retains recognition of 5-HT6R. This modification has changed the compound’s activity at 5-HT6R-operated signaling pathways from neutral antagonism to inverse agonism. The study identified compound 27 that behaves as an inverse agonist of the 5-HT6R at the Gs and Cdk5 signaling pathways. Compound 27 showed high selectivity and metabolic stability and was brain penetrant. Finally, 27 reversed scopolamine-induced
鉴于其拮抗剂在多种记忆障碍范例中的积极作用,六羟
色胺6型受体(5-HT 6 R)作为治疗认知缺陷的有希望的靶点已引起特别关注。在此,我们报道了1 H-
吡咯并[3,2- c ]
喹啉骨架的降解,以提供2-苯基-1 H-
吡咯-3-甲酰胺,它没有典型的
吲哚样骨架,并且保留了对5-HT 6 R.这种修饰已在5-HT改变了化合物的活性6 R-操作信令从中性拮抗作用途径反向激动。研究确定了化合物27,可作为5-HT 6的反向激动剂在Gs和Cdk5信号通路中的R。化合物27显示出高选择性和代谢稳定性,并且是脑渗透剂。最后,在新的物体识别测试中,有27种逆转了东pol碱所致的记忆力下降,并在大鼠的注意转移中表现出认知功能。根据这些发现,可以考虑将27种化合物作为一种新的认知增强剂进行进一步评估,而2-苯基-1 H-
吡咯-3-羧酰胺可以用作设计5-HT 6 R反向激动剂的模板。
