The role of lipophilicity in determining binding affinity and functional activity for 5-HT2A receptor ligands
摘要:
The lipophilicity of a set of 5-HT2A 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 exhibiting partial agonist or antagonist properties, the lipophilicity was consistently higher than would be expected for an agonist of comparable affinity. The results suggest a possible method for distinguishing agonists from antagonists in high-throughput screening when a direct assay for functional activity is either unavailable or impractical.
