Molecular Determinants for Ligand Binding at Serotonin 5-HT_2A and 5-HT_2C GPCRs: Experimental Affinity Results Analyzed by Molecular Modeling and Ligand Docking Studies.

ABSTRACT: Ligands that activate the serotonin 5-HT_2C G protein-coupled receptor (GPCR) may be therapeutic for psychoses, addiction, and other neuropsychiatric disorders. Ligands that are antagonists at the closely related 5-HT_2A GPCR also may treat neuropsychiatric disorders; in contrast, 5-HT_2A activation may cause hallucinations. 5-HT_2C-specific agonist drug design is challenging because 5-HT₂ GPCRs share 80% transmembrane (TM) homology, same second messenger signaling, and no crystal structures are reported. To help delineate molecular determinants underlying differential binding and activation of 5-HT₂ GPCRs, 5-HT_2A, and 5-HT_2C homology models were built from the β₂-adrenergic GPCR crystal s
