Title: (EN) Quinoline derivatives, their production and use as ACAT inhibitors
Abstract: front page image
(EN)

A quinoline derivative of the formula (I): ##STR1## wherein each phenyl ring of A and B can have one or more substituents; X is ##STR2## (R.sup.1 is a hydrogen atom, a lower alkyl group or a lower alkoxy group) or ##STR3## (R.sup.2 is a hydrogen atom or a lower alkyl group); Y is --(CH.sub.2).sub.m --(m is 0, 1 or 2) or --CH.dbd.CH--, Z is a group of the formula: ##STR4## wherein each phenyl ring of C and D can have one or more substituents, R.sup.3 and R.sup.4 are each a hydrogen or halogen atom, or a lower alkyl, lower alkoxy, lower acyloxy, lower alkoxycarbonyloxy, N,N-di-lower alkylcarbamoyloxy, optionally esterified carboxy or hydroxyl group, R.sup.5 is a halogen atom, or a lower alkyl, lower alkoxy, lower acyloxy, lower alkoxycarbonyloxy, N,N-di-lower alkylcarbamoyloxy, optionally esterified carboxy or hydroxyl group, R.sup.6 and R.sup.7 are each a hydrogen atom or a lower alkyl group, and n, o and p are each 1 or 2; l is 0 or 1; or its salt, which is useful as a drug for atherosclerosis.
