K-757
K-757 is an orally active, gut-targeted GPR40 agonist with EC50 values of 2.1 nM, 5.6 nM, 4.2 nM and 166 nM in humans, mice, rats and dogs, respectively. K-757 activates nutrient receptors co-expressed on pancreatic β cells and intestinal enteroendocrine cells. K-757 mediates and induces the secretion of satiety hormones GLP-1 and PYY in multiple in vitro and in vivo models. When used in combination with GPR119 agonist K-833, K-757 acts as a potentiator to elevate circulating levels of satiety hormones. K-757 can be used in the research of type 2 diabetes, weight loss and other related metabolic disorders.

K-757 (1-30 μM; 2.5 h) induces concentration-dependent GLP-1 secretion in wild-type mouse colonic crypt cultures via GPR40 activation, with no activity observed in GPR40 knockout cultures[2].
K-757 (0.01-30 μM; 2.5 h) induces concentration-dependent GLP-1 and PYY secretion in human ileal crypt cultures, with maximal responses at 10 and 30 μM[2].

K-757 (0.3-30 mg/kg; p.o.; single dose, co-administered with K-833 30 mg/kg) in combination with K-833 induces enhanced GLP-1 secretion in fasted C57BL/6J mice, with maximal efficacy achieved at a 3 mg/kg single dose of K-757[2].
K-757 (10 mg/kg; p.o.; single dose) induces sustained GLP-1 secretion in fasted male Beagle dogs for at least 5 hours postdose[2].

Animal Model:C57BL/6J (male, 10−12 weeks old)[2]
-
Dosage:3 mg/kg; 10 mg/kg; 30 mg/kg; 60 mg/kg
-
Administration:p.o.; single dose
-
Result:Elicited dose-dependent increases in plasma GLP-1 levels 1 hour postdose.
