we would otherwise. For example, we did some testing using a powerful antibiotic. We knew the antibiotic was toxic but we didn’t know why. By using Kidney on a Chip, we were able to identify the biomarkers of toxicity, showing that the antibiotic was indeed toxic to renal tubular cells.

“We are planning for failure, even though that’s not an option.”—Ed Kelly, Associate Professor of Pharmaceutics

DS: So then why send chips to space?

Research Assistant Professor Cathy Yeung, ’05: Kidney disease can take years to develop. Microgravity accelerates kidney disease or dysfunction, and other conditions in astronauts, so the goal is to see the impact low gravity will have on the cells in the microphysiological chips. We anticipate learning more about how kidney stones, osteoporosis, and proteinuria (an abnormally high amount of protein in urine which indicates kidney damage) begins and develops. There aren’t many effective treatments for kidney stones currently. Last year, the main “recommendation” for treatment was to ride a roller coaster in hopes of dislodging the stone (we don’t recommend this course of treatment). Instead, we hope to gain some insights into how they develop that may lead to improved therapies. 

DS: What can you tell us about the cell samples you are using? 

CY: The kidney cells used come from two men and two women so we will be able to see gender differences, which is important for diseases like osteoporosis which has a higher incidence among women. All of this research is important for people on Earth, as well as the future of missions to Mars when people will be in microgravity for years. We have questions about how kidneys process Vitamin D and hope to gain insight about osteoporosis and how to prevent it from this research.  

Cathy Yeung and Ed Kelly were asked when the launch would happen after the third launch delay. They responded in a precise scientific way.
Cathy Yeung and Ed Kelly were asked when the launch would happen after the third launch delay. They responded in a precise and scientific way.

DS: What are some of the challenges of sending the chips to space?

EK: We’ve had a lot of logistical challenges. First of all, we have to make the level of science very easy for
astronauts who will be working with large gloves. Some of the astronauts have advanced degrees in science, but we had to make sure that whoever is running the experiment that day could do the work needed. Another challenge was taking the 50 cubic feet of space we use to run the experiments in our lab down to a box about the size of a microwave to fit in the rocket and space station, which is why we partnered with BioServe Space Technologies at University of Colorado Boulder.

DS: Will there be a lab in space? 

Very early Friday morning May 3, 2019, the team gathered to watch the launch...which was scrubbed 15 minutes before go time. It was rescheduled for very early in the morning Saturday, May the 4th.
Very early Friday morning May 3, 2019, the team gathered to watch the launch…which was scrubbed 15 minutes before go time. It was rescheduled for very early in the morning Saturday, May the 4th.

CY: There will be experiments running at precisely the same time on the ground as in the Space Station while the Chips are in space. Our team of faculty and graduate students will be on site at Kennedy Space Center in Florida running the experiments on Earth. So we have to create labs that will go to space and also recreate our lab in Florida. The box going to space with the chips has to be specially designed to handle the stressors of coming in and out of atmosphere, the vibrations in breaking the sound barrier, and dropping to Earth on its return. The kidney cells have to be kept at a constant 37 degree C temperature, which requires three different power sources from the time the chips are built on the lab on Earth, transferred to the rocket, and launched into space. We don’t know what will happen and we are doing our best, working with our BioServe partners, to anticipate as many obstacles as possible. 

DS: What’s special about this project?

EK: We are proud that the University of Washington is the only university with two projects launching to the International Space Station as part of this nationwide Organ on a Chip project funded by the NIH and CASIS. Our project will be the first to launch and the Heart on a Chip by Deok-Ho Kim in Bioengineering will be the second. 

Below are scenes from the Launch that happened on May 4, 2019. May the Fourth Be With You, was the rally cry of the day after multiple delays.

Lindsay Henderson with her award-winning poster, “Functional Characterization of Novel CYP2C9 Variants Found in an Alaska Native Population”

Congratulations to PharmD and Pharmaceutics PhD student Lindsay Henderson who received the 2nd place graduate student poster presentation award for the Drug Metabolism and Disposition Division of ASPET (American Society for Pharmacology and Experimental Therapeutics).

Lindsay Henderson, here pictured with Med Chem Professor Allan Rettie
Lindsay Henderson, here pictured with Med Chem Professor Allan Rettie

Her poster titled, “Functional Characterization of Novel CYP2C9 Variants Found in an Alaska Native Population,” focuses on genetic polymorphisms in CYP2C9, an important cytochrome P450 responsible for the metabolism of medications across many therapeutic classes including non steroidal anti-inflammatories, angiotensin II blockers, as well as narrow therapeutic index drugs such as (S)-warfarin and phenytoin. 

Comprehensive in vitro experiments were performed to elucidate the function of novel CYP2C9 protein variants found in an Alaska Native population.

The team’s findings suggest that carriers of the CYP2C9 N218I and M1L variant alleles would be at risk of exacerbated therapeutic effects from narrow therapeutic index drugs that rely on CYP2C9 for their metabolic clearance.

Her co-authors include UWSOP researchers, Matthew G McDonald, Catherine K Yeung, ’05, Allan E Rettie, and Kenneth E Thummel, who served as Senior Author.

Congratulations, Lindsay!

The launch date may be subject to change, again. We will continue to update this page as we get more news!

A kidneys-on-a-chip experiment is being readied at Cape Canaveral, Florida, to fly aboard a SpaceX Dragon C19/Falcon 9 supply shuttle to the International Space Station.  At an altitude of 250 miles, the chip technology will be used to study reduced gravity and other space flight conditions on kidney physiology.

The unmanned SpaceX mission CRS17, contracted with NASA, was slated for late April and is delayed until May 1. The launch date will not be official until after the Flight Readiness Review

Three other organs-on-chips will be on-board for studies of lung host defenses, the blood-brain barrier, and musculoskeletal diseases. Developed by research groups nationwide, the four projects are part of the Tissue Chips in Space program. This will be the second time that National Institute of Health tissue chips have been flown into space.  The first study was on aging and the immune system.

The National Center for Advancing Translational Sciences at the National Institutes of Health spawned the creation of these small, bioengineered tissue chips, which model the physiology of human organs on a living, 3-D microscale.  They have been developed to speed the search for new drugs and therapies and get these treatments to patients faster. Researchers use the tissue chip systems to study healthy and diseased states, and to test medications and other treatments.

Scientists at UW Medicine and the University of Washington School of Pharmacy, with collaborators in industry and other agencies, designed the kidney-on-a-chip component.

Several of them are at Cape Canaveral now preparing the devices.

The credit-card size chips contain fluid microchambers lined with human-derived kidney cells. For this space mission, these chips will simulate one type of kidney tubule.

In actual kidneys, similar anatomical structures regulate absorption and release of substances in the blood, among them medications and toxins.  Vitamin D metabolism, important for bone strength, takes place in kidneys.  Kidneys also protect against fluid retention and other biochemical imbalances.

Aboard the International Space Station, where they will be exposed to microgravity for about two weeks, the organs-on-a-chip might reveal why kidney problems occur often and quickly among astronauts.

The chief scientists are Ed Kelly, associate professor of pharmaceutics, UW School of Pharmacy; Jonathan Himmelfarb, kidney disease specialist at UW Medicine and professor of medicine, Division of Nephrology, UW School of Medicine; and Cathy Yeung, research assistant professor of pharmacy.

They noted that this space study could provide insights into the development and overall health implications of kidney diseases on Earth, in less time than is possible with terrestrial research in humans.

Kidney disease occurs in about 10 percent of adults. Treatment can diminish quality of life. New tools, like the kidney chips, could help find ways to prevent or treat kidney problems in astronauts, as well as in people who will never venture into space.

“Certain conditions related to poor kidney health appear more rapidly in space and could have life-long consequences,” Himmelfarb said. These include protein in the urine, bone loss, and kidney stones.

“Aging of cells accelerates in space,” he added, indicating that organ-on-a-chip space research could uncover medical knowledge useful beyond a specific disease.

“We’ll be able to see in a matter of days what might take months on Earth,” the researchers said.

While microgravity alone might harm kidneys, the scientists also pointed out that astronauts are confined to a closed environment, are exposed to questionable chemicals, eat an unusual diet, and conserve and recycle water for drinking. Any of these could be rough on already vulnerable kidneys.

According to Kelly, the kidney-on-a-chip technology will evaluate how diminished gravity affects the ability of tubules, in both males and females, to conduct the basic work of kidneys.  He explained that kidney cells sense gravitational forces in ways that direct the cells to carry out their activities.

“Kidney tubules are polarized,” explained Yeung, “and have an inside and outside. We are curious to see if the cells still stay polarized without Earth’s gravity, and what effect this might have on kidney cell function and on disease progression.“

The cells’ shape, spatial orientation and response to fluid flow could be disrupted in space. This distortion could alter how the cells that line the tubules transport water, electrolytes, vitamins and toxins, and could make tubules prone to damage from proteins or other biochemicals.

The researchers plan to send 24 Nortis Triplex Chips to the International Space Station in temperature and carbon dioxide pump assemblies.

While intergalactic space missions are still a stargazer's dream, kidney studies in Earth's orbit will likely make better treatment a reality on our planet.

After berthing, these will be placed in incubators and later put in a Life Sciences Glovebox. At the end of the experiment, they will be preserved and cooled to await transport back to Earth.

“We had to shrink the size of our usual equipment to fit the tight quarters of the space station,” Himmelfarb said.  It was like shoehorning a refrigerator into a microwave oven, while maintaining proper environmental conditions for the experiment.

“We had to make some 270 modifications to fit the setting of the International Space Station,” the researchers explained.  Precautions were taken to keep the chips from shattering and creating a free-floating fragment hazard.

“On Earth, studies can be repeated. On the ISS, we have only one shot to get this experiment right. It will be a tense time for us,” Himmelfarb said.

The set up took into account the realities of working in orbit. The astronauts will perform experiments while wearing cumbersome gloves and space suits. Miniaturization and automation, however, should simplify their tasks – and provide new ideas for making such experiments easier to perform on Earth.

“One of the cool things about being at Cape Canaveral is that we can watch the astronauts do the experiments in real time,” Himmelfarb said.

Meanwhile, in normal gravity on Earth, a UW team will conduct the same protocols on kidney chip cells from the same donors, to obtain comparative, control data.

This summer, a second tissue chip launch to the ISS will test potential drug therapies for the biological changes observed during this mission.

Future research, led by UW bioengineering associate professor Deok-Ho Kim, will send hearts-on-chips to the International Space Station.  Those studies will look at the influence of extended periods in space on heart muscle contractions. Besides causing kidney changes, space flight reduces cardiovascular fitness.

The National Center for Advancing Translational Sciences at the National Institutes of Health and the International Space Station United States National Laboratory, are funding Tissue Chips in Space, in collaboration with the National Aeronautics and Space Administration.

Kim and Kelly are scientists at the UW Medicine Institute for Stem Cell and Regenerative Medicine Research. Kelly and Himmelfarb are investigators at the Kidney Research Institute, a collaboration of Northwest Kidney Centers and UW Medicine.

Kelly also admits he is a sci-fi space exploration nerd who has a Star Trek Next Generation Borg Cube in his office.

Nath lab makes progress against neurodegenerative conditions

Hope Barnes Fellow and graduate student Hannah Baughman continues to discover more about molecular chaperones and their potential in treating Alzheimers
Hope Barnes Fellow and graduate student Hannah Baughman continues to discover more about molecular chaperones and their potential in treating Alzheimer’s disease

We revisited Abhi Nath and his lab team to see how their work to improve the diagnosis and treatments of neurodegenerative conditions, including Alzheimer’s, Parkinson’s, and Chronic Traumatic Encephalopathy (CTE) was progressing.

The team hopes to discover improved diagnostic tools and therapies by learning how brain proteins such as Tau, β-Amyloid and α-Synuclein start misbehaving in these diseases.

The challenge is that proteins like Tau are very flexible moving targets, almost like Jell-O™, making it hard to use traditional tools of structural biology. One of their long-term goals is to develop new small molecules that can either slow down protein aggregation, or bind to particular types of aggregates to act as a tracer.

Such tracers or tags can currently be used to detect protein aggregates in brain scans, but struggle to distinguish which particular proteins are involved, or whether aggregates are harmful or benign.

“Newer, more specific tracers could enable earlier, more accurate diagnosis of conditions like Alzheimer’s and Parkinson’s and ultimately improve outcomes for patients and their families.”–Abhi Nath

“Alzheimer’s is such a challenging and scary disease. Any di erence we can make there would mean so much—a lot of us have been a ected and it’s only going to get worse as the population gets older,” remarks Abhi Nath (pictured right with David Baggett, le
“Alzheimer’s is such a challenging and scary disease. Any difference we can make there would mean so much—a lot of us have been affected and it’s only going to get worse as the population gets older,” remarks Abhi Nath (pictured right with David Baggett, left) Photo: Alex Levine

Graduate student David Baggett’s computer models can screen millions of compounds to identify molecules capable of binding proteins like Tau, and either detecting or stopping the aggregation process. As they learn more about how these compounds recognize Tau, they can perhaps engineer more effective, safer variants that could serve as the basis for new treatment and diagnosis strategies.

A new industry partnership with Takeda Pharmaceutical Co. will accelerate their research. “The Takeda award provides us with support and resources to work on designing, synthesizing, and testing new molecules— derivatives of ones that David found,” shared Abhi. “We will also use his methods to identify other novel molecules with similar activity.”

Hope Barnes Fellow and graduate student Hannah Baughman continues to discover more about molecular chaperones, which are natural defenders against protein aggregation. The NIH recently elected to support this work under a special program for Alzheimer’s disease and related dementias.

“If we can turn up the right sort of activity for the right type of chaperone, that may advance our ability to treat Alzheimer’s, Parkinson’s, and CTE,” said Abhi. “My vision is to use the advances that have been made in protein biophysics over the past 10–15 years to find new ways to diagnose these conditions early and improve treatments and outcomes for patients. Given how much we have learned about Tau and similar proteins, and our partnerships in academia and industry, I am very excited about our prospects.”

Pharmacy’s Brian Werth and grant coinvestigator UWSOP Medicinal Chemistry’s Libin Xu will continue their novel research into antibiotic resistance mechanisms in the superbug, methicillin-resistant Staphylococcus aureus (MRSA). The team were recently awarded a 4-year, $1.86 million NIH R01 grant as principal investigator, which is an exceptional accomplishment for a young investigator.

With Libin’s expertise in ion mobility-mass spectrometry (IM-MS) analysis of lipids and Brian’s expertise in antibiotic resistance, they are working to understand the mechanisms of cross-resistance among antibiotics that target the bacterial cell membrane and cell wall.

This work could lead to the identification of novel targets for resistance-modifying therapeutics or more sensitive diagnostics to detect resistance.

In addition, the team received a UW Royalty Research Fund award of $38,175 for their project, “Targeting Altered Lipid Metabolism in Antiobiotic-Resistant Staphylococcus Aureus.” The RRF is funded from royalty and licensing fee income generated by the UW technology transfer program. The fund supports UW faculty seeking to advance new directions in research in disciplines for which external funding opportunities are minimal; for faculty who are junior in rank; and if the award might provide opportunities to increase applicants’ competitiveness for subsequent funding.

It’s bittersweet to announce that our long-time colleague, Dr. Kent Kunze, has stepped down as Departmental Chair and retired from the faculty.  Kent has been a valued member of the faculty since 1990, and for the past 4 years he has served as ‘the Chair.’  During his time on the faculty, Kent played a critical role in the research activities that further strengthened our ‘brand’ in drug interactions and mechanistic drug metabolism.

The Iceman Ski-eth

Kent has continued to be a resource for all seeking expertise in Cytochrome P450 enzymology and inhibition.  Most recently, Kent provided leadership and vision that helped to launch new research initiatives of our younger faculty.  Kent says that the near future includes some golf, sailing, and hiking. We wish him a happy retirement and say a heartfelt ‘thanks’ for being an important part of our village.

Nath lab team takes aim at Alzheimer’s

Alzheimer’s disease affects about 5 million Americans, a number projected to roughly triple by 2050. The urgency of this grave population health challenge is with Abhi Nath and his team of researchers every day as they seek new options to treat and manage Alzheimer’s and related diseases. The key appears to lie with a process called protein aggregation, which links Alzheimer’s, Parkinson’s, and Chronic Traumatic Encephalopathy (CTE)—a disease that affects people, such as military veterans and football players, who have suffered concussions or traumatic brain injury.

“At the molecular level, particular proteins in the brain are misbehaving,” said Abhi. A major culprit in Alzheimer’s disease and CTE is a disordered protein called tau. “Proteins are supposed to fold like origami to function. When you have a misfolded protein, they tend to stick together—in the wrong way. That phenomenon of aggregation is the underlying cause of diseases like Alzheimer’s.”

Understanding how the disease begins and what happens at a molecular level would lead to improved diagnostic tools and therapies, but it’s a major challenge because proteins like tau are very exibly moving targets, making it hard to use traditional tools of structural biology. “Nothing in our current tool belt works well with these targets,” said Abhi. Instead, the team are developing new approaches, drawing on a variety of scientific disciplines in order to have the biggest long-term impact.

“We can manage symptoms, but we have a long way to go for a therapy for Alzheimer’s. It’s like playing Tetris with Jello—there are hundreds of thousands of chemicals that could t tens of thousands of gaps and we are looking for the right match.”—Abhi Nath, Assistant Professor of Medicinal Chemistry and Plein Center for Geriatric Pharmacy Researcher

Eri Nakatani-Webster, ’13, a KL2 scholar and post doc, is working to develop sophisticated mathematical models of protein aggregation that will make it easier to under- stand and predict how a drug or other binding partner will affect the process.

Graduate student Hannah Baughman is deeply focused on understanding how disordered proteins interact with the body’s own defense mechanisms against protein aggregation: molecular chaperones. These molecular machines can recognize when a protein is misfolding and help it refold into its correct structure, which may lead to new ways of helping our bodies protect us from these diseases.

Graduate student David Baggett’s computer models of tau can screen millions of compounds to identify new molecules capable of binding different stages in the aggregation pathway. In addition to accelerating the pace of drug discovery, David’s work could improve early diagnosis—a particularly important challenge in diseases like Alzheimer’s and CTE, where cognitive symptoms manifest well after the damage has been done at the cellular level and it may be too late to treat the illness.

Graduate student Eleanor Vane is taking a counter-intuitive approach by investigating whether aggregation-prone proteins could actually play a beneficial role by controlling bacterial infections and fungal growth.

“Here in Medicinal Chemistry, we take what we learn every day about the biophysics of misfolding proteins and connect that to improving human health,” shared Abhi. “It is incredibly hopeful and fulfilling work, with great promise.”

Libin Xu and Brian Werth Receive Royalty Research Fund Award

Dr. Libin Xu
Dr. Brian Werth

Libin Xu, Assistant Professor of Medicinal Chemistry, and Brian Werth, Assistant Professor of Pharmacy, have received a Royalty Research Fund award of $38,175 for their project, “Targeting Altered Lipid Metabolism in Antibiotic-Resistant Staphylococcus Aureus.”

The RRF is funded from royalty and licensing fee income generated by the UW technology transfer program.  It supports UW faculty seeking to advance new directions in research in disciplines for which external funding opportunities are minimal; for faculty who are junior in rank; and/or if the award might provide opportunities to increase applicants’ competitiveness for subsequent funding.

“Methicillin-resistant staphylococcus aureus (MRSA) strains are becoming more resistant to the cell-membrane targeting antimicrobials that help manage these infections,” said Dr. Xu.  “This may be due to genetic mutations that lead to changes in the cell membranes of these MRSA strains.”

Dr. Xu and Dr. Werth, as co-Principal Investigators on the project, will test their hypothesis that changes in cell membranes contribute to the antimicrobial resistance, and that these changes can be modulated using small molecules of known lipid biosynthesis inhibitors to re-sensitize the mutated MRSA strains.

Congratulations to Drs. Xu and Werth on being funded for this exciting project!

Xu Lab Awarded NSF Grant to Study Lipid Peroxidation

Dr. Libin Xu, Assistant Professor of Medicinal Chemistry

Lipid peroxidation is the process in which a reactive atom or group of atoms (free radicals) capture electrons from the lipids in cell membranes, resulting in cell damage. This process plays an important role in the pathophysiology of many human conditions – aging, atherosclerosis, cancer, and neurodegenerative diseases – so it is critically important to understand the mechanisms by which these molecules are oxidized.

The Libin Xu lab in Medicinal Chemistry has been awarded a three-year grant from the National Science Foundation in the amount of $405,000, which the lab will use to research the fundamental chemistry of free radical oxidation of organic molecules, including biologically important lipids and vitamins.

“The goal of this grant is to develop a chemical method, called ‘peroxyl radical clock,’ to measure the rate-determining steps of lipid peroxidation,” said Dr. Xu. “We want to understand the reaction mechanisms of biologically important lipids, including the biosynthetic precursors of cholesterol, arachidonic acid (in collaboration with my colleague Dr. Rheem Totah), and fat-soluble vitamins A, D, and K.”

This project could have broad benefits to human health: understanding the reactivity of these lipids would allow the team to assess the susceptibility of human tissues to oxidative stress, particularly when the levels of oxidizable lipids are elevated. The oxidation products can also be biomarkers of human disease. Many of these products have some detrimental effect on physiological processes, and being able to measure and assess them would give health scientists more information on which to base effective therapies.

“Most of the preliminary data for this project was generated by outstanding undergraduate researchers in my lab,” said Dr. Xu. “Andrew Dinh, David Lee, and David Kennedy have all moved on to the next chapter of their careers, but they made a strong impact on our research. I was very fortunate to work with them during the startup years of my lab.” He added, “This is a good example of how undergraduate researchers can truly contribute to basic science.”

Remembering Bill Howald, UWSOP Mass Spec Director

Bill Howald (pictured center) in the Mass Spec lab with then graduate student Shimako Oishi and former Dean Sid Nelson.
Bill Howald (pictured center) in the Mass Spec lab with then graduate student Shimako Oishi and former Dean Sid Nelson.

William “Bill” Howald passed away August 14, 2017 in Salem, Oregon at the age of 76 after a brief illness. After retirement, Bill and his wife Carole moved to Oregon to be closer to family.

Bill joined the School of Pharmacy, Department of Medicinal Chemistry as a Research Technologist working in the Mass Spectrometry Facility. He became the Manager of the Facility and Lecturer in Medicinal Chemistry in 1983 and retired in 2008 after building a world class center.

During his tenure the Mass Spectrometry Center provided cutting edge mass spectrometers and other tools to support the diverse and evolving research programs in proteomics, drug metabolism and biochemical toxicology in the School of Pharmacy as well as the in the larger UW research community. He played an essential role in the research productivity of the school working closely with Bill Trager, Tom Baillie, Sid Nelson, Allan Rettie, Rene Levy, Ken Thummel and countless others.

Perhaps equally significant to the mountains of his research accomplishments was the extensive hands-on training that Bill provided to the many generations of graduate students and post-doctoral fellows that have moved through our training programs. These scientists, now spread through the world, provide a long and lasting testimony to Bill’s legacy.

Mass spectrometers are expensive, powerful, and unfortunately highly temperamental instruments. Medicinal Chemistry department chair Kent Kunze said, “Training new students required the endless patience and a good sense of humor for which Bill was famous. Bill was a consummate scientist and wonderful colleague and friend to all.”

The family has asked that gifts in remembrance of Bill’s life and work be made to the William Howald Mass Spectrometry Support Fund at the UW School of Pharmacy at http://bit.ly/BHowald.

Med Chem’s Mike Guttman Receives Royalty Research Fund Award

Asst Prof Mike GuttmanThe Royalty Research fund (RRF) is sponsored by UW’s Office of Research to help faculty establish new research programs.  The program is funded from royalty and licensing fee income generated by the UW Technology transfer program.  These one-year awards have been offered semi-annually since 1992.

Med Chem Assistant Professor Mike Guttman was recently chosen to receive an RRF award of $36,665 for his project, “Gas Phase Hydrogen/Deuterium Exchange to Distinguish Isomeric Carbohydrates.”  Dr. Guttman’s aim is to develop new mass spectrometry techniques for analyzing various sugar structures.

A variety of complex sugar structures cover most of the extra-cellular environment of higher-level organisms.  Many of the sugars regulate host-pathogen interactions and modulate the immune system.  “We want to understand the detailed structures of the sugars associated with disease onset,” said Guttman, “to find new ways of preventing pathogens from infecting cells in the first place, or detecting and targeting cancer cells.”

The current techniques for doing this are somewhat limited, so Dr. Guttman wants to create a novel analytical tool using recent developments in gas-phase structural analysis in combination with existing glycobiology platforms.  “This kind of rapid technology will enable large-scale studies to better understand how various sugar structures regulate the immune response and modulate tumor progression,” said Guttman.  “It will also provide a new way to characterize the next generation of biotherapeutics.”  He added, “I’m grateful to receive the RRF award that will help us move forward on this project.”

Scott Grimm Scholar and Medicinal Chemistry graduate student Dennis Goulet (Bill Atkins lab) has been awarded the prestigious Magnuson Scholarship for 2017-2018, receiving the $30,000 award on the basis of his outstanding academic performance and potential contributions to research in the health sciences. The scholarship is funded from a $2 million endowment from the Warren G. Magnuson Institute for Biomedical Research and Health Professions Training. The University names six Magnuson Scholars annually, one from each of the health sciences schools. Awardees are selected based on their academic performance and potential contributions to health sciences research.

Dennis joined the Atkins lab in 2014 and was selected as a trainee on the NIH-sponsored Pharmacological Sciences Training Grant. Dr. Atkins noted, “Dennis is certainly deserving of this recognition, and I’m lucky to work with him.” As a Magnuson Scholar, Dennis will focus on how fundamental biophysical properties of proteins are related to their safety and efficacy as therapeutics. “As one example,” said Dennis, “we are trying to understand how binding of antibodies to certain receptors affects their stability in the serum.” Such research could be used to moderate the biological half-life of antibody-based therapeutics, allowing patients to receive IV drugs less frequently, while maintaining an efficacious dose.

“It is such an honor to be selected for this prestigious award,” said Dennis. “I am humbled to be representing Medicinal Chemistry and the School of Pharmacy among such a talented group of scholars.”

Congratulations to Dennis on this awesome award!

Sid Nelson’s legacy lives on in science and collaboration

Busulfan is one of our oldest anticancer drugs. Today, it is often used to prepare a patient’s body for a bone marrow transplant (hematopoietic cell transplant [HCT]) to fight various cancers. Busulfan kills some of the patient’s blood cells to ensure the donor cells will be accepted.

But busulfan is toxic.

The work to mitigate that toxicity has become central in three labs across UWSOP—a collaboration that would have brought cheer to the late Dean Sid Nelson. “Sid was fascinated by the biological and toxicological implications of chemistry,” shared Bill Atkins.

“Busulfan is a ‘goldilocks’ drug. The dosing has to be just right.”
–Jeannine McCune, Professor of Pharmacy

Pharmacy Professor Jeannine McCune
Pharmacy Professor Jeannine McCune

The collaboration began when Pharmacy Professor Jeannine McCune reached out to Bill in Medicinal Chemistry. For twenty years, Jeannine has studied the effects of busulfan on HCT patients to improve its efficacy and lower its toxicity. “ She approached Bill about using metabolomics, a new field that characterizes the small molecule metabolites in biological systems. She asked him to look at the data because of his expertise in the protective molecule glutathione, an antioxidant. (Glutathione is important to busulfan because it is metabolized by the glutathione S-transferases.)

“Sid might have called it ‘strange chemistry.’ Normally when a toxic drug modifies a protein, the drug stays around which makes it toxic—but busulfan modified a protein and then disappeared. It’s really awesome! I kept wondering why no one had studied this before.”
–Bill Atkins, Sid Nelson Endowed Professor of Medicinal Chemistry

Former UWSOP Dean, Sid Nelson
Former UWSOP Dean, Sid Nelson

Bill saw the potential for novel protein modifications. In some classic cases, including examples studied by Sid, drugs or their metabolites are toxic because they stick on to proteins covalently. But with busulfan, it reacts with the proteins, changes them, and then disappears—having changed the chemical nature of the protein. “To my knowledge, it’s unprecedented,” said Bill.

Busulfan converts cysteines in proteins into dehydroalanine. These reactions also may have utility in protein engineering or nanotechnology. “If you could get other things to react with the dehydroalanine, you could expand how proteins are used—including application of functional probes, drugs, or targeting moieties.”

“Busulfan is a legacy drug, with a mechanism of action based on World War I chemical warfare agents, but it’s still a frontline drug in pediatric cancer therapy,”
— Ed Kelly, Associate Professor of Pharmaceutics

Associate Professor of Pharmaceutics Ed Kelly
Associate Professor of Pharmaceutics Ed Kelly

The collaboration has expanded. Understanding the toxicity of busulfan led Jeannine and Bill to Ed Kelly in Pharmaceutics, whose work with the organ on a chip project is making him a leader in Toxicology. Ed is working to create a liver on a chip that integrates vascular cells so they can start identifying pathways, proteomics, metabolomics, and chemistry, specifically for busulfan toxicity in this example.

Jeannine, Bill, and Yvonne Lin (Associate Professor in Pharmaceutics) have an ongoing NIH R01 grant trying to improve the efficacy and lower the toxicity of busulfan. The team is eager to continue this project which embodies the collaborative spirit and science that were hallmarks of Sid’s leadership.

Lee lab uses 3D electron microscopy to visualize influenza virus invasion

For the first time, researchers have images showing how a virus pries its way past host membranes

Three to five million people worldwide suffer from the flu each year—and it’s deadly. The World Health Organization (WHO) estimates that 250,000 to 500,000 people a year die from the flu. The people most at risk are those with compromised immune systems: children, older adults, people with immunosuppressive illnesses, and the unvaccinated.

But if you get the flu, those numbers just don’t seem to matter. You feel terrible—like you’ve been slammed by a giant bag of concrete. You lose strength and collapse into bed with fever, chills, aches, pains and more. Your body is all out of sorts. You feel like a zombie. Total dysfunction.

When you have the flu, you are out of sorts—right down to the molecular level.

Thanks to some advanced electron microscopy from UW School of Pharmacy’s Associate Professor of Medicinal Chemistry Kelly Lee’s laboratory, we are starting to understand how the influenza virus aggressively pries its way into cells. The team’s research may eventually lead to improvements in prevention and treatments for the flu and other similar viruses like HIV, herpes, dengue and Zika—diseases that affect millions worldwide every year.

The Journal of Virology published this break-through study in which, for the first time, Lee’s team captured 3-dimensional nanoscopic images of the molecular events that the flu virus carries out in order to fuse itself with a host cell and start a new infection. To create the 3D images, the team is riding a wave of new applications of cryo-electron microscopy (cryo-EM). These powerful electron microscopes, and the next generation cameras they use, are making it possible to obtain unprecedented glimpses into structures of protein machinery and viruses.

They take the protein and virus in a buffer and without fixing or staining the specimen, flash freeze it by plunging the specimen into cryogenic liquid ethane. With that kind of cold, the sample freezes before the water can crystallize, which preserves the proteins and membranes in their native states. Like in an X-ray CAT scan, they tilt the samples to get different views of the viruses undergoing fusion and then use powerful computational methods to reconstruct the 3-dimensional image.

Flu viruses are “enveloped” viruses, and like HIV, herpes, dengue and the Zika viruses, they have a lipid membrane that protects their genetic material. To deliver its genome into cells, the virus needs to merge this membrane “envelope” with the host’s cellular membrane. With better insight into the mechanics of this process, researchers may gain an understanding of how to interfere with this stage of cell entry and prevent infection. Indeed, antibodies produced by our immune systems target and in some cases jam the protein machinery that viruses use to gain entry into cells.

How the influenza virus engages with membranes as it would in infecting a host cell

Flu viruses are covered in spikes. Their external membranes are decorated with fusion protein, known as “spike complexes”— because they look just like that – little spikes arrayed across the virus’ surface. As the virus makes its way through your body, those spikes make contact with healthy cells. They grapple onto the membrane of the healthy cell (or target) and then draw the target membrane towards the virus, creating a dimple in the target surface. The spikes then attach, or pinch, the membrane and draw it closer to the virus, not unlike a tractor beam out of science fiction. When the target membrane is pulled tight, or docked, to the surface of the virus, there is a fusion that happens between the cell’s membrane and the virus’ membrane. These cell and viral leaflets join together to open a channel through which the virus delivers its genome to the cell.

This breakthrough study allowed the team to look at the different stages of the membrane fusion event and figure out the sequence in which they occur. Prior to this, “The field had a lot of indirect information from lower resolution techniques but now for the first time we are able to look at these processes at pretty high resolution and see the proteins, the membranes and how they become contorted and remodeled as the virus carries out membrane fusion. Most of the structures we see for membranes and how they get deformed are somewhat unexpected. It’s surprising and exciting when you see how these events are taking place at the molecular level,” said Lee.

The team’s research continues. “We hope go further in our research with enveloped viruses and are working with other departments to bring more electron microscopy resources to the UW,” shared Lee. “There is strong demand among researchers in many areas of biological sciences to use these types of microscopes and harness their capabilities to help us understand cellular processes at the nanoscopic level.” Beyond enveloped viruses, membrane fusion also is at the heart of basic cell biology and is a critical step in sperm-egg fertilization and signaling across nerve synapses, for example. The Lee lab hopes that their work on the influenza virus case may also help to improve the understanding of these fundamental functions in the life of cells.

Professor and Dean Emeritus Thomas Baillie announces retirement from UWSOP

Professor and Dean Emeritus Thomas Baillie
Professor and Dean Emeritus Thomas Baillie

Dr. Thomas Baillie, Professor of Medicinal Chemistry and Dean Emeritus for the UW School of Pharmacy, has announced that he will be officially retiring from the University of Washington in March of 2016. Tom has had an enormous positive impact on the School of Pharmacy. He has been a tireless and highly effective advocate for our research, teaching and training missions within the School, UW, and across industry. Over the years, he has been a strong mentor and keen supporter of our faculty, students, trainees and alumni. Tom’s leadership and organizational skills were crucial to the continued success of our school during the financial austerity imposed by the recession of 2008. He led us through a difficult curricular revision process triggered by major changes in accreditation standards that ultimately led to full accreditation for the school.

Tom Baillie joined the faculty of the Department of Medicinal Chemistry in 1981. He conducted a vigorous NIH funded research program in mass spectrometry, biochemical reaction mechanisms and toxicity. In 1994, Tom accepted an opportunity to join Merck & Co. as the Executive Director of Preclinical Drug Metabolism in West Point. He rose through the ranks at Merck where he was awarded the position of Vice President and Global Head of Drug Metabolism and Pharmacokinetics. A key member of Merck leadership team, he was also responsible for a group of 350 scientists and staff spread over multiple locations worldwide. While at Merck, Tom maintained strong ties to the school and faculty and fostered close relations between the two institutions. In 2008, he and his wife Kathleen returned to Seattle when he was appointed Dean of the School of Pharmacy and Professor of Medicinal Chemistry. During his tenure as Dean, Tom served as Chair of the Board of Health Sciences Deans and Vice Provost for Strategic Initiatives at the University of Washington. Having seen the School through the economic crisis and our successful reaccreditation, he stepped down as Dean at the end of his term in 2014 and returned to a full time appointment in the Department of Medicinal Chemistry.

UW School of Pharmacy and UW Medicine bring population and basic science together for novel approach to drug research

Heart disease remains a leading cause of death in the United States. While there have been advances in treatments, it is hard to know if someone is at risk for a heart attack until they show symptoms—which for many is too late. Researchers at the UW School of Pharmacy (UWSOP) and UW Medicine’s Cardiovascular Health Research Unit (CHRU) hope to change that.

Rheem Totah, Associate Professor in UWSOP’s Department of Medicinal Chemistry, is the co-lead investigator on two NIH funded grants totaling almost $6M with faculty from CHRU. Totah and Nona Sotoodehnia MD MPH (Cardiology) will co-lead “CYP2J2 Mediated Eicosanoids in Arrhythmias and Sudden Cardiac Arrest.” Totah and Rozenn Lemaitre PhD MPH (Internal Medicine) will co-lead “Epoxyeicosatrienoic acids, diabetes, and cardiovascular disease.”

Nona Sotoodehnia, MD MPH, Co-Director, CHRU
Nona Sotoodehnia, MD, MPH, Co-Director, CHRU

Collectively, these two grants will provide comprehensive information on the epidemiology of epoxyeicosatrienoic acids (EETs) in three large National Heart, Lung, and Blood Institute of the National Institutes of Health (NHLBI-NIH) funded prospective studies, including association with cardiovascular and cardiometabolic disease outcomes. The projects will additionally investigate the molecular mechanism of EETs protection, discover pathways that regulate EET biosynthesis in cardiac tissue, and identify EETs-related pathways affected by diabetes, with the ultimate aim of identifying a novel, potentially modifiable drug targets to improve cardiovascular health.

“These grants perfectly merge population and basic science so that we can comprehensively elucidate the role of EETs in cardiovascular disease and diabetes complications,” said Totah. “The two grants were high risk-high reward and we are excited that they were selected for funding.”

The first study, with Totah and Sotoodehnia, brings together population and basic science to identify a possible biomarker to predict and prevent sudden cardiac arrest. This step is followed by animal and cellular work to determine druggable pathways affecting EET biosynthesis. Using a novel approach, Totah’s team identified a possible marker that could indicate whether or not someone has a higher risk of sudden cardiac arrest.

Rozenn Lemaitre, PhD, MPH, Research Associate Professor
Rozenn Lemaitre, Ph.D., MPH, Research Associate Professor

The second grant, with Totah and Lemaitre, will look at EETs in patients with diabetes to determine the relationship between EETs and cardiovascular disease in this population. Lower levels of EETs may be associated with increased risk of cardiovascular disease in type II diabetes patients. The investigators will also investigate the regulation of various pathways related to CYP2J2 metabolism of arachidonic acid under the stress of diabetes in human cardiomyocytes.

Totah is passionate about translational research and the opportunity to directly affect human health. “Being at the UW School of Pharmacy which is co-located with the UW Medical Center, and the unique collaborative atmosphere in UW Health Sciences allows us to do work that will make a difference in people’s lives,” she extolled.

Research reported in this press release was supported by National Heart, Lung, and Blood Institute of the National Institutes of Health (NHLBI-NIH) under award numbers R01RHL128709 (CYP2J2 Mediated Eicosanoids in Arrhythmias and Sudden Cardiac Arrest) and R01RHL130880 (Epoxyeicosatrienoic acids, diabetes, and cardiovascular disease). The content is solely the responsibility of the authors and does not necessarily represent the official views of the National Institutes of Health.

Kelly Hines Named USP Global Fellow

Kelly HinesKelly M. Hines, Ph.D., senior fellow in the Department of Medicinal Chemistry (Libin Xu lab), is one of three recipients of the 2015-2016 Global Fellowship by the United States Pharmacopeial Convention (USP). This award, in the amount of $30,000, will support Dr. Hines’s project, using Ion Mobility-Mass Spectrometry (IM-MS) to screen standards of approximately 2,000 drug compounds available from the UW and create a database of drug purity information.

IM-MS is a rapid and orthoganal gas-phase separation technique based on molecular structures, requiring only milliseconds per analysis. The technique thus has several advantages over conventional liquid chromatography-based UV or MS methods: its rapid separation nature and determination of the structural information at the same time. Dr. Hines plans to use this technique to define the structure-mass relationship of drugs, excipients (extra material combined with the drug — e.g., to make a pill) and impurities, which would provide high-confidence identifications and purity assessments of drugs (including dietary supplements).

The USP is a scientific nonprofit organization that sets standards for the identity, strength, quality, and purity of medicines, food ingredients, and dietary supplements manufactured, distributed, and consumed worldwide. Dr. Hines’ USP mentor for this project is Shankari Shivaprasad, scientific liaison with USP’s Chemical Medicines Department.

Congratulations, Kelly, on this well-deserved award!

“It’s a micro-farm,” said Allan Rettie recently, talking of the home where he and his wife, Shannon, nurture a menagerie of creatures great and small. “If I was not doing science, I might have been a farmer” he said tongue-in-cheek. But it’s impossible to imagine Rettie “not doing science.” For 30 years he has been at the forefront of what’s happening in drug metabolism and drug interactions. And now he wants to quantify the impact of variants in your genes.

Rettie came to Medicinal Chemistry as a postdoc in 1985, joined the faculty in 1987, and became department chair in 2000. He serves on the editorial boards of scientific journals, NIH grant review panels, and organizations like the International Society for the Study of Xenobiotics. He teaches classes on drug metabolism and organic medicinal agents and runs an expanding research group that has its roots in drug metabolism.

“We plan to create an encyclopedia of gene variations in important drug-metabolizing enzymes that affect drug responses and make it available to the clinical community in an easily accessible format.”
–Allan Rettie

Rettie is currently focused on examining the role genetics plays in drug response, a field called Pharmacogenomics. Some people carry potentially harmful gene variants, and for these people an average drug dose can pose significant health risks.

Consider the commonly prescribed drug warfarin, a “blood thinner” used to treat heart patients and others. The wrong dosage can have a number of negative effects, like excessive bleeding, with disastrous results for patients. Understanding how drug metabolism genes affect the response to warfarin can help health care providers target the dose specifically to individual patients. However, there is currently no easy way for clinicians to know how new gene variants affect treatment with warfarin and other drugs with low safety margins.

With their latest NIH grant, Rettie; Doug Fowler; and colleagues in the UW Department of Genome Sciences aim to create a comprehensive database of drug-metabolizing enzyme variants that affect a patient’s reaction to commonly used drugs. The project, called Functionalization of Variants in Clinically Actionable Pharmacogenes (F-CAP), will catalog the functional effects of all amino acid variation for five important pharmacogenes during the three-year grant period and make the data available to the clinical community in an easily accessible format. “It’s quite ambitious, but we are capitalizing on new, high-throughput experimental approaches that should help us reach the target,” Rettie said.

Perhaps it’s the farmer in Rettie that inclines him to look ahead, even as he grows F-CAP. He is also working on a ‘suicide gene’ system for personalized T-cell applications in cancer therapy. “Collaborators in Germany provide the immunology expertise while we focus on the drug metabolism side of the project.” Finally, Rettie is interested in the genetics of people in historically isolated and underserved populations. “Everyone should be given the opportunity to be included in the precision medicine revolution.”

2015 Summer Diversity Program Wraps

It was a summer of hard work and discovery for four undergrads who participated in the Pharmacological Science Summer Diversity Program (PSSDP).  Hector Caldera (Fort Lewis College), Brianna Morgan (Southern Oregon University), Monica Pengshung (Southern Oregon University), and Hannah Rudolph (Agnes Scott College) recently presented posters at Mary Gates Hall to wrap up their summer experience at the School of Pharmacy.

The PSSDP provides opportunities for talented undergraduate students from diverse social and cultural backgrounds to perform hands-on research in drug metabolism, pharmacokinetics, cellular pharmacology, molecular pharmacology, and biophysical virology.  Participants are selected from a national pool of applicants as well as current UW students.  Those selected receive a stipend, living accommodations, and a transportation allowance for the summer.  The host departments are Medicinal Chemistry, Pharmaceutics, and Pharmacology.

Monica Pengshun rotated with Professor Joanne Wang in Pharmaceutics. Her poster, “Substrate-dependent inhibitory effect of cimetidine and pyrimethamine on renal organic cation transporters OCT2 and MATE1,” focused on predicting drug-drug interactions that could alter the clearance of drugs and toxins from the kidneys.

Hector Caldera collected medicinal plants as a child, sparking an interest in chemistry.  “My summer project took me out of my comfort zone, from organic chemistry to molecular biology,” said Hector.  His poster, “Investigation of the Structure of Recombinantly Expressed Influenza M1 Matrix Protein,” reflects his research into a protein that plays a key role in the life cycle of the influenza virus.  Discovering how to disrupt the protein’s function could lead to new drug designs in the ongoing war against  influenza.  Hector’s faculty mentor was Medicinal Chemistry Associate Professor Kelly Lee.  “I really enjoyed the mixture of support and independence from my mentors,” said Hector. “But . . . I don’t know about being down in that basement.”

Brianna Morgan is a pre-med student and new to the lab environment.  “This experience opened my eyes about grad school and options I might not have had before,” said Brianna.  “It was a supportive team experience for me, and I learned new techniques for research.”  Her poster, “Inhibition of the Cholesterol Biosynthetic Pathway by Known Drugs,” discusses how certain drugs can interrupt the cholesterol biosynthesis pathway.  This inhibition effect may be a risk factor for neurodevelopmental disorders, such as autism, because cholesterol plays important roles in the development of the nervous system.  Brianna’s faculty mentor was Medicinal Chemistry Assistant Professor Libin Xu.

Hannah Rudolph rotated with Associate Professor Paul Phillips in Pharmacology.  We wish our 2015 Summer Diversity students all the best as they begin Fall Quarter in their respective colleges and universities!

Benhaim Appointed to Molecular Biophysics Training Program

Mark Benhaim

Medicinal Chemistry graduate student Mark Benhaim (Lee lab) has been accepted into the NIH-supported Molecular Biophysics Training Program.  His proposed research thesis, “Deciphering the Antiviral Activity of Human Defensins: Inhibiting Influenza Virus Fusion,” won him a two-year tenure on this predoctoral training grant. Benhaim’s mentor, Med Chem Associate Professor Kelly Lee, will fund the research on this project and NIH will pay Benhaim a stipend, partial tuition, and a travel award.

Benhaim successfully completed a rigorous application process including a written research proposal and an interview during which he presented his proposal and answered questions.

Working in the Lee lab, Benhaim is studying how components of the innate immune system recognize and interact with enveloped viruses, specifically influenza virus. The innate immune system is the body’s first line of defense against infection. “My goal is to understand how these defensins, these small antimicrobial peptides, interact with viruses,” said Mark. “We know they prevent infections of diverse viruses like herpes simplex, influenza, and HIV, but very little is understood about how they work.”

The thrill of figuring out how things work is what brought Benhaim to science, and now into biophysics. “These proteins are such amazing molecular machines,” he said. “It just blows my mind how something so small is able to carry out such complex processes.”

“Mark’s studies will provide new mechanistic insight into the action of these important anti-pathogen components of our immune system,” said Dr. Kelly Lee, “and may eventually suggest new strategies for developing antiviral therapeutics.”

Congratulations, Mark!

Med Chem Student Interns with Janssen Pharmaceuticals

Dennis Goulet
Dennis Goulet visits the Liberty Bell in Philly

Dennis Goulet (Atkins lab), graduate student in Medicinal Chemistry, is completing a summer internship with Janssen Pharmaceuticals, Inc., a Johnson & Johnson company headquartered in New Jersey. Janssen wanted someone with a background in biophysical characterization and an interest in antibody scaffolds (proteins that bring other proteins together for interaction); Goulet was selected via application and phone interview. The 13-week internship allows him to see pharmaceutical research from an industry perspective. “It’s fascinating to hear about the research people are working on, and to know any of these projects could produce a new agent to treat cancer and other diseases,” said Dennis.

At the Janssen research facility near Philadelphia, Pennsylvania, Goulet is making antibody constructs and labeling them for use in fluorescence experiments. “We’re interested in the advantages bispecific antibodies may have over traditional monoclonal antibodies for treating cancer,” said Dennis. (Bispecific antibodies are artificial proteins engineered to bind to two distinct biological targets.) By exploring the kinetics and thermodynamics of bispecific antibody assembly, scientists hope to speed up their formation and increase production efficiency to yield more antibodies for therapeutic use.

“It’s quite a collaborative environment,” said Dennis. What surprised him most was the level of support for novel ideas and perspectives. The wide range of scientific backgrounds at Janssen has made it possible for Goulet to explore new techniques and receive advice from experts in the field.

“I’m grateful to Dr. Atkins and Dr. Chiu (Associate Director at Janssen) for giving me this opportunity,” said Dennis, “and to the group at Janssen for making the internship such an informative and enjoyable experience.”

Congratulations, Dennis — see you in Seattle for Fall Quarter!

Med Chem Student Receives Barnes Fellowship

Graduate student Mavis Li Medicinal Chemistry graduate student Mavis Li (Atkins lab) has received an award from the Hope Barnes Fellowship Fund. Hope Barnes was a Med Chem graduate student who died in a climbing accident in 1991. Hope’s family established The Hope Barnes Graduate Fellowship to support and encourage talented graduate students in medicinal chemistry. The Fund will pay Mavis’s stipend and tuition for summer and fall quarters 2015, in addition to a $1,000 recognition award.

Working in the Bill Atkins lab, Mavis is researching the structure and functions of p-glycoprotein (P-gp), a protein which acts as a drug transporter, pumping drugs out of cells in the body. Not enough is understood about the effect of P-gp on the bioavailability and effectiveness of certain drugs.

“I am grateful to benefit from the generosity of Hope Barnes’s family,” said Mavis. “This award will support my work with P-gp and how it affects the behavior of some important drugs that patients rely on.”

Congratulations, Mavis!

Med Chem Group Attends P450 Conference in Japan

Med Chem P450 Conference Attendees
L-R: Wynton McClary, Ryan Seguin, Nick Treuheit, Allan Rettie, Robert Pelletier, Eric Evangelista attend P450 Conference at National Olympics Memorial Youth Center in Tokyo, Japan

Cytochrome P450 enzymes are found in all living organisms and are essential in metabolizing a wide range of substances including steroids, fatty acids and the majority of pharmaceuticals. They control the elimination of most drugs and therefore strongly influence drug-drug interactions that can cause adverse side effects. P450s are also capable of detoxifying many environmental pollutants. In 1976, a small group of scientists gathered to share research about the mysterious enzyme at the center of all this biological action and reaction.

That informal gathering evolved to become the International Conference on Cytochrome P450 (CYP), a major bi-annual event with speakers from all over the world and an expanding range of subjects from basic biophysical research to applied aspects of toxicology and drug metabolism. The Medicinal Chemistry Department, led by professors Allan Rettie and Bill Atkins, hosted the Seattle conference in 2013. Drs. Rettie and Atkins also serve on the conference advisory committee.

Dr. Rettie and five students from Med Chem attended the 2015 conference in Tokyo, Japan earlier this summer. Eric Evangelista, Wynton McClary, Robert Pelletier, Ryan Seguin, and Nick Treuheit presented posters at the conference where Dr. Rettie was a featured speaker (“Drug Metabolism Contributions to the Development of Precision Medicine.”)

“Everyone at the conference was hospitable and welcoming,” said Nick Treuheit. “We got to interact with well-known people in the P450 field and experience the full range of experimentation that’s being done with it.”

“It was a terrific experience to talk with fellow P450 researchers from around the world,” said Ryan Seguin. Ryan was impressed by the variety and breadth of topics covered by the presenters. “Japan is an amazing place,” he added. “I enjoyed interacting with people and experiencing their culture.” Ryan tried local delicacies such as naga-imo (a slimy-textured grated mountain yam) and lived to tell about it, saying “it actually tastes pretty good, once you get past the texture.”

Robert Pelletier was excited to learn about a new way to “see enzymes work” using neutron crystallography, a technique which will play an important role in future drug development. He also enjoyed catching up with old friends and making new friends among the international students.

“It was fantastic hearing about the latest advances in our understanding of Cytochrome P450s,” said Wynton McClary. “And in our spare time we enjoyed Tokyo’s history and atmosphere.” Eric Evangelista agreed it was “a great learning opportunity, meeting with other scientists and discussing their research.”

The students also got helpful feedback on their own work during poster presentations. Ryan presented a new metabolite that may shed light on the metabolism of drugs that contain nitrogen. Robert’s poster dealt with the metabolism of Chlormethiazole, a drug used to treat acute alcohol withdrawal, and its effect on Cytochrome P450 enzyme activity in patients using the drug.

“The P450 conference was an illuminating experience for faculty and students alike,” said Dr. Rettie. “We are all looking forward to the 2017 conference in Dusseldorf, Germany.”

Maldonato wins TL1 research grant

Ben MaldonatoBen Maldonato is busier than usual this summer. The Medicinal Chemistry grad student is one of the 2015 cohort of predoctoral students chosen to receive a summer TL1 grant from the Institute of Translational Health Sciences (ITHS). During this 3-month research experience, Ben is conducting independent research with faculty mentor Rheem Totah, attending an Interdisciplinary Clinical Research Methods Seminar, and participating in colloquia and informal gatherings throughout the UW health sciences community. He will generate a research abstract from his chosen project.

“I’m pretty new to the grant writing process, so I was surprised and excited to be selected,” said Ben.

The TL1 Predoctoral Multidisciplinary Clinical Research Summer Program is an expression of ITHS’s focus on moving scientific discovery quickly to its practical application in clinical and community settings. Participants receive a stipend, tuition for the seminar, and up to $400 for research expenses.

Ben’s research project involves the enzyme Thiol Methyltransferase (TMT), known to metabolize drugs such as Clopidogrel and Prasugrel (blood thinners), among others. Inconsistency in TMT activity may be the key to discovering the reason for the variety in adverse side effects observed when different people are given the same dosage of the drug.

“It’s a great feeling when your research idea is supported with an award,” said Ben. “I’m really grateful for this chance to work with Dr. Totah on research that could help reduce side effects for people who are using these types of drugs.”

Ben’s faculty mentor, Rheem Totah (Associate Professor of Medicinal Chemistry), commented, “I’m pleased to be working with Ben on this project. The goal of the TL1 program is to train clinician-scientists who can translate scientific discovery into practice more rapidly, for the benefit of patients in the northwest U.S. I know Ben will make the most of this opportunity and will have an impact on the field in the future.”

Congratulations, Ben, on this well-deserved honor!

In a basement lab deep within the Magnuson Health Sciences Building, a group of scientists works to decode the mysteries of two deadly viruses: influenza and HIV. Led by Kelly Lee, assistant professor of medicinal chemistry in the School of Pharmacy, they examine the viral fusion proteins found on the outside of “enveloped viruses” – viruses with membranes.

Kelly Lee is an assistant professor of medicinal chemistry in the School of Pharmacy. These proteins activate the fusion of disease-causing pathogens and host cells. During fusion, enveloped viruses merge their membranes with those of host cells to penetrate, and infect, the cell.

“We know how the proteins look before they carry out their function,” Lee said, “but we need to understand the structural changes that occur during fusion.”

By doing so, the lab hopes to develop more effective vaccines that will work with the body’s immune system to recognize and neutralize the harmful viruses.

Pelletier Wins AFPE Award to Study Acetaminophen Toxicity

Robert Pelletier left a career in industry to pursue his PhD in Medicinal Chemistry and follow his passion for teaching and research. The American Foundation for Pharmaceutical Education (AFPE) has recognized Pelletier’s potential for leadership, and awarded him their 2015 Pre-Doctoral Award in Pharmaceutical Science. The award period begins in September 2015. The stipend of $10,000 will support Pelletier’s research for his thesis project, “Mechanism of CYP2E1 Inhibition by Chlormethiazole.”

CYP2E1 is responsible for the metabolism of certain chemical compounds (i.e., as drugs or pesticides) that are toxic to humans. For example, CYP2E1 bioactivates the over-the-counter drug, acetaminophen, to a reactive, toxic metabolite called NAPQI. During an overdose, the amount of NAPQI formed overwhelms the liver, increasing the likelihood of liver damage or liver failure. Acetaminophen toxicity has replaced viral hepatitis as the most common cause of acute liver failure, according to a June 24, 2014 article in Medscape online.

Pelletier is examining chlormethiazole’s suitability as an inhibitor of CYP2E1’s ability to cause these toxic reactions. “We will be able to assess the application of chlormethiazole-mediated CYP2E1 inhibition in preclinical drug development,” notes Pelletier, “and in the possible mitigation of CYP2E1 bioactivation-mediated toxicity, such as that seen with acetaminophen overdose.”

Pelletier, a member of the Kunze Lab, submitted a research proposal to AFPE, along with recommendation letters and a Statement of Purpose. Reviewers were impressed with his extensive research experience, lab skills, and the soundness and relevance of the CYP2E1 project. “I’m so excited to receive this award,” said Pelletier. “I hope my work will lead to advances in addressing the growing issue of acetaminophen toxicity.”

Congratulations to Robert on this well-deserved award!

Klarissa Hardy Receives Major NIH Grant

KlarissaHardy

Congratulations to former UW School of Pharmacy Department of Medicinal Chemistry post-doctoral fellow, Klarissa Hardy, who received a $660,000 National Institutes of Health (NIH) grant to fight breast cancer! Hardy worked with Dean Sidney Nelson to study the affects of the anti-cancer drug lapatinib on the liver. “I learned a lot from Dr. Nelson, from his previous work and experience in this area.”

Dr. Hardy, now a researcher and assistant professor of pharmaceutical sciences at Lipscomb University, made history in receiving the first NIH grant for Lipscomb, and the largest research grant in the university’s history.

Hardy was part of the late Dr. Sid Nelson’s lab at Med Chem, where she studied the targeted breast cancer drug, lapatinib, to examine the role of cytochrome P450-mediated metabolic activation in the liver toxicity associated with lapatinib. “We examined how the liver metabolizes lapatinib and how the products formed from this process might be linked to the toxic effects of the drug on the liver,” she said.

Her current research is aimed at discovering genetic factors, such as metabolism, that may contribute to a patient’s risk of developing a toxic reaction to the drug, thereby limiting its use in certain patient populations. The goal is to improve the safety of the drug and discover ways to minimize toxic reactions.

“The Medicinal Chemistry Department at the UW School of Pharmacy is where all this work started,” said Klarissa.  “I thank everyone in Med Chem for their support and helpful contributions along the way.  I am especially grateful to my mentors, Dr. Allan Rettie and Dr. Sid Nelson, for their guidance, and to Dr. Michelle Wahlin for all of her work on the project during her graduate studies.”

Dean Emeritus Baillie Is Top Cited Researcher

Dean Emeritus Baillie
Dean Emeritus Baillie

Dean Emeritus Thomas Baillie was recognized as one of the topmost cited researchers in the area of Pharmacology & Toxicology. The Thompson Reuters Highly Cited Researchers list identifies over three thousand researchers worldwide whose research was among the top 1% most cited for their subject field and year of publication. Baillie’s research focused on understanding the biochemical mechanisms involved in the metabolism of drugs to chemically reactive metabolites (“metabolic activation”). Many such reactive intermediates are toxic to the cells they encounter, and by gaining knowledge of the identities of these metabolites, it becomes possible to rationally alter the structure of the parent drug to avoid metabolic activation, and thereby design a safer medicine. “Much of this research began at UW when I was a faculty member before I went to the private sector,” said Baillie. “I collaborated with many colleagues here on this work, most especially Sid Nelson.”

Dr. Allan Rettie Steps Down as Chair

AllanRettie

Dr. Allan Rettie has decided to step down as Chair of the Department of Medicinal Chemistry, effective June 13, 2014, after serving the School for almost 15 years in that capacity. During this period, Dr. Rettie has effectively guided the department through many curricular and organizational changes, as well as economic challenges. “It is to his credit that Medicinal Chemistry is in as strong a position as it is today,” said Dean Thomas Baillie.

Dr. Rettie obtained a PhD in Pharmaceutical Sciences in 1983 from the University of Newcastle-upon-Tyne, England, before moving to Seattle to post-doc with Drs. Mont Juchau and Dr. Bill Trager at the UW in the areas of extrahepatic drug metabolism and metabolic drug-drug interactions, respectively. He joined the faculty of the UW School of Pharmacy in 1987 and became the Medicinal Chemistry Department Chair in 2000.

Dr. Rettie’s research interests have focused mainly on the human P450 enzymes and attempts to understand mechanisms of catalysis, substrate specificity, pharmacogenetic variability and adverse drug reactions related to these monooxygenases. He has published over 150 peer-reviewed papers and held research grants from the National Institutes of Health (NIH) in these topic areas for 24 years. Dr. Rettie has served on the editorial boards of Drug Metabolism and Disposition, Drug Metabolism Reviews, Journal of Pharmacology and Therapeutics, Current Drug Metabolism, and Chemico-Biological Interactions, as well as numerous NIH grant review panels.

Dr. Rettie will return to a regular faculty position this summer. “It has been a pleasure working with Allan as a member of the School’s Executive Committee,” said Dean Baillie. “I am grateful for his leadership and I hope everyone will join me in thanking him for his service as Chair.”

Bill Atkins and the Legacy of Sid Nelson

bill-atkinsDr. William Atkins has been named the first Sid Nelson Endowed Professor in Medicinal Chemistry. Bill joined the Med Chem faculty in 1991. His research focuses on the biochemical nature of detoxification enzymes and on drug metabolism, with emphasis on biophysical mechanisms. He has been awarded several NIH grants for his research on enzyme systems. His lab also focuses on characterization of nanoparticles for drug delivery and targeted therapy.

“I am honored to receive this professorship, which is really a tribute to Sid’s life and work,” said Bill with typical modesty. “I hope our work in the lab will be a credit to his legacy.”

Sid Nelson was Dean Emeritus of the School of Pharmacy, and a Professor of Medicinal Chemistry. He passed away suddenly in December 2011. The Sid Nelson Memorial Fund, an expression of both grief and regard for Sid, was built with contributions from family, friends, colleagues, together with donations from private industry. The memorial fund later became the Nelson Endowed Professorship; Bill, who was a colleague and co-author with Sid over the years, is its inaugural recipient.

Allan Rettie, Professor and Chairman of Medicinal Chemistry, said: “This is the first named Professorship in the Department of Medicinal Chemistry. That’s an exciting development for us, and Bill is a most worthy recipient.”

School of Pharmacy Dean Tom Baillie said of Bill, “He possesses the devotion to research and education that were the hallmarks of Sid’s career.”

Bill Atkins Named Inaugural Sid Nelson Endowed Professor

Bill_Atkins

In a fitting tribute to our late colleague, mentor and friend, the School of Pharmacy is humbled to share that we have formally established the Sid Nelson Endowed Professorship in Drug Metabolism. The seeds for the professorship were sown in December 2011, after our much-loved professor of medicinal chemistry and dean emeritus passed away suddenly. Our community rallied together to honor Sid’s life and contributions to the School by creating the Sid Nelson Memorial Fund. The memorial fund later became the Endowed Nelson Professorship — a fund that we hope to eventually turn into a more substantial endowed fund in honor of Sid.

The recipient of this professorship is a distinguished faculty member in the field of drug metabolism — Professor of Medicinal Chemistry Bill Atkins (pictured at left). Bill Atkins earned his bachelor’s in chemistry with honors from The College of William & Mary, his master’s in pharmacology from Harvard University and his PhD in biochemistry from the University of Illinois at Urbana-Champaign. From 1988 to 1991, he performed postdoctoral research in the Department of Chemistry at The Pennsylvania State University as a National Institutes of Health Kirschstein Fellow.

He has been on our Department of Medicinal Chemistry faculty since 1991. His research focuses on the biochemical nature of detoxification enzymes and on drug metabolism, with emphasis on biophysical mechanisms. He has been awarded NIH grants for research on several enzyme systems. Recent research also includes characterization of nanoparticles for drug delivery and targeted therapy.

“This is the first named professorship to be established in the Department of Medicinal Chemistry,” said Dean Tom Baillie. “I am delighted that we can pay tribute to Sid in this way thanks to the generosity of our donors.”

Baillie also notes that Atkins, who was a colleague of and co-author with Nelson for two decades, will carry on Nelson’s legacy well. He possesses the devotion to research and education that were hallmarks of Sid’s career. For his part, Bill Atkins is honored to be the inaugural recipient of this professorship that pays tribute to the life and work of a friend who we all miss deeply.

Kelly Lee Receives NIH Grant to Study Influenza Virus

leelab_web

The Lee lab, L-R: Long Gui, Mike Guttman, Natalie Garcia, and Tad Davenport, discuss membrane fusion at a recent conference in Whistler, B.C.   Missing: Kelly Lee (or is he??)

Dr. Kelly Lee, Assistant Professor of Medicinal Chemistry, has been awarded a $1.45 million grant from the National Institutes of Health to study some of the more elusive but fundamental aspects of influenza virus membrane fusion. Dr. Lee will focus on determining what drives the fusion process, in addition to the nature of membrane deformations during fusion, which currently is not well understood.

Using electron cryotomography, small-angle X-ray scattering with 3-D shape reconstruction, and Hydrogen-Deuterium exchange with mass spectrometry analysis, the Lee lab will study the interplay between the hemagglutinin fusion protein, the viral matrix layer, and host cell membranes during fusion of the influenza virus with the host. In addition, through a variety of collaborations, the Lee lab is starting to investigate the mechanism of action of small molecule compounds that inhibit the fusion process.

“We’re delighted to have received the NIH support, and look forward to learning a lot about the fundamental physical event, protein-mediated membrane fusion, that underlies cell invasion by an important human pathogen,” said Kelly.

Congratulations to Kelly and the Lee lab on receiving support for this exciting research!

eri2web

Eri Nakatani Awarded Magnuson Scholarship

Med Chem graduate student Eri Nakatani (Carlos Catalano lab) has been awarded the prestigious Magnuson Scholarship for 2012. The University names six Magnuson Scholars annually, one from each of the health sciences schools.  Awardees are selected on the basis of academic performance and potential contributions to health sciences research.

As a Magnuson Scholar, Eri will focus on developing therapeutic nanoparticles derived from viral proteins. Her work involves the incorporation of an HIV-1 surface glycoprotein (gp160) into a water soluble, nanoscale lipid bilayer system (nanodiscs), which might someday be useful as an HIV vaccine. The project is a collaborative one involving the Catalano lab, Dr. Shiu-Lok Hu (Pharmaceutics), and Dr. Bill Atkins (Med Chem).

In addition, Eri is working on the thermodynamic characterization of the bacteriophage lambda capsid maturation process in vitro, under the guidance of Dr. Carlos Catalano, and with assistance from Dr. Kelly Lee (Med Chem). “Lambda virus has utility here as a model system for herpes viruses, but we also hope to use it as a platform for the development of targeted nanoparticles for use in therapeutics and/or diagnostics,” Eri said.

“I am so honored to have received this opportunity to take my research to a new level and broaden my scientific horizons,” said Eri. “I look forward to continuing my work on nanoparticle therapeutics and hope to obtain valuable feedback at conferences I might otherwise have been unable to attend.”

Congratulations, Eri!

Faculty Member’s Spin-Off Looks to Improve Mass Spectrometry

Goodlett_SAWN_image

Last year, the director of the UW School of Pharmacy Mass Spectrometry Center, Dave Goodlett, developed a method to make mass spectrometry research easier. The method, known as Surface Acoustic Wave Nebulization (SAWN), simplifies how researchers introduce nonvolatile compounds — such as proteins, lipids and small molecules like caffeine — into a mass spectrometer for analysis. Historically, researchers working with nonvolatile samples had to choose between methods that are easy to perform or that perform well. The SAWN method (pictured at left) combines ease of use with high performance.

With the help of the UW Center for Commercialization (C4C), Goodlett and Dr. Patrick Langridge-Smith of the University of Edinburgh have formed a company, Deurion LLC, to further develop this technology and make it commercially available. In December, Deurion received a $150,000 National Science Foundation grant to continue its work. This grant builds on a UW C4C Gap Fund of $50,000 that Goodlett received last summer to construct a prototype SAWN device.

UW postdoctoral fellows Scott Edgar and Sung Hwan Yoon, members of the Goodlett Lab, are currently working as scientists with Deurion. Edgar is the manager and senior scientist responsible for managing the commercialization of the SAWN technology. Among other things, he and Yoon are writing an interface and developing the wiring system that will allow scientists to plug their laptop into the mass spectrometer and run the SAWN method from their laptop. They’re also working to increase the sensitivity of the method — detecting smaller and smaller amounts of material.

Surface acoustic wave technology was invented in the 1960s and is used today in applications including electronic filters or sensors. However, the technology for ionizing samples specifically for mass spectrometry is a recent development.

Goodlett’s long-term goal for his company is for the new technology to be adopted by mass spectrometry research centers throughout the country. The SAWN method is so easy to use that practically anyone could master it in a few minutes, according to Goodlett. Improving the performance and ease of mass spectrometry will benefit scientists across disciplines — including in the life sciences, the pharmaceutical industry and homeland defense as well as those working in clinical research.

Mass spectrometers also play an important role in an area of investigation popularized by several TV shows in recent years — crime scene investigation. “Mass spectrometers are constantly seen on crime lab shows,” said Goodlett. “These instruments are used to detect explosives or drugs in someone’s system in a crime scene. If the SAWN method became a standard practice, it could speed up important analysis in a crime lab.”

Goodlett and his team are currently in the process of creating a scientific advisory board for Deurion. In addition, they are applying for a Phase 2 National Science Foundation grant to extend funding for another two years. UW C4C has also secured the intellectual property rights to the SAWN method and filed a patent application.

This is not the first start-up company to have spun off from work conducted at the School of Pharmacy. In the past decade, faculty research has also led to the creation of the Department of Pharmaceutics’ Drug Interaction Database and the Seattle biotech company Impel Neuropharma, co-founded by Professor of Pharmaceutics Rodney Ho and alumnus John Hoekman, PhD, ’10. Further, individual faculty members have made many discoveries over the years that have resulted in intellectual property rights.

While Goodlett is excited about this new undertaking, he’s also realistic about the challenges and unknowns ahead. Regardless, he said, “I am learning a lot. I am also glad that this company is providing such a great opportunity for my postdocs.”

Indeed, postdoctoral fellow Scott Edgar is the principal investigator on the NSF grant.

“This is unusual in academia because universities don’t allow postdocs to write their own grants,” said Goodlett. “But because the grant was on behalf of our company, Scott has been able to successfully write and manage the grant.

Remembering Dean Emeritus Sid Nelson

Special Announcement: Sid Nelson Endowed Professorship Inaugural Recipient Announced
May 6, 2013: Professor of Medicinal Chemistry Bill Atkins is the inaugural Sid Nelson Endowed Professor in Drug Metabolism. The seeds for the professorship were sown in December 2011, after our much-loved dean emeritus passed away. Our community rallied together to honor Sid’s life and contributions to the School by creating the Sid Nelson Memorial Fund. The memorial fund later became the Endowed Nelson Professorship — a fund that we hope to eventually turn into a more substantial endowed fund in honor of Sid. We continue to fundraise for this important fund. Make a gift today.
In addition to the following tribute written by Dean Thomas Baillie, you can also read more about Sid Nelson’s life in the Seattle Times, and the Everett Herald. Please email us if you would like additional information about other ways to honor Sid.

A message from UW School of Pharmacy Dean Thomas Baillie
December 11, 2011

It is with profound sadness that the UW School of Pharmacy announces that Professor of Medicinal Chemistry and Dean Emeritus Sidney “Sid” Nelson passed away suddenly on Friday, December 9th. He was 66 years old.It is hard to put into words the impact that Dr. Sid Nelson had on this School, the University, the scientific community and everyone who knew him.It’s not just about the awards and honors Sid received for his leadership, his teaching and his prolific research — and there were many: Dean of the Year from the American Pharmacists Association – Academy of Student Pharmacists, American Association of Colleges of Pharmacy Volwiler Research Achievement Award, UW Gibaldi Excellence in Teaching Award, UW School of Pharmacy Distinguished Alumnus Award, John J. Abel Award from the American Society of Pharmacology and Experimental Therapeutics, and the Frank R. Blood Award in Toxicology from the Society of Toxicology, to name a few.

Nor is it just about the deep love he had for this School of Pharmacy, his colleagues and our students. Sid was a constant presence at student events, alumni events and industry events over the years. He was an enthusiastic supporter of the people around him — cheering loudly in the audience (along with his wife, Joan) at academic and industry events when our pharmacy students received awards; proudly supporting his Ph.D. students at scientific conferences around the world; regularly nominating his colleagues for prominent scientific honors; sending personal notes to alumni and former classmates when he heard exciting updates about their lives; and giving generously to the School of Pharmacy in the form of scholarships and a fund he and his wife created.

Indeed, there are just too many good things to say about Sid to encapsulate what he meant to all of us. I suppose, when it comes down to it, what we will all miss about him most was his kind spirit. Sid Nelson was a caring, genuine man who made a positive impression on everyone who had the good fortune to know him. The School of Pharmacy is not going to be the same without him. We will all remember his off-color sense of humor, his giant collection of penguin paraphernalia and his enduring authenticity.

Sid himself was an alumnus of the University of Washington School of Pharmacy, graduating in 1968 with a B.S. in pharmacy. He went on to receive a Ph.D. degree in medicinal chemistry from the University of California, San Francisco. He joined the UW School of Pharmacy faculty in 1977.

He was dean of our School from 1994 to 2008. Under his leadership, the School converted from a B.S. degree to an entry-level Doctor of Pharmacy degree program and added a nontraditional approach that enabled existing pharmacists to obtain the Pharm.D. degree. He also evolved the graduate programs and worked tirelessly to expand the School’s faculty. In 2008, he returned full time to his research and teaching activities in the School’s Department of Medicinal Chemistry. In recent years, Sid held an NIH fellowship to conduct research in metabolomics/metabonomics at Imperial College London and he was named a National University of Singapore distinguished professor.

On a personal note, I had known Sid for some 35 years, having first met him at a scientific conference in Europe while he was a fellow at NIH and I was a young faculty member at the University of London. We became good friends and kept in close contact over the years, eventually working together as faculty colleagues in the Department of Medicinal Chemistry at the UW in the 1980s through 1990s. When I returned to the School of Pharmacy in 2008 to take over as dean, I knew I had big shoes to fill, but I also knew that he had left me a remarkable institution that he had played a major role in building — with an exceptional community of faculty, staff, students and alumni.

His death is a major loss to our School, the University of Washington, academic pharmacy nationally, and the global scientific community. It was an honor to know him as an educator, mentor, colleague and friend.

William F. Trager, Ph.D: In Remembrance

By Dean Emeritus Sid Nelson

Professor and Chair Emeritus of Medicinal Chemistry William “Bill” Trager lost his short battle to cancer last month. He was 72 years old.

Bill received his Ph.D. in medicinal chemistry — focusing on conformational analysis and nuclear magnetic resonance — from the University of Washington in 1965 under the supervision of the recently deceased Professor Alain Huitric. Bill went on to do his postdoctoral studies at the Chelsea School of Science and Technology in London, studying alkaloid structures with Sir Arnold Beckett.

In 1967, he joined the faculty of the University of California-San Francisco School of Pharmacy as an assistant professor of medicinal chemistry. While at UCSF, he acted as director of the high-resolution mass spectrometry center. That is where his interest in drug metabolism — which would be the focus of his life’s research — began.

In 1972, Bill was recruited back to the UW School of Pharmacy to be a professor of medicinal chemistry. He was the chair of the department from 1980 to 1983. He also served as an adjunct professor in the UW Department of Chemistry.

Bill was an outstanding, encouraging mentor to 22 graduate students and 12 postdoctoral fellows. I was one of his first graduate students, and I found him to have a quick wit and to be one of the most insightful and enthusiastic scientists I had ever met. He served as my mentor throughout my career. I might have been his administrative boss when I was Dean of the School of Pharmacy, but I continued to seek his sage advice throughout those years.

During his career, Bill published more than 200 research papers and was a co-author of two books. He was internationally renowned for his work on warfarin metabolism and mechanisms of warfarin drug interactions. He also was the principal investigator for nearly 20 years of a National Institutes of Health Program Project Grant for investigating drug interactions. Bill received the Alumnus of the Year Award from the UW School of Pharmacy in 2001, and he remained with the University of Washington until his retirement in 2004.

As an alumnus and emeritus faculty member, Bill stayed active with the School of Pharmacy, its faculty and staff. He and his wife, Caryl, recently created a fund that supports graduate students in medicinal chemistry, and his former graduate students and friends created the Drug Metabolism Endowed Graduate Fellowship in his honor.

As a man who was known for his sense of humor, collegial nature and keen intellect, it is hard to measure the impact he had on all those who worked with him and who had him as an adviser.

Bill was responsible for recruiting Dean Thomas Baillie when he first joined the UW faculty in 1981.

As Tom and I reminisced about Bill recently, Tom shared that when he first met Bill, he was immediately impressed by Bill’s personal warmth and sincerity, and he says he “soon came to know him as an outstanding scientist, a wonderful colleague, a valued mentor, and a kind and compassionate human being.”

He also fondly remembers Bill’s perennially cluttered office and his propensity to dress in casual attire. In fact, he spent much of the 1980s wearing his favorite pale blue sweater.

“Yet,” said Tom, “underlying his casual appearance was an ultra-sharp scientific mind that invariably came up with the key questions that needed to be answered.“

That scientific prowess opened the door for many scholarly appointments throughout his career. Among them, Bill acted as the American editor of the journal Chirality, science adviser to the Seattle district of the Food and Drug Administration, and committee member of the Pharmacological Sciences Review Committee of the National Institutes of General Medical Sciences.

If I were to sum up Bill Trager in a single word, it would be “genuine.” He greeted people with a wonderful smile, and I always felt genuinely welcomed by him no matter what the circumstances. He always spoke of his family, friends, colleagues and students with genuine pride and love.

The School of Pharmacy and the wider research community have lost a brilliant mind and a kind soul. He will be sorely missed.

He is survived by his loving wife of 25 years, Caryl, and seven children from his blended family.

Remembering Alain Huitric

By Bill Trager

Alain Huitric, professor emeritus of medicinal chemistry, passed away in late July at his home in Brittany, France, shortly before his 97th birthday.

Al was born in 1912 in Sainte Rose du Lac, a small French-Canadian community in the province of Manitoba. In his teens, he and his family immigrated to the United States and took up residence in Los Angeles.

He served in the United States Navy during World War II and upon his discharge, he used the G.I. Bill to further his education. He obtained his bachelor of science in chemistry from the University of San Francisco and his Ph.D. in medicinal chemistry from the University of California, San Francisco.

Al joined the faculty of the School of Pharmacy at the UW in 1955 where he remained for the rest of his career, retiring in 1978. He was the first School of Pharmacy faculty member to secure National Institutes of Health funding for research programs.

In the late 1950s and early 1960s, nuclear magnetic resonance was in its infancy. Al recognized its unique potential for solving thorny problems of structural organic chemistry, and it became the primary research tool in the dissertations of virtually all of his Ph.D. students. Training in this state-of-the-art technique opened doors for their further career development.

A quiet and gentle man, he was foremost a man of integrity. Al not only embodied the qualities of integrity — sound moral principles, honesty and sincerity — he exuded them. The power of his integrity commanded respect and had a profound influence on the lives of many, myself and Dean Emeritus Sid Nelson included.

Indeed, Dean Emeritus Nelson credits Al with inspiring him to pursue the path of teaching and research. He also says that, without Al’s “gentle nudge and huge vote of confidence,” he never could have become the dean of the School of Pharmacy.

And so Al’s legacy has been carried on through the many accomplishments of those of us who were his students. This also includes the president and CEO of a Fortune 500 chemical company as well as prominent researchers and professors at major universities.

But perhaps most importantly, his legacy is carried on through so many other people whose lives have been enriched simply by having known him.

Al is survived by his wife, Simone. After being a bachelor for most of his adult life, he met Simone on a trip to Brittany — the birthplace of his parents — in 1963. They soon married and a few years after his retirement, they returned to their roots and settled permanently in Brittany.

Al, we miss you.

Bill Trager received his Ph.D. in medicinal chemistry under the direction of Dr. Huitric at the University of Washington in 1972. He is professor emeritus of medicinal chemistry in the School of Pharmacy, and he served as chair of the department from 1980 to 1983.

Gifts can be made in Dr. Huitric’s honor to the UW School of Pharmacy Dean’s Fund for Excellence. To give, visit this page or contact the School of Pharmacy Office of Advancement at (206) 616-3217, rxgiving@uw.edu

UW School of Pharmacy Ph.D. Research Programs Rank #1

The University of Washington School of Pharmacy medicinal chemistry and pharmaceutical sciences research programs are the best in the nation according to a recent academic ranking. The findings, announced in the January 12 issue of The Chronicle for Higher Education, are based on faculty scholarly activities calculated by The Faculty Scholarly Productivity Index.

The Index looked at 104 programs at top ranked institutions from leading State Universities to elite private and ivy-league schools. The UW School of Pharmacy medicinal chemistry and pharmaceutical science programs ranked at the top despite tough competition.

“This is a well-deserved honor,” said UW School of Pharmacy Dean, Sid Nelson, PhD, “This ranking, the first based on benchmark data, provides a useful metric analysis of the exceptional work of our faculty.”

The Faculty Scholarly Productivity Index partly financed by the State University of New York at Stony Brook and produced by Academic Analytics, a for-profit company, rates faculty members’ scholarly output at nearly 7,300 doctoral programs around the country. It examines the number of book and journal articles published by each program’s faculty, as well as journal citations, awards, honors, and grants received. The Index is being hailed by some in academe for its objective benchmarks, its transparent methodology, and its commitment to regular and predictable reporting. The National Research Council’s rankings of doctoral programs, once the most respected in academe, have not been updated since 1995 and have never included pharmacy research programs in its rankings. Other annual graduate program rankings such as U.S. News & World Report’s have been criticized for years by academics as unscientific popularity contests.

The University of Washington ranked number one in five additional Ph.D. research programs: microbiology, genetics, zoology, business administration, and fisheries science and management.

The University of Washington School of Pharmacy Department of Pharmaceutics has instructional and research programs that emphasize a Physiologically-Based Approach to Drug Delivery and Disposition. This program includes a molecular evaluation of drug delivery, metabolism and transport processes, and the genetic and environmental factors that control enzyme and transporter protein function. The University’s Department of Medicinal Chemistry focuses research in the areas of mechanistic drug metabolism, toxicology, bioanalytical chemistry, molecular modeling, biological mass spectrometry and biological NMR.

UW Hosts 30th National Medicinal Chemistry Symposium

The University of Washington School of Pharmacy was honored to host the 30th National Medicinal Chemistry Symposium from June 25-29 on the UW campus. Over 517 individuals attended the event, most from industry, nearly 15 percent of which came from international organizations.

The four-day Symposium included two poster sessions, seven speaker sessions, an awards ceremony and many additional opportunities for guests to mingle and meet while enjoying the beauty of a Pacific Northwest summer. “Our goal [for the Symposium] was to create a meeting that was interesting scientifically, and to also provide opportunities to meet new scientists and renew old acquaintances,” explained Wendel Nelson, Medicinal Chemistry professor and chair of the event.

The speaker sessions focused on important physiological and therapeutic targets, technological methods and a late breaking session with reports on new drug candidates. Topics included Type 2 diabetes treatment, improving failing memory, microfluidics/nano scale drug discovery, stopping virus entry, sodium channel blockers and late breaking results. George Ellestad, Columbia University alumnus and Wyeth retiree, was awarded the ACS Med Chem Division Award for his work on natural products.

The symposium was a great success and as Medicinal Chemistry chair Allan Rettie described, “One that provided our students and faculty access to cutting edge drug discovery and development practiced in both academic and pharmaceutical industry environments.”

Professor Daggett Wins $2 Million INCITE Award to Further Research on Protein Folding

 

proteinValerie Daggett, professor of medicinal chemistry at UW School of Pharmacy, has received one of three Innovative and Novel Computational Impact on Theory and Experiment (INCITE) awards for her research in “Molecular Dynameomics.” This award, given by the US Department of Energy (DOE) provides Daggett the use of 2 million processor hours on the DOE’s IBM supercomputer housed at the National Energy Research Scientific Computing (NERSC) Center in Berkeley, California, to further her studies in protein folding with the aim of deciphering genetic information.

Daggett’s research focuses on realistic molecular modeling studies relating to protein stability, function, and folding. She and her team of researchers, use computer simulation methods to study the approximately 1,130 known, non-redundant protein folds. Up until this point, her team has been able to simulate about 30 of these folds. The supercomputer, which contains over 6500 processors, will enable Daggett and her team to take their study to a new level. By running the hundreds upon hundreds of slightly different simulations supported by the supercomputer, Daggett will create an extensive repository of molecular dynamics structures for protein folds, including the unfolding pathways. In addition, the control native simulations will be used in drug design studies.

“We are excited about the massive resources to which we now have access,” says Daggett. “The supercomputer will enable us to do in a month and half what would take several lifetimes on a single processor.”

Although much is known of the structural details of the native folded conformation of proteins, very little is known about the actual folding process. An understanding of protein folding has important implications for all biological processes, including protein degradation, protein translocation, aging, and human diseases, including cancer and amyloid diseases. Daggett’s research combined with the computing power of the supercomputer make this award an instrumental step towards advancing our knowledge of how proteins express genetic information and the medical advances such knowledge enables.

Current market value for processing time is $1 per hour. In addition to processing time, award winners will receive technical support and data storage privileges. This translates Daggett’s award in a monetary value of well over $2 million. In addition to the DOE award, Daggett has recently received a $25,000 Microsoft SciData Award for her project Dynameomics: Internet database and Web portal for molecular dynamics simulations of proteins.

UW Professors Identify Genetic Basis for Variation in Patient Response to Warfarin

warfarinDr. Allan Rettie, professor and chair of medicinal chemistry in the UW School of Pharmacy, Dr. Mark Rieder, research assistant professor in genomic sciences and their colleagues have identified a major genetic factor responsible for variability in patient responses to the commonly prescribed coumarin-based anticoagulant known as Warfarin. Warfarin, used to prevent harmful clotting after a heart attack, stroke or major surgery, is thought to be taken by over two million people a day in the US alone, yet dosage needs vary considerably between patients resulting in a challenge for their physicians. Rettie and his colleague’s research, supported by NIH funding, in genetic variation and the relationship this has to drug and dosage needs may enable physicians and pharmacists to more precisely medicate, thereby eliminating the negative effects of over- or under-medication. This field of study, known as Pharmacogenetics, is an important scientific pursuit at the forefront of the advancement of medical care. Read more about Rettie’s research in the June 2, issue of The New England Journal of Medicine or click on NPR interview.
