About Me

The focus of the Denton Lab is medicinal chemistry, which means we build new therapies (drugs) using chemistry approaches. Think of a drug as a cool sculpture you or your child has built with Legos, tinker toys or in Minecraft. Each sculpture is made up of the same building blocks, but the number of sculptures one can make is nearly endless. This is what we do. We use a sculpture that already has a purpose (like a drug that can relieve symptoms of Alzheimer’s disease), partially take the sculpture apart and rebuild it a little bit differently. Then we test to see if it is better than the original. If it is better, we make sure to record how we did it and then try again, by using the same size bricks but of a different color, etc. or by modifying a different part of the sculpture, etc.

By being “molecular architects,” there really is no limit to the human diseases we can fight. But there is only so much time in the day, and the true passion of the lab is finding a cure for untreatable cancers, neurodegenerative diseases, nicotine addiction, and understudied metabolic disorders.

As for me personally, I was born in Honolulu, Hawaii (Air Force family), moved from there to Vacaville, California, then to Wenatchee, Washington, Tacoma and finally Moses Lake, Washington, where I spent most of my growing up (from third grade on). I went to Peninsula Elementary followed by Frontier Junior High School and graduated from Moses Lake High School. I then went to College at Central Washington University as a pre-med major. But, once I started doing synthetic medicinal chemistry in the lab of John M. Gerdes in the Department of Chemistry, I was hooked! Dr. Gerdes, Mark Walker and I turned a storage lab into the place where I began my journey by making quinolynoylphenylalkylamines as serotonin transport (SERT) inhibitors. Dr. Gerdes is now a Research Associate Professor of Medicinal Chemistry at the University of Montana. GO GRIZ!!!!!!!

After graduating with a Bachelor of Science in Chemistry I moved to the medicinal chemistry lab of Charles M. Thompson at the University of Montana where I learned about the glutamate neurotransmitter system including the complexities of the excitatory, tripartite synapse, glutamate transporters, receptors, synaptic vesicles and the glutamate-glutamine cycle. This is where we described some of the first pyroglutamate analogues as EAAT2 (GLAST) uptake inhibitors and published Synthesis and Preliminary Evaluation of trans-3,4-Conformationally-Restricted Glutamate and Pyroglutamate Analogues as Novel EAAT2 Inhibitors. Additionally, I was trained in organophosphorus chemistry and became affiliated with Dr. Palmer Taylor of University of California San Diego, Dr. Arthur J. L. Cooper, Gary Gibson, and colleagues at the Weill Cornell College of Medicine where we study phosphonate analogues of the TCA cycle in regard to Alzheimer’s disease and glutaminolysis.

After graduate school I did a post-doc with John R. Cashman at the Human Biomolecular Research Institute in San Diego, California. This is where I began researching cytochrome P-450 2A6 (the main nicotine metabolizing enzyme in humans) inhibitors as nicotine cessation agents.

After my second post-doc I moved back to the beautiful state of Washington and took an Assistant Professor position teaching organic chemistry and the general, organic and biological chemistry series for health science majors and training undergraduates in synthetic medicinal chemistry, chemical biology, carbohydrate and polymer chemistry and molecular biology. While at EWU I had a wonderful group of undergraduate students who presented their research more than 85 times at International, national, regional and local meetings. These students are now practicing nurses, pharmacists, medical doctors, doctors of osteopathic medicine, dentists, dental hygienists, post-doctoral fellows, managers in industry (pharmaceutical companies, computational software, etc.) and more! I am very proud of all the brilliant students I was lucky to mentor while they were undergraduates!

I then upgraded to a Clinical Assistant Professor position in the Department of Pharmaceutical Sciences in the College of Pharmacy and Pharmaceutical Sciences at WSU Health Sciences, Spokane. After receiving my first NIH grant, I was promoted to Assistant Professor (tenure track) and have been in this position since.

I have an active research lab and we are always recruiting new talent. If you are in college nearby (Gonzaga, Whitworth, Spokane Community College, Spokane Falls Community College, EWU, etc. I’d love to teach you some chemistry and how to treat devastating diseases of the human body.

I am the instructor of record (IOR) for the second year Doctor of Pharmacy students for PharDSci 547: Drug Discovery and Development as well as the Doctor of Philosophy in Pharmaceutical Sciences and Molecular Medicine students for PharmSci 576: Biophysical Methods. I also am a co-instructor for Dr. Remsberg in Pharmaceutics.

In my spare time I like to…

My wife, Monica, and I love anything with my family! I have a great time watching my son, Taylor, play soccer (premier level for the Spokane Sounders, High School for Cheney High and alternative club for Cheney Storm) and my daughter, Makenna, ride her horses in either 4-H competitions (performance and gaming), open barrel races, play dates, Northwest Pattern Racing Association (NWPRA) or with her Medical Lake Washington High School Equestrian Team (WAHSET)! I also have a great time with our black lab, Dexter, training, running competitive hunting trials and hunting waterfowl and upland birds!

Why WSU?

I grew up in Eastern Washington and always wanted to be a Coug. Now I am!
