Bicyclic carboxamides as 5-htÕ1a? antagonists

摘要

Bicyclic carboxamides of formula I (I) and the pharmaceutically acceptable acid addition salts are 5-HT1A binding agents, particularly 5-HT1A antagonists and may be used, for example, as anxiolytics. In the formula X represents -CR2=CR2- or -(CR2)q-; m represents 0,1 or 2; n represents 0,1 or 2; p represents 0,1,2 or 3 and q represents 0,1,2 or 3; A is an alkylene chain of 1 or 2 carbon atoms optionally substituted by one or more lower alkyl groups, R is a mono or bicyclic aryl or heteroaryl radical, R1 is an aryl or aryl(lower)alkyl radical and each R2 is independently hydrogen or lower alkyl.
