摘要

A condensed-indan derivative of the general formula (I) and pharmaceutically acceptable salts thereof:;Wherein ring A is an optionally substituted benzene ring or naphthalene ring or a benzene ring having a lower alkylenedioxy group and ring B is an optionally substituted benzene ring or a benzene ring having a lower alkylenedioxy group, N = CR-or-CR = N-, and R is-NR_OneR₂Group, an optionally substituted nitrogen-containing heterocyclic group, or-OR₃Group, R_OneAnd R₂Are the same or different and each is a hydrogen atom; Phenyl group; An optionally substituted nitrogen-containing heterocyclic group; Or an optionally substituted amino group, a lower alkoxy group, a phenyl group, a nitrogen-containing heterocyclic group, an amine oxide group substituted by a lower alkyl group, or a hydroxyl group (s) Lower alkyl group, R₃Is a lower alkyl group optionally substituted by a substituted amino group, provided that when R is an optionally substituted nitrogen-containing heterocyclic group, ring A and ring B are not a benzene ring without substituent.
