The 5‐HT1a and 5‐HT2 receptoraffinity of a set of 44 N‐alkylated 1‐arylpiperazines and their analogs has been analyzed: the n‐hexyl derivatives were the most potent and the most selective 5‐HT1a ligands of all the investigated N‐alkyl homologues. The alkylchain may stablize the 5‐HT1a receptor‐ligand complex by hydrophobic forces. A set of the alkyl substituent contributions (Cht1a) for prediction
