New 2-methoxyphenylpiperazine derivatives are described with the following general formula:
where A is a carbonyl group, an alkylaminocarbonyl or alkylaminomethylene group, and B is a substituted aryl, heteroaryl substituted or otherwise, arylalkyl, heteroarylalkyl or cycloalkyl group, and their pharmaceutically acceptable addition salts. These compounds have a pharmacologic activity at the level of serotonin 5-HT1A receptors.
New (2-Methoxyphenyl)piperazine Derivatives as 5-HT1A Receptor Ligands with Reduced .alpha.1-Adrenergic Activity. Synthesis and Structure-Affinity Relationships
New 2-(methoxyphenyl)piperazine derivatives 1 and 2 containing a terminal heteroaryl or cycloalkyl amide fragment were prepared and their 5-HT1A affinities evaluated by radioligand binding assays. The influence of the alkyl chain length or the amide group on affinity was evaluated. A four-carbon chain appears to be optimal when the amide fragment is a heteroaryl group. Derivatives with a cycloalkyl
