Patent ID: 8349840

Claim:
A pharmaceutical composition comprising a heterocyclic compound of the formula (1) or a salt thereof as an active ingredient and a pharmaceutically acceptable carrier: wherein ring Q represented by represents wherein represents —NH—CH 2 —, —N═CH—, —CH 2 —NH— or —CH═N—; and the carbon-carbon bond between the 3-position and 4-position of the heterocyclic skeleton containing Z and Y represents a single bond or a double bond; the ring Q may have at least one substituent selected from the group consisting of a lower alkyl group, a lower alkenyl group, a lower alkynyl group, a hydroxy group, a lower alkoxy group, a halogenated lower alkyl group, an aryl group, an aryl lower alkyl group, an aryl lower alkoxy group, an arylcarbonyl group, a lower alkenyloxy group, a lower alkanoyl group, a lower alkanoyloxy group, a cycloalkyl group, a cycloalkyl lower alkyl group, a halogen atom, a carbamoyl group which may have a lower alkyl group, a carboxy group, a lower alkoxycarbonyl group, an amino group which may have a lower alkanoyl group, a nitro group, a hydroxy lower alkyl group, an amino lower alkyl group which may have a lower alkyl group, a thienyl group, a saturated 3- to 8-membered heteromonocyclic group containing 1 to 2 nitrogen atoms-substituted lower alkyl group and an oxo group; R 2 represents a hydrogen atom or a lower alkyl group; and A represents —O -A 1 - (wherein A 1 represents an alkylene group which may be substituted with a hydroxy group (wherein the one oxygen atom may replace a carbon of the alkylene chain) or a lower alkenylene group) or a lower alkylene group; provided that when A represents a lower alkylene group, the ring Q represents a bicyclic group selected from the group consisting of: wherein the carbon-carbon-bond represents a single bond or a double bond.
