Novel 3-(arylsulfonyl)-1-(azacyclyl)-1H-indoles 6 were synthesized as potential 5-HT6 receptor ligands, based on constraining a basic side chain as either a piperidine or a pyrrolidine. Many of these compounds had good 5-HT6 binding affinity with K-i values <10 nM. Depending on substitution, both agonists (e. g., 6o: EC50 = 60 nM, E-max = 70%) and antagonists (6y: IC50 = 17 nM, I-max = 86%) were identified in a 5-HT6 adenylyl cyclase assay.
