MK-2305
MK-2305 is an orally active GPR40 partial agonist with an EC50 of 6 nM in rats. MK-2305 mediates glucose-stimulated insulin secretion and inhibits endogenous glucose production by reducing gluconeogenesis from tricarboxylic acid (TCA) cycle substrates. MK-2305 increases plasma insulin levels under hyperglycemic and glucose-stimulated conditions, reduces fasting blood glucose, and improves glucose homeostasis. MK-2305 can be used in studies related to type 2 diabetes.

GPR40 6 nM (EC50) |
MK-2305 (60 min) potently and selectively activates rat GPR40 in CHO cells with an EC50 of 6 nM and 166% partial activation, while showing minimal activity against other metabolic receptors[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
MK-2305 (10-30 mg/kg/day; p.o.; daily via diet; 20 days) reduces both fed and fasting blood glucose, lowers HbA1c, and enhances glucose-stimulated insulin secretion in male GK rats, with a 30 mg/kg/day dose producing a 30% reduction in fasting glucose on day 14[1].
MK-2305 (10 mg/kg; p.o.; single dose; 10 mg/kg/day; p.o.; daily) reduces endogenous glucose production in male GK rats, primarily through suppression of gluconeogenesis, with acute treatment lowering total EGP by 36.7%[1].
MK-2305 (10 mg/kg; p.o.; single dose) does not enhance glucose uptake in skeletal muscle or liver of male GK rats, instead reducing hepatic glucose disposal into glycogen and glycolytic products[1].
