A series of 5-HT6 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-HT6 for antagonism.
