A series of new arylpiperazine derivatives 2, which are devoid of the terminal amide fragment present in related 5-HT1A ligands, was prepared and evaluated for affinity at 5-HT1A and alpha 1 receptors. All the compounds 2 demonstrated high affinity for the 5-HT1A receptor and moderate affinity for alpha 1 receptor binding sites. Structure-activity relationship (SAR) studies suggest that there is influence
