Modulators of the serotonin 5-HT6 receptor (5-HT6R) offer a promising strategy for the treatment of the cognitive deficits that are associated with dementia and Alzheimer's disease. Herein, we report the design, synthesis, and characterization of a novel class of 5-HT6R antagonists that is based on the 1H-pyrrolo[3,2-c]quinoline core. The most active compounds exhibited comparable binding affinity
血清素5-HT6受体(5-HT6R)的调节剂为治疗与痴呆和阿尔茨海默氏病相关的认知缺陷提供了一种有前途的策略。在这里,我们报告基于1H-吡咯并[3,2-c]喹啉核心的一类新型的5-HT6R拮抗剂的设计,合成和表征。最具活性的化合物对参考化合物SB-742457表现出可比的结合亲和力,并且选择性显着提高。铅的优化导致对(S)-1-[(3-氯苯基)磺酰基] -4-(吡咯烷-3-基-氨基)-1H-吡咯并[3,2-c]喹啉的鉴定(14)( Ki = 3 nM,Kb = 0.41 nM)。5-HT6R在Gs信号转导上的组成活性的药理学表征表明,14充当中性拮抗剂,而SB-742457被归类为反向激动剂。化合物14和SB-742457均可逆转苯环利定诱发的记忆缺陷,并在NOR任务中在无认知障碍的动物(3 mg / kg)中表现出明显的认知特性。化合物14和SB-742457在Vogel试验中也具有活性,但14的抗焦虑作用高2倍(MED
