Patent ID: 7960402

Claim:
A compound of the formula (I): wherein, X, Y, Z and W each independently represent a methine group optionally having a substituent(s) selected from the group α, A represents —O— or N(R 5 )—, B represents —C(O)—, D represents a bond, Q represents a methine group or a nitrogen atom, R 5 represents a hydrogen atom, a lower alkyl group, an aralkyl group or an aryl group, R represents a group of the following formula (II) which may have a substituent selected from the group consisting of a lower alkyl group (said lower alkyl group may be substituted with a halogen atom, an oxo group or an alkoxy group), a cycloalkyl group, a hydroxy group, an alkoxy group (said alkoxy group may be substituted with a halogen atom) and a halogen atom; wherein, R 6 represents a hydrogen atom or a lower alkyl group, R 7 and R 8 each independently represent a lower alkyl group, a cycloalkyl group, an aralkyl group, a heteroaryl alkyl group or R 7 and R 8 together with the nitrogen atom to which they bond form a four- to eight-membered nitrogen-containing aliphatic heterocyclic group; or when R is the above formula (II-3), C a and R 7 together with the nitrogen atom to which bond form a four- to eight-membered nitrogen-containing aliphatic heterocyclic group; and the formula wherein (II-2), (II-4) and (II-5) represent a four- to eight-membered nitrogen-containing aliphatic heterocyclic group), m1 and m2 each independently indicate 0 or 1, r indicates an integer of 0 to 2, t indicates 1 or 2; u indicates 0 or 1 (with a proviso that t+u is 2); the group α is selected from: a halogen atom, a hydroxyl group, a lower alkyl group (said group may be substituted with a halogen atom, a hydroxyl group or an alkoxy group), a cycloalkyl group (said group may be substituted with a halogen atom, a hydroxyl group or an alkoxy group), an alkoxy group (said group may be substituted with a halogen atom or a hydroxyl group), an amino group, a cyano group, a mono- or di-(lower alkyl)amino group, a formyl group, an alkanoyl group, a mono- or di-lower alkylcarbamoyl group, an arylcarbamoyl group, a heteroarylcarbamoyl group, an arylalkylcarbamoyl group, a heteroarylalkylcarbamoyl group, a lower alkylsulfonyl group, a lower alkylthio group, an aryloxycarbonylamino group, an arylalkyloxycarbonylamino group, an alkoxycarbonylamino group, an alkanoylamino group, an arylcarbonylamino group, an arylalkylcarbonyl group, a lower alkylsulfonylamino group, an arylsulfonylamino group, a lower alkylsulfamoyl group, an arylsulfamoyl group, an aryl group, an aryloxy group, a heteroaryl group and an aralkyl group; or a pharmaceutically acceptable salt thereof.
