Structure-activity relationship of N-[2-(dimethylamino)-6-[3-(5-methyl-4-phenyl-1H-imidazol-1-yl)propoxy]phenyl]-N'-pentylurea and analogs. Novel potent inhibitors of acyl-CoA:cholesterol O-acyltransferase with antiatherosclerotic activity
urea (4), a novel, potent, and systemically bioavailable inhibitor of ACAT (acylCoA:cholesterolO-acyltransferase). The structure-activity relationships (SARs) of this lead compound 4 were investigated by systematic modification of four regions in the molecule. The compounds prepared in this study were tested for in vitro inhibitory activity toward both aortic and intestinal ACATs, and selected compounds
