Claim:
A compound of the formula [I]: wherein G 1 is an alkyl which is substituted by a halogen atom or an alkoxy, or a group of the formula: wherein ring B is benzene ring, naphthalene ring, a monocyclic or bicyclic aromatic heterocycle or a cycloalkane, and the benzene ring, the naphthalene ring, the monocyclic or bicyclic aromatic heterocycle and the cycloalkane may be substituted by 1 to 3 substituent(s), which is(are) the same or different, and selected from the group consisting of a halogen atom, nitro, an optionally substituted alkyl, an optionally substituted alkoxy, an optionally substituted amino, an optionally substituted carbamoyl, hydroxy and cyano, W is a single bond, or a c 1 -c 4 alkylene which may be substituted by 1 or 2 alkyl(s), Q 1 and Q 2 are the same or different, and each is a hydrogen atom, a halogen atom or an alkyl, n is 0, 1, 2, 3 or 4, R 1 is a hydrogen atom, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted phenyl or an optionally substituted heterocyclic group, Z 1 is CH, Z 2 , Z 3 and Z 4 may be the same or different, and each of Z 2 , Z 3 and Z 4 is CH or N, provided that all of Z 2 , Z 3 and Z 4 should not be N at the same time, G 2 is a hydrogen atom, —NR 3 R 4 , —OR 5 , —SR 5 —COR 6 , —CHR 7 R 8 , or a heterocyclic group, wherein each of R 3 to R 8 is independently a hydrogen atom, an optionally substituted alkyl, an alkenyl, an alkynyl, hydroxy, an alkoxy, an optionally substituted amino, an optionally substituted alkanoyl, an optionally substituted carbamoyl, an alkoxyoxalyl, an alkylsulfonyl, an optionally substituted cycloalkyl, an optionally substituted phenyl, an optionally substituted heterocyclic group, a carbonyl substituted by an optionally substituted cycloalkyl, a carbonyl substituted by an optionally substituted phenyl or a carbonyl substituted by an optionally substituted heterocyclic group; or a pharmaceutically acceptable salt thereof.
