P32/98 (hemifumarate) is an inhibitor of DPP IV.
Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide 1 (GLP-1) are responsible for >50% of nutrient-stimulated insulin secretion. After being released into the circulation, GIP and GLP-1 are quickly inactivated by the circulating enzyme dipeptidyl peptidase IV (DPP IV).
In vitro: P32/98 was found to be able to block adipogenesis dose-dependently, starting at the concentration of 100 μM, and P32/98 could completely block adipogenesis in 3T3-L1 cell line at 500 μM concentration. In addition, the inhibitory effects of P32/98 was further confirmed by detecting the expression of adipocyte markers at the end of differentiation [1].
In vivo: In previou animal study, two groups of fa/fa Zucker rats were orally treated twice daily for three months with P32/98 at 20 mg/kg/day and monthly oral glucose tolerance tests (OGTTs) were conducted after drug washout. Results showed that after 12 weeks of P32/98 treatment, the peak OGTT blood glucose values in the treated rats averaged 8.5 mmol/l less than in the controls. In addition, the concomitant insulin resulted in an increased early-phase insulin response in the treated group. Moreover, in response to an 8.8 mmol/l glucose perfusion, pancreata from controls showed no increase in insulin secretion, while pancreata from P32/98-treated animals had a 3.2-fold rise in insulin secretion [2].
Clinical trial: Up to now, P32/98 is still in the preclinical development stage.
