Patent ID: 7153859

Claim:
A condensed polycyclic compound of the formula [I]: wherein, R 1 and R 2 are the same or different and each is a group selected from a hydroxy group or a lower alkoxy group; ring A 0 is a group of the formula: ring A is a substituted or unsubstituted benzene ring or a substituted or unsubstituted 5- to 6-membered monocyclic aromatic heterocyclic ring containing 1 to 3 nitrogen atoms, wherein the substitutents are selected from the group consisting of a lower alkoxy group, a hydroxyl group and a halogen atom; R 3 is: (1) a hydrogen atom, a group of the formula: —(CH 2 ) m —R 31 or a group of the formula: —CO—R 32 , when ring A is a substituted benzene ring or a substituted or unsubstituted 5- to 6-membered monocyclic aromatic heterocyclic group containing 1 to 3 nitrogen atoms; or (2) a group of the formula: —(CH 2 ) m —R 31 or a group of the formula: —CO—R 32 , when ring A is an unsubstituted benzene ring; R 31 is a hydrogen atom, an aryl group, a hydroxy group, an amino group, a carboxyl group, a lower alkoxycarbonyl group or a lower alkylthio group; R 32 is an aryl group, a lower alkyl group, a hydroxy-lower alkyl group or an amino-lower alkyl group; m is an integer of 1 to 6; and Q is a single bond linked to ring A; or a pharmaceutically acceptable salt thereof.
