Further studies in quest of 5-HT(6) serotonin receptor ligands led to the design and synthesis of a few selected examples of N-(inden-5-yl)sulfonamides with a ring-constrained aminoethyl side chain at the indene 3-position, some of which exhibited a high binding affinity, such as the pyrrolidine analogue 28 (K(i)=3nM). Moreover, the structurally abbreviated N-(inden-5-yl)sulfonamides showed K(i) values > or = 43 nM, which indicates that neither the N,N-aminoethyl nor the conformationally restricted aminoethyl side arm at the indene 3-position are required for binding. Selected compounds were then tested in a functional cAMP stimulation assay and found to act as 5-HT(6) antagonists, although with moderate potency at the micromolar level.
