Serotonin 5-HT6 receptor antagonists for the treatment of cognitive deficiency in Alzheimer's disease.
Alzheimer's disease (AD) is one of the most frequent causes of death and disability worldwide and has a significant clinical and socioeconomic impact. In the search for novel therapeutic strategies, serotonin 5-HT6 receptor (5-HT6R) has been proposed as a promising drug target for cognition enhancement in AD. This manuscript reviews the compelling evidence for the implication of this receptor in learning and memory processes. We have summarized the current status of the medicinal chemistry of 5-HT6R antagonists and the encouraging preclinical findings that demonstrate their significant procognitive behavioral effects in a number of learning paradigms, probably acting through modulation of multiple neurotransmitter systems and signaling pathways. The results of the ongoing clinical trials are eagerly awaited to shed some light on the validation of 5-HT6R antagonists as a new drug class for the treatment of symptomatic cognitive impairment in AD, either as stand-alone therapy or in combination with established agents.

Rigidized 1-aryl sulfonyl tryptamines: synthesis and pharmacological evaluation as 5-HT6 receptor ligands.
A series of N(1)-arylsulfonyl-3-(pyrrolidin-3-yl)-1H-indole and N(1)-arylsulfonyl-3-(4-chloro-2,5-dihydro-1H-pyrrol-3-yl)-1H-indole derivatives (tryptamine derivatives with rigidized side chain) have been prepared and tested for their binding affinity to 5-HT(6) receptor. Several compounds displayed potent binding affinity for the 5-HT(6) receptor when tested in in vitro binding assay. The primary SAR indicates that rigidification of dimethylamino alkyl chain at C(3) of indole carbon maintains the binding affinity to 5-HT(6)R. The lead compound N(1)-benzenesulfonyl-3-(4-chloro-1-methyl-2,5-dihydro-1H-pyrrol-3-yl)-1H-indole, 10a (K(b)=0.1 nM) has shown excellent in vitro affinity and was active in animal models of cognition like NORT and water maze.

Identification of a novel series of 3-piperidinyl-5-sulfonylindazoles as potent 5-HT6 ligands.
Cognitive dysfunction is a characteristic of various forms of dementia such as Alzheimer's disease (AD) and a core feature of schizophrenia. As part of our continuing efforts to develop agents for cognitive enhancement, we have been focused on the 5-HT(6) receptor-one of the emerging therapeutic targets in this area. Herein, we report the identification of a novel series of 3-piperidinyl-5-sulfonylindazole derivatives as potent 5-HT(6) antagonists. The synthesis and SAR of this class of compounds are reported.
