The mechanism of action about this chemical: It is an inhibitor of DPP-4 which degrades the incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). Both GLP-1 and GIP increase insulin biosynthesis and secretion from pancreatic beta cells in the presence of normal and elevated blood glucose levels. Thus, this chemical stimulates the release of insulin in a glucose-dependent manner and decreases the levels of glucagon in the circulation.
