Abstract : A series of 5-HT(6) ligands derived from (R)-1-(amino)methyl-6-(phenyl)sulfonyltetralin was prepared that yielded several non-basic analogs having sub-nanomolar affinity. Ligand structure-activity relationships, receptor point mutation studies, and molecular modeling of these novel ligands all combined to reveal a new alternative binding mode to 5-HT(6) for antagonism.
