Claim:
A compound represented by the formula (I): wherein ring A′ and ring B′ are optionally further substituted benzene rings; X is —CONR 4 —, —SO 2 NR 4 —, —CH 2 NR 4 —, —NR 4 CO—, —NR 4 SO 2 —, —NR 4 —CO—NH—, —O—, —S—, —SO—, —SO 2 —, —CO—, —CO 2 —, —CH═CH— or a bond (R 4 is a hydrogen atom, an optionally substituted hydrocarbon group lo or an optionally substituted heterocyclic group); Y is a saturated divalent group selected from (1) —(CH 2 ) f1 —(f1 is an integer of 1 to 12), (2) —(CH 2 ) g1 —Y 1 —(CH 2 ) g2 —(g1 and g2 are the same or different and an integer of 0 to 11, provided that the sum of g1 and g2 is 0 to 11, and Y 1 is NH, O, S, SO or SO 2 ) and (3)-(CH 2 ) h1 —Y 1 —(CH 2 ) h2 —Y 2 —(CH 2 ) h3 —(h1, h2 and h3 are the same or different and an integer of 0 to 10, provided that the sum of h1, h2 and h3 is 0 to 10, and Y 1 and Y 2 are independently NH, O, S, SO or SO 2 , provided that when h2 is 0, at least one of Y 1 and Y 2 is NH) or a divalent group thereof wherein some bonds of the divalent group are converted to unsaturated bonds, each of divalent group may have substituent(s); Z is —CONR 6 —, —CSNR 6 —, —CO— or —SO 2 — (R 6 is a hydrogen atom, an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group); R 1 is an optionally substituted amino group or an optionally substituted heterocyclic group; R 2 is a hydrogen atom, an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group; R 3 is an optionally substituted piperidinyl group; and R 5 is methyl; or a salt thereof.
