The lipophilicity of a set of 5-HT(2A) ligands was determined using immobilized-artificial-membrane chromatography, a method that generates values well correlated with octanol-water partition coefficients. For agonists, a highly significant linear correlation was observed between binding affinity and lipophilicity. For ligands
