摘要

A series of N1-azinylsulfonyl-3-(1,2,3,6,tetrahyrdopyridin-4-yl)-1H-indole derivatives was designed to obtain highly potent 5-HT6 receptor ligands. The study allowed for the identification of >25 (4-{[5-methoxy-3-(1,2,3,6-tetrahydropyridin-4-yl)-1H-indol-1-yl]sulfonyl}isoquinoline), a potent and selective 5-HT6 receptor antagonist. The selected compound, was evaluated in vivo in a novel object recognition (NOR) and forced swim (FST) tests in rats, demonstrating distinct pro-cognitive and antidepressant-like properties (MED = 1 mg/kg and 0.1 mg/kg, i.p., respectively). Compound SB-742457, used as comparator, reversed memory deficits in NOR task in similar doses, while in FST it was active in 10–30-fold higher dose (3 mg/kg). In contrast to SB-742457, which was active in Vogel test (MED = 3 mg/kg), compound >25 displayed no anxiolytic activity.
