AS-1269574 is a potent and selective agonist of the G protein-coupled receptor 119 (GPR119). It is primarily utilized in biomedical research to study the physiological roles of GPR119, particularly in regulating glucose homeostasis and insulin secretion. This compound enhances glucose-dependent insulin release from pancreatic β-cells without significantly increasing the risk of hypoglycemia, making it a valuable tool for investigating potential treatments for type 2 diabetes mellitus and related metabolic disorders. AS-1269574 is employed in preclinical studies to explore GPR119-mediated signaling pathways and serves as a lead compound in drug discovery efforts aimed at developing novel antidiabetic agents. It is not approved for clinical use and remains a research reagent.
