promising tool for future treatment of memory impairment. Hence, this study has supplied highly potent 5-HT6R agents with procognitive effects, which represent an original chemical class of 1,3,5-triazines, different from widely studied sulfone and indole-like 5-HT6R ligands. The new compounds were rationally designed as modifications of lead, 4-(1-(2-chlorophenoxy)ethyl)-6-(4-methylpiperazin-1-yl)-1,3,5-triazin-2-amine
根据最近的证据,5-HT 6 R配体是未来治疗记忆障碍的有前途的工具。因此,本研究提供了具有认知作用的强效5-HT 6 R药物,它代表了1,3,5-三嗪的原始化学类别,与广泛研究的砜和吲哚样5-HT 6 R配体不同。新化合物经过合理设计,是对铅4-(1-(2-氯苯氧基)乙基)-6-(4-甲基哌嗪-1-基)-1,3,5-三嗪-2-胺的修饰(1) ,涉及引入:(i)苯环上的两个氯和(ii)将三嗪环连接到芳族醚上的各种连接基。合成,体外和对19种新化合物进行了体内生物学测试和计算机辅助SAR分析。相对于5-HT 2A R,5-HT 7 R和D 2 R,大多数新的三嗪类 化合物对5-HT 6 R表现出高亲和力(K i <100 nM)和选择性。晶体学支持的对接研究包括量子极化的配体对接(QPLD),表明氯原子可能参与不同类型的卤素键,但是,连接子的性质似乎主要影响5-HT 6 R的亲和力。4- [1-(2
