Diabetes mellitus is a chronic disease characterized by hyperglycemia mainly because of the absolute or relative deficiency of insulin hormone. The dipeptidyl peptidase-IV inhibitors represent a class of glucose-lowering agents potentiating the action of the incretin hormones glucagon-likepeptide-1 and glucose dependent insulinotropic polypeptide, which are secreted from the intestinal endocrine cells in response to food ingestion to stimulate insulin secretion from pancreatic beta cells.
Natural products have traditionally been used for curing many diseases. In this study, in vitro biological evaluation of the isolated compounds calotoxin, calotropin, pectolinarigenin, apigenin7-O-(3",6"-di-O-E-p-coumaroyl)-β-glycoside and extracts of Calotropis procera, Ephedra foeminea, Artemisia herba-alba, Hylocereus undatus and Marrubium vulgare showed potential inhibitory activity, where the butanol extract of Calotropis procera was found to have 85.3% inhibition of dipeptidyl peptidase-IV at 0.2 mg/100 µL concentration.
