Overview

N-acetyl glucose-dependent insulinotropic polypeptide (Ac-GIP) is a synthetic, N-terminally modified analog of the native incretin hormone glucose-dependent insulinotropic polypeptide (GIP). By acetylating the N-terminal amino acid, the peptide becomes highly resistant to degradation by the enzyme dipeptidyl peptidase IV (DPP-IV), which normally inactivates native GIP within minutes. This modification significantly enhances its plasma stability, potency, and duration of action. Ac-GIP acts as a potent agonist at the gastric inhibitory polypeptide receptor (GIPR), stimulating insulin secretion in a glucose-dependent manner and improving glucose tolerance. It has been primarily investigated in preclinical research settings, notably by researchers at the University of Ulster, for the potential treatment of type 2 diabetes mellitus and obesity-related metabolic disorders, as well as for potential applications in neuroendocrine tumor imaging.
