GW4064

GW4064 is a FXR agonist. There is no activity of GW4064 at other nuclear receptors at concentrations up to 1 μM. Treatment of differentiated 3T3-L1 adipocytes with the FXR-specific synthetic agonist GW4064 enhanced insulin signaling and insulin-stimulated glucose uptake. Finally, treatment with GW4064 improved insulin resistance in genetically obese ob/ob mice in vivo. Pharmacokinetic analysis in rats shows that GW 4064 possesses an oral bioavailability of 10% with a t1/2 = 3.5 h. Fisher rats are dosed with GW 4064 by oral gavage. After 7 days, a dose-dependent lowering of serum triglycerides is observed in the rats receiving GW 4064, with an ED50 = 20 mg/kg.
