P32/98 is a potent inhibitor of dipeptidyl peptidase IV . P32/98 improves glucose tolerance, insulin sensitivity and β-cell responsiveness in preclinical studies using the fatty Zucker rat, an animal model for IGT (impaired glucose tolerance).

P32/98 (25 mg/kg; i.g.; once daily) long-time treatment significantly improves the glucose tolerance in Zucker diabetic fatty rats[2]. Animal Model: Zucker diabetic fatty rat[2]Dosage: 25 mg/kg Administration: i.g., once daily Result: Significantly improved the glucose tolerance in Zucker diabetic fatty rats.
