A new library of pyrido-pyrrolidine hybrid compounds were designed, developed and screened for their antidiabetic property with α-glucosidase. The design is based on preliminary screening of key fragments identified from literature reported α-glucosidase inhibitors and antidiabetic compounds. The most active fragments were stitched to provide a pyrido-pyrrolidine hybrid molecule as a new motif. A library of these compounds were synthesized and screened against a series of α-glycosidases. Subsequently, compound 3k was the most efficacious analog with IC50 of 0.56 μM. Photoluminescence study and circular dichroism experiments indicated that compound 3k modulates the primary and secondary structure of the enzyme. It successfully brings down the fasting blood glucose level for streptozotocin (STZ, 70 mg/kg, Intraperitoneal) induced type I diabetic male Sprague-Dawley rats (250–320 g). At lower concentration, compound 3k slightly stimulates proliferation of BRIN-BD11 (α-glucose responsive beta cells from rat pancreas islets that secretes insulin) cells.

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.

2-Amino or 2-hydrazino derivatives of pyridine or pyridinopyrazole were obtained by amination or hydrazination of 2-chloro-3-cyano-4-methoxy-6-methylpyridine. Acid hydrolysis of these derivatives leads to heterocyclization with formation of 4-amino-1H-fur
