Alogliptin Benzoate

Alogliptin is a novel, highly selective and potent inhibitor of serine protease dipeptidylpeptidase-4 (DPP-4) with IC50 value of less than 10 nM [1].

Alogliptin has been reported to significantly reduce plasma DPP-4 activity and increase active GLP-1 levels in a dose-dependent manner in ob/ob mice. Besides, alogliptin after 4 weeks administration remarkably reduced non-fasting glycosylated hemoglobin, non-fasting plasma glucose and triglyceride levels, as well as siginificantly increased non-fasting plasma insulin and fasting pancreatic insulin content in ob/ob mice. Moreover, alogliptin treated ob/ob mice have shown the increase of early-phase insulin secretion and the decrease of plasma glucose AUC [2]
