Abstract

A novel series of 3-arylsulfonylamino-5,6-dihydro-6-substituted-1H-pyrazolo[3,4-c]pyridine-7-ones was designed and synthesized as 5-HT6 ligands. Among the derivatives synthesized, the lead compound, 12b, having piperidine functionality at the 6-position and (1-naphthyl)sulfonamino at the 3-position of the core structure showed the most potent 5-HT6 inhibitory activity in vitro, good stability without CYP liability, and good neuropathic pain alleviation activity in a rat animal model.
