Research Interests:

Organic and Medicinal Chemistry -- Total synthesis of biologically active natural products and natural-product based drug discovery.

Our primary research goal is the total chemical synthesis of natural products that are biologically active.  We also seek to develop and use enabling methodology to realize our synthetic goals while emulating nature's likely approach to access complex organic molecules (i.e., biomimetic synthesis).  Toward this end, three of our recent total syntheses, of the selective coagulation factor XIa inhibitor clavatadine A and anti-cancer 1,2,4-oxadiazole-containing alkaloids phidianidine A and B, provided an ideal platform to test our direct guanidinylation approach for the preparation of terminal guaindine containing natural products.  Each molecule we prepare in our laboratory may be developed into a useful tool to study its biological mechanism of action or its biosynthesis from simpler organic compounds.  Further, the development of a versatile, convergent synthetic approach to these intriguing molecular architectures may enable us to prepare non-natural analogues as a starting point for therapeutic development.
Current projects under development in our group include derivitization of clavatadine A to produce analogues that may be potent, selective, and reversible inhibitors of human blood coagulation factor XIa.  If successful, this research may lead to the development of a therapeutic drug to treat or prevent coagulation disorders in persons genetically predisposed to excess blood clotting, a potentially fatal condition known as thrombosis that can cause heart attacks and strokes.
