Vildagliptin (LAF-237) (C007B-306797)

InformationVildagliptin (LAF-237) Vildagliptin (LAF-237) inhibits DPP−4 with IC50 of 2.3 nM.In vitroVildagliptin is the most stable DPP-IV inhibitor, binding in the S1- and S2-catalytic sites of DPP-IV, possessing a P-1 site transition-state mimetic.In vivoVildagliptin(orally dosed with 10 μmol/kg) is a potent, orally active inhibitor of plasma DPP-IV activity that provides increased levels of GLP-1 in an oral glucose tolerance test (OGTT) with Obese male Zucker rats. Vildagliptin orally dosed with 10 μmol/kg both significantly decreases glucose excursions and stimulates insulin secretion in Obese male Zucker rats. Maximum inhibition of plasma DPP-IV activity (95%) is observed approximately 2 hours postdose of Vildagliptin (1 μmol/kg, po) while >50% inhibition of DPP-IV is observed within 30 min postdose and persisted for >10 hours in normal Cynomolgus monkeys. Vildagliptin(60 mg/kg) increases pancreatic beta cell mass through enhanced beta cell replication and reduced apoptosis, and the increased beta cell mass is sustained for 12 days after vildagliptin washout. Vildagliptin administrated at doses of 10 mg/kg for 32 weeks protects nerve fiber loss in streptozotocin (STZ)-induced diabetic adult male Sprague Dawley rats.Cell Datacell lines：MCF7, NCI-H292, Colo-205, HT29, H358, H1703, BxPC3, A673, SW620, DU4475, HepG2 and Hepa-1, RKO 3T3/hulGF-IR and H292 cellsConcentrations：Incubation Time：Powder Purity:≥99%.
