Description
TAK-875 is a novel, orally available, selective GPR40 agonist. TAK-875 exhibits potent agonist activity and high binding affinity to the human GPR40 receptor with Ki of 38 nM. TAK-875 enhanced glucose-induced insulin secretion in a glucose-dependent manner in both human and rat islets. In rat insulinoma INS-1 833/15 cells, TAK-875 increased intracellular inositol monophosphate and calcium concentration, consistent with activation of the Gqα signaling pathway. In addition, TAK-875 (10 mg/kg, p.o.) significantly augmented plasma insulin levels and reduced fasting hyperglycemia in male Zucker diabetic fatty rats, whereas in fasted normal Sprague-Dawley rats, TAK-875 neither enhanced insulin secretion nor caused hypoglycemia even at 30 mg/kg. TAK-875 improves both postprandial and fasting hyperglycemia with a low risk of hypoglycemia and no evidence of β cell toxicity. TAK-875 significantly improved glycaemic control in patients with type 2 diabetes with minimum risk of hypoglycaemia
