inhibitory activity of the novel modified tacrines 5, and the compound derivatives from cyclohexanone (4b) showed the best AChE and BChE inhibitory activities. Specifically, 1,2,3-triazolo[4,5-b]aminoquinolines 5bb obtained from 3-methyl-carbonitrile (3b) showed the highest AChE (IC50 = 12.01 μM), while 5ib from 3-sulfonamido-carbonitrile (3i) was the most significant inhibitor for BChE (IC50 = 1.78 μM).

通过与容易获得的前体(即, 3-烷基(芳基)-5-氨基-1,2,3-三唑-4-甲腈( 3 ))和选定的五元环、六元环和七元环的环烷酮( 4 )。我们评估了新型修饰的他克林5的 AChE 和 BChE 抑制活性,环己酮化合物衍生物 ( 4b ) 显示出最好的 AChE 和 BChE 抑制活性。具体而言,从 3-甲基-甲腈 ( 3b ) 获得的1,2,3-三唑并[4,5- b ]氨基喹啉5bb显示出最高的 AChE (IC 50 = 12.01 μM),而从 3-磺酰胺基-甲腈 ( 3i ) 获得的5ib显示出最高的 AChE (IC 50 = 12.01 μM) ) 是 BChE 最显着的抑制剂 (IC 50 = 1.78 μM)。一般来说,化合物5的抑制效力弱于纯他克林参考品,我们的研究结果可能有助于设计和开发基于修饰他克林的新型抗胆碱酯酶药物。
