BICYCLIC CARBOXAMIDES AS 5-HT1A ANTAGONISTS

摘要

Bicyclic carboxamides of formula (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 -CR<2> = CR<2>- or -(CR<2>)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; R<1> is an aryl or aryl(lower)alkyl radical; and each R<2> is independently hydrogen or lower alkyl.
