The present invention offers novel cyclic diamine compounds and a pharmaceutical composition containing the same. The present invention relates to a compound represented by the formula (I) or salt(s) or solvate(s) thereof. (In the formula, is an optionally substituted divalent residue of benzene, pyridine, cyclohexane or naphthalene or is a vinylene group where Ar is an optionally substituted aryl group; X is -NH-, oxygen atom or sulfur atom; Y is -NR1-, oxygen atom, sulfur atom, sulfoxide or sulfone; Z is a single bond or -NR2-; R1 is hydrogen atom, optionally substituted lower alkyl group, optionally substituted aryl group or optionally substituted silyl lower alkyl group; R2 is hydrogen atom, optionally substituted lower alkyl group, optionally substituted aryl group or optionally substituted silyl lower alkyl group; l is an integer of from 0 to 15; m is an integer of 2 or 3; and n is an integer of from 0 to 3). The compound of the present invention is useful as a pharmaceutical composition, particularly as an inhibitor of acyl coenzyme A cholesterol acyltransferase (ACAT). |
