About
Dr. William M. Atkins earned a Masters Degree in Pharmacology from Harvard University in 1983 and a Ph.D. in Biochemistry from the University of Illinois at Urbana-Champaign in 1988. He performed postdoctoral research in the Department of Chemistry at The Pennsylvania State University as an NIH Kirschstein Postdoctoral Fellow from 1988 to 1991. Dr. Atkins has been a faculty member at the University of Washington since 1991 and served as the Sidney D. Nelson Professor and Chair of Medicinal Chemistry from 2016 to 2025. His research focuses on the enzymology of detoxification enzymes and drug metabolism, with particular emphasis on biophysical mechanisms. He has been awarded NIH grants for research on enzyme systems including Cytochrome P450s, Glutathione S-transferases, and the P-glycoprotein efflux transporter. Recent research efforts include the characterization of nanoparticles for drug delivery and therapeutic antibody drug conjugates. Dr. Atkins serves on international conference committees and review panels, and is a member of editorial boards for scientific journals.

Considerations for the Design of Antibody-Based Therapeutics
Journal of Pharmaceutical Sciences · 2019-06-04 · 288 citations
reviewOpen accessSenior authorAntibody-based proteins have become an important class of biologic therapeutics, due in large part to the stability, specificity, and adaptability of the antibody framework. Indeed, antibodies not only have the inherent ability to bind both antigens and endogenous immune receptors but also have proven extremely amenable to protein engineering. Thus, several derivatives of the monoclonal antibody format, including bispecific antibodies, antibody-drug conjugates, and antibody fragments, have demon…
Heme Binding Biguanides Target Cytochrome P450-Dependent Cancer Cell Mitochondria
Cell chemical biology · 2017-09-14 · 52 citations
articleOpen accessJournal of Biological Chemistry · 2018-03-06 · 45 citations
articleOpen accessSenior authorCorrespondingP-glycoprotein (P-gp) is a highly substrate-promiscuous efflux transporter that plays a critical role in drug disposition. P-gp utilizes ATP hydrolysis by nucleotide-binding domains (NBDs) to drive transitions between inward-facing (IF) conformations that bind drugs and outward-facing (OF) conformations that release them to the extracellular solution. However, the details of the protein dynamics within either macroscopic IF or OF conformation remain uncharacterized, and the functional role of lo…
Mechanisms of promiscuity among drug metabolizing enzymes and drug transporters
FEBS Journal · 2019-10-30 · 43 citations
reviewOpen access1st authorCorrespondingDetoxication, or ‘drug‐metabolizing’, enzymes and drug transporters exhibit remarkable substrate promiscuity and catalytic promiscuity. In contrast to substrate‐specific enzymes that participate in defined metabolic pathways, individual detoxication enzymes must cope with substrates of vast structural diversity, including previously unencountered environmental toxins. Presumably, evolution selects for a balance of ‘adequate’ k cat / K M values for a wide range of substrates, rather than optimizi…
Dynamics and Location of the Allosteric Midazolam Site in Cytochrome P4503A4 in Lipid Nanodiscs
Biochemistry · 2020 · 37 citations
Senior authorCorrespondingPromiscuous and allosteric drug interactions with cytochrome P450 3A4 (CYP3A4) are ubiquitous but incompletely understood at the molecular level. A classic allosteric CYP3A4 drug interaction includes the benzodiazepine midazolam (MDZ). MDZ exhibits homotropic and heterotropic allostery when metabolized to 1'-hydroxy and 4-hydroxy metabolites in varying ratios. The combination of hydrogen-deuterium exchange mass spectrometry (HDX-MS) and Gaussian accelerated molecular dynamics (GaMD) simulations…
