Novel acyl coenzyme A (CoA): Diacylglycerol acyltransferase-1 inhibitors: Synthesis and biological activities of diacylethylenediamine derivatives

A series of diacylethylenediamine derivatives were synthesized and evaluated for their inhibitory activity against DGAT-1 and pharmacokinetic profile to discover new small molecule DGAT-1 inhibitors. Among the compounds, N-[2-({[1-phenyl-3-(trifluoromethyl)-1H-pyrazol-4-yl]carbonyl}amino)ethyl]-6-(2,2,2-trifluoroethoxy)pyridine-3-carboxamide 3x showed potent inhibitory activity and excellent PK profile. Oral administration of 3x to mice with dietary-induced obesity resulted in reduced body weight gain and white adipose tissue weight.
