demonstrated moderate to high affinity for 5-HT1A and alpha1 receptorbinding sites but had no affinity for D2 receptors. The study of the length of the alkyl chain and the imide substructure has allowed us to suggest some differences between the 5-HT1A and the alpha1-adrenergic receptors: (i) for III and IV, affinity for the 5-HT1A receptor as a function of the length of the methylene linker decreases
