Aromatic interactions impact ligand binding and function at serotonin 5-HT_2C G protein-coupled receptors: Receptor homology modeling, ligand docking, and molecular dynamics results validated by experimental studies.

ABSTRACT: The serotonin (5-hydroxytryptamine, 5-HT) 5-HT₂ G protein-coupled receptor (GPCR) family consists of types 2A, 2B, and 2C that share ~75% transmembrane (TM) sequence identity. Agonists for 5-HT_2C receptors are under development for psychoses, whereas, at 5-HT_2A receptors, antipsychotic effects are associated with antagonists-in fact, 5-HT_2A agonists can cause hallucinations and 5-HT_2B agonists cause cardiotoxicity. It is known that 5-HT_2A TM6 residues W6.48, F6.51, and F6.52 impact ligand binding and function, however, ligand interactions with these residues at the 5-HT_2C receptor has not been reported. To predict and validate molecular determinants for 5-HT_2C-specific activation, results from receptor
