Patent ID: 7550464

Claim:
A method for treatment of a disease selected from the group consisting of asthma, chronic obstructive pulmonary disease, atopic dermatitis, allergic rhinitis, psoriasis, rheumatoid arthritis, septic shock, ulcerative colitis, and Crohn's disease, which comprises administering an effective amount of 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 group 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 or an effective amount of a PDE4 inhibitor comprising as an active ingredient the said compound, to a patient in need thereof.
