A condensed indan derivative represented by the formula (1)n wherein the ring A is an optionally substituted benzene ring or a benzene ring which has lower alkylenedioxy group(s), the ring B is an optionally substituted benzene ring or a benzene ring which has lower alkylene dioxy group(s), and R is a group -NR 1 R 2 , an optionally substituted nitrogen-containing heterocyclic group, a group -OR 3 or a group -SR 4 (wherein R 1 and R 2 are the same or different and each represent a hydrogen atom, a phenyl group, an optionally substituted nitrogen-containing heterocyclic group, or a lower alkyl group which may be substituted by optionally substituted amino group(s), lower alkoxy group(s), phenyl group(s), nitrogen-containing heterocyclic group(s) or hydroxyl group(s), and R 3 and R 4 each represent a lower alkyl group which may be substituted by substituted amino group(s)), provided that at least one of the rings A and B is a substituted benzene ring and R is not -NHCH 3 , and salts thereof, and medical use of said derivative and salts. |
