Title: Merging of Chemistry and Biology: In Search of Molecules with Translational Function K.D. Janda Professor and Ely R. Callaway Chair in Chemistry Director of the Worm Institute of Research and Medicine (WIRM) Departments of Chemistry and Immunology The Scripps Research Institute La Jolla California 92037 USA Abstract: Nature contains information to instruct scientists about what is possible. This can serve as an inspiration to probe the frontiers of biology and chemistry. At the same time, chemistry can contribute to our understanding of biology and also to our ability to manipulate complex systems for human health and welfare. The combination of the tools and principles of chemistry, together with the tools of modern biology, allows us to create complex synthetic and natural molecules, comprising processes with novel biological, chemical and physical properties. This lecture will illustrate the opportunities that lie at this interface of biological chemistry by describing a series of examples that we are actively working on in our laboratory. Including developing vaccines for treating heroin abuse, cell-to-cell communication within bacteria and how some of these quorumsensing molecules display a symbiotic relationship to cancer immunosurveillance as it relates to TRAIL’s apoptotic pathway.
