In the present paper, we report the synthesis and the binding profile on 5-HT1A, alpha(1), and D-2 receptors of a new series of imide-arylpiperazines 3. The study oft he length of the alkyl chain and the imide substructure allows us to suggest some important differences between the no-pharmacophoric sites of both 5-HT1A and alpha(1)-adrenergic receptors, which could be of great importance in order to design new selective ligands.
