Description: AM-1638, also known as AMG-1638, is a potent and orally Bioavailable GPR40/FFA1 Full Agonist. Activation of FFA1 (GPR40), a member of G protein-coupling receptor family A, is mediated by medium- and long-chain fatty acids and leads to amplification of glucose-stimulated insulin secretion, suggesting a potential role for free fatty acid 1 (FFA1) as a target for type 2 diabetes.
