Patent ID: 8563565

Claim:
A compound represented by the formula (I) or a pharmacologically acceptable salt thereof: wherein R 1 is a hydrogen atom; R 2 is an aromatic ring group selected from the group consisting of a phenyl group, a pyridinyl group, and a pyrimidinyl group, where the two atoms on the aromatic ring which are adjacent to the carbon atom attached to the pyrazolo[4,3-c]quinoline ring each independently has a substituent selected from Group A1, and the other atoms on the aromatic ring independently optionally have a substituent selected from Group B1; R 3 is a hydrogen atom, or a fluorine atom; R 4 is a hydrogen atom; R 5 is an oxepanyl group, a dioxepanyl group, a tetrahydropyranyl group, or a tetrahydrofuranyl group optionally substituted with a methoxy group; R 6 is a hydrogen atom; Group A1 consists of a halogen atom, a C1-6 alkyl group optionally substituted with 1 to 3 halogen atoms, and a C1-6 alkoxy group; and Group B1 consists of a halogen atom, a cyano group, a C1-6 alkyl group optionally substituted with 1 to 3 halogen atoms, a C1-6 alkoxy-C1-6 alkyl group, a C1-6 alkoxy group optionally substituted with 1 to 3 halogen atoms, and a tetrahydropyranyl group, with the proviso that when R 2 is a 3-pyridinyl group, the substituent at the 4-position is a halogen atom, or a C1-6 alkyl group optionally substituted with 1 to 3 halogen atoms.
