The research in my group can be summarized as investigations of the molecular mechanisms of action, rational design, and syntheses of potential medicinal agents, particularly for neurodegenerative diseases. Numerous drugs are known to function as specific inhibitors of particular enzymes. When little is known about the enzyme's molecular mechanism of action, chemical model studies are designed to determine reasonable nonenzymatic pathways applicable to the enzyme. Based on the proposed mechanism of enzyme action, inhibitors are designed and synthesized. Organic synthesis is a primary tool for this work. The enzymes are isolated from either mammalian tissue or from overexpressed cells containing recombinant enzymes. Active site labeling studies utilize MALDI TOF and electrospray ionization mass spectrometry as well as radiolabeled inactivators and peptide mapping. We also are synthesizing compounds to act as receptor antagonists for important receptors related to neurodegenerative diseases.
