A new series of tacrine-coumarin hybrids linked to 1,2,3-triazole were designed, synthesized, and tested as potent dual binding site cholinesterase inhibitors (ChEIs) for the treatment of Alzheimer's disease (AD). Among them, compound 8e was the most potent anti-AChE derivative (IC50 = 27 nM) and compound 8m displayed the best anti-BChE activity (IC50 = 6 nM) much more active than tacrine and donepezil

The present invention deals with compounds of formula (I) which are novel uncharged reactivators of human acetylcholinesterase, pharmaceutical compositions comprising said compounds, and their use for reactivating human acetylcholinesterase inhibited by at least one organophosphorus nerve agent.
Design, Synthesis, biological investigations and molecular interactions of triazole linked tacrine glycoconjugates as Acetylcholinesterase inhibitors with reduced hepatotoxicity
at the amino position of tacrine were synthesized in good yield taking aid from molecular docking studies and evaluated for their in vitro AChE inhibition activity as well as hepatotoxicity. All the hybrids were found to be non-toxic on HePG2 cell line at 200 μM (100 % cell viability) as compared to tacrine (35 % cell viability) after 24 h of incubation period. Enzyme kinetic studies carried out for
found to be the most potent anti-AChE derivative (IC50 = 0.521 μM) and N-((1-(4-methoxybenzyl)-1H-1,2,3-triazol-4-yl)methyl)-1,2,3,4-tetrahydroacridin-9-amine (5j) demonstrated the best anti-BChE activity (IC50 = 0.055 μM). In vivo studies of compound 5l in Morris water maze task confirmed memory improvement in scopolamine-induced impairment. Also, molecular modeling and kinetic studies showed that compounds
设计,合成和评估了一系列新的他克林-1,2,3-三唑杂种,作为有效的双重胆碱酯酶抑制剂。大多数合成的化合物对乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BChE)均显示出良好的体外抑制活性。其中,7-氯-N -(((1-(4-甲氧基苄基)-1 H -1,2,3-三唑-4-基)甲基)-1,2,3,4-四氢ac啶-9-胺发现(5l)是最有效的抗AChE衍生物(IC 50 = 0.521μM)和N -((1-(4-甲氧基苄基)-1 H -1,2,3-三唑-4-基)甲基)-1,2,3,4-四氢ac啶9-胺(5j)具有最佳的抗BChE活性(IC 50 = 0.055μM)。莫里斯水迷宫任务中化合物5l的体内研究证实了东pol碱引起的损伤的记忆改善。同样,分子建模和动力学研究表明,化合物5l和5j同时与AChE和BChE的外围阴离子位点(PAS)和催化位点(CS)结合。
