Personal profile

Research Interests

The research in Professor Silverman’s group can be summarized as investigations of the molecular mechanisms of action, rational design, and syntheses of potential medicinal agents. The primary focus is basic research into central nervous system disorders, including Parkinson’s disease, cerebral palsy, amyotrophic lateral sclerosis, addiction, and epilepsy. Other therapeutic areas include cancer (melanoma and hepatocellular carcinoma), lysosomal storage diseases, such as Gaucher’s disease, and bacterial infection. Numerous drugs are known to function as specific inhibitors of particular enzymes. For some enzyme targets, where potent reversible inhibitors are desired, computer modeling based on X-ray crystal structures initiates the research (high-throughput screening also may be used). For enzyme targets where inactivators are desired and 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. For those enzymes, mechanism-based inactivators are designed and synthesized and inactivation mechanisms investigated. The enzymes are isolated from either mammalian tissue or from overexpressed cells containing recombinant enzymes. Collaborations are developed in X-ray crystallography and preclinical studies.
