• 产品描述： AMG 837 calcium hydrate is a potent, orally bioavailable and partial agonist of GPR40/FFA1. AMG 837 calcium hydrate inhibits specific [3H]AMG 837 binding at the human FFA1 receptor with a pIC50 of 8.13. AMG 837 calcium hydrate could enhance insulin secretion and lower glucose levels in rodents

• 靶点： pIC50: 8.13 (FFA1);GPR

• 体外研究：
  AMG 837 (1 nM-10 μM) stimulates insulin secretion in a glucose-dependent manner with an EC50 of 142±20 nM on islets isolated from mice. AMG 837 stimulates Ca2+ flux with the EC50s of 13.5, 22.6 and 31.7 nM for human, mouse and rat receptors in CHO cells, respectively

• 体内研究：
  AMG 837 (0.03-0.3 mg/kg; p.o. once daily for 21 days) reduces glucose levels and increases insulin levels following glucose challenge in vivo[1].AMG 837 (0.03-0.3 mg/kg; a single p.o.) improves glucose tolerance and enhances insulin secretion in Sprague-Dawley rats. AMG 837 (0.5 mg/kg; p.o.) displays excellent oral bioavailability (F = 84%) and a total plasma Cmax of 1.4 µM. Animal Model: 8-week old Zucker Fatty Rats Dosage: 0.03, 0.1, 0.3 mg/kg Administration: Oral gavage once daily for 21 days Result: Decreased glucose AUC values during the glucose tolerance test (GTT) to 7%, 15%, and 25% at 0.03, 0.1 and 0.3 mg/kg, respectively.Increased insulin levels in the mid- and high-dose groups.Not affected body weights during the 21-day treatment. Animal Model: 8-week old Sprague-Dawley rats Dosage: 0.03, 0.1, 0.3 mg/kg Administration: A single p.o. administration Result: Reduced the post-prandial glucose with the half-maximal dose of 0.05 mg/kg.
