PF-04620110 is an orally active, selective and potent DGAT1 (Acyl-CoA:diacylglycerol acyltransferase 1) inhibitor that inhibits triacylglycerol synthesis in cells and in rodents. PF-04620110 inhibits DGAT-1 with an IC50 of 19 nM and shows high selectivity versus a broad panel of off-target pharmacologic end points. In vivo DGAT-1 inhibition has been demonstrated through reduction of plasma triglyceride levels in rodents at doses of ≥0.1 mg/kg following a lipid challenge. On the basis of this pharmacologic and pharmacokinetic profile, PF-04620110 has been advanced to human clinical studies. PF-4620110 had been in phase I clinical trials by Pfizer for the treatment of type 2 diabetes. But this research was discontinued in 2011.
