Structure-activity relationship of a series of phenylureas linked to 4-phenylimidazole. Novel potent inhibitors of acyl-CoA:cholesterol O-acyltransferase with antiatherosclerotic activity. 2
(acyl-CoA:cholesterolO-acyltransferase) inhibitors with more potent antiatherosclerotic effect than N-[2-(dimethylamino)-6-[3-(5-methyl-4-phenyl-1H-imidazol-1-yl)propoxy] phenyl]-N'-pentylurea (3), a series of phenylureas linked to 4-phenylimidazole were synthesized and evaluated for in vitro inhibitory activity toward both aortic and intestinal ACATs, and for in vivo hypocholesterolemicactivity.
