A novel series of rigidized indolyl pyrrolidine derivatives have been designed by constraining the tryptamine nitrogen through a and b carbons. All the synthesized derivatives have shown moderate affinities at 5-HT6R when tested in in vitro binding assay.

Several series of conformationally constrained N1- arylsulfonyltryptamine derivatives were prepared and tested for 5-HT6 receptor binding affinity and ability to modulate cAMP production in a cyclase assay. The 3-piperidin-3-yl-, 3-(1-methylpyrrolidin-2-ylmethyl)-, and 3-pyrrolidin-3-yl-1H-indole arrays (8-13) appear to be able to adopt a conformation that allows high affinity 5-HT6 receptor binding, while the β-carboline array 14 binds with a significantly weaker (10- to 100-fold) affinity. N1-Benzenesulfonyl-3-piperidin-3-yl-1H-indole 9a is a high affinity full agonist with EC50 = 24 nM. Several of the N1-arylsulfonyl-3-(1-methylpyrrolidin-2-ylmethyl)-1H-indole derivatives behave as very potent antagonists ((S)-11r, (S)-11t; IC50 = 0.8, 1.0 nM).
