Abstract
Dihydrofuro[3,4-c]pyridinones are the first class of small molecules reported to inhibit the cytolytic effects of the lymphocyte toxin perforin. A lead structure was identified from a high throughput screen, and a series of analogues were designed and prepared to explore structure-activity relationships around the core bicyclic thioxofuropyridinone and pendant furan ring. This resulted in the identification of a submicromolar inhibitor of the perforin-induced lysis of Jurkat T-lymphoma cells.
