We engage the Portland, Oregon scientific and technical community to enhance the health of the scientific research enterprise, provide opportunities for the next generation of scientists and engineers, and promote the public's understanding of science and technology. We are comprised of faculty and students from several colleges and universities in the Portland area, as well as colleagues in local business, industry, federal and state agencies, and medical centers. We focus many of our programs on enhancing the experiences of students at all levels. Many of our members are retired scientists and engineers who have relocated to the Portland area and find a community of interests through the activities of the chapter.

A Chemist’s Try at Overcoming a
     Very Clever Parasite’s Drug Resistance

This lecture tells the story of how a new type of drug against malaria was discovered, and is being developed. These new drugs are hybrid molecules, made by combining the ‘business-end’ of the old antimalarial drug chloroquine (CQ), with other drugs that are known to inhibit the drug efflux that contributes to drug resistance in many diseases. The resulting ‘resistance-reversed’ drugs can have potencies that can exceed that of the original drug (chloroquine), and have properties that may make them favorable as partners for other drugs to be used in combination therapies. This 'technology platform’ may also be applied to other diseases.

David H. Peyton, Ph.D., is a Professor of Chemistry at Portland State University (at PSU since 1987) and Chief Scientific Officer at DesignMedix, Inc., Portland, OR (founded in 2007). He has worked on many areas of research, from Nuclear Magnetic Resonance (NMR) methods and analytical development, to medicinal chemistry. His work on malaria parasites began in about 1992, with a NMR-based studies of antimalarial drug action. He obtained his B.S. from Abilene Christian University and his Ph.D. from University of California, Santa Barbara, and he did postdoctoral work at Cornell University Medical College and University of California at Davis. He has had the privilege of supervising 13 Ph.D. students, as well as 8 M.S. students, and currently has 4 Ph.D. and 2 M.S. students working in his laboratory. His current grant support includes a National Institutes of Health award to DesignMedix (with a subaward to PSU), to bring a resistance-reversed antimalarial drug against malaria to a Phase-1 clinical trial.



Scott Burns, the VP of this chapter and a recently retired professor of geology at Portland State University, was selected Outstanding Oregon Scientist for 2014 by the Oregon Academy of Science.
