A-922500

A-922500 is a potent orally active inhibitor of DGAT-1 activity, inhibiting both human and mouse forms of the enzymes with IC50 values of 7 and 24 nM, respectively. DGAT-1 deficient mice demonstrate a phenotype that is protective against the development of diet-induced obesity (DIO) or insulin resistance, implicating the actions of this enzyme in the development of such metabolic disorders. A-922500 conferred significant weight loss within seven days without affecting food intake and significantly reduced plasma and liver triglycerides with chronic dosing when administered at 3 mg/kg to DIO mice. DGAT-1 inhibitor A-922500 (0.03, 0.3 and 3 mg/kg, p.o.), dose-dependently attenuated the maximal postprandial rise in serum triglyceride concentrations. A-922500 is devoid of activity at DGAT-2, ACAT1 or ACAT2.
