Dipeptidyl peptidase-IV (DPP-IV) inhibitors are incretin enhancers used in the treatment of diabetes. Due to their undesirable side effects, development of new agents preferably from natural sources with less adverse effects is needed. Apigenin (API), a well known insulin-secretagogue and insulin-mimetic agent is abundantly present in fruits, nuts and plant derived beverages. The present study investigates the DPP-IV inhibitory potential and antidiabetic effects of API using various approaches. Through in silico study, we showed that API has binding efficacy at Glu206 in the active site of DPP-IV. Plasma glucose and insulin levels were decreased when API (1.5 mg/kg b.w. for every alternate for last 30 days) was administered to high fat, high fructose diet (HFFD) fed rats. Further, the activity of DPP-IV in plasma and hippocampal homogenate was inhibited more in the API- treated group than in the sitagliptin (STG)- treated group. API has a strong inhibitory effect towards DPP-IV enzyme in vivo and in silico and therefore can be a promising compound for type 2 diabetes (T2D) treatment.
