coumarin derivatives, substituted at 3 and 7 positions with aminoalkoxy groups, are synthesized, characterized, and screened. The effect of amine substituents and the length of cross-linker are investigated in acetyl- and butyrylcholinesterase (AChE and BuChE) inhibition. Target compounds show moderate to potent inhibitory activities against AChE and BuChE. 3-(3,4-Dichlorophenyl)-7-[4-(diethylamino)but
合成,表征和筛选了两类在3和7位被氨基烷氧基取代的新型香豆素衍生物。在乙酰基和丁酰胆碱酯酶(AChE和BuChE)抑制作用中研究了胺取代基的影响和交联剂的长度。目标化合物显示出对AChE和BuChE的中度至强效抑制活性。3-(3,4-二氯苯基)-7- [4-(二乙基氨基)丁氧基] -2H-铬-2--2-(4y)被确定为最有效的抗AChE化合物(IC50 = 0.27μm)。动力学和分子建模研究证实,化合物4y以混合型方式起作用,并与AChE的催化活性位(CAS)和外围阴离子位(PAS)同时相互作用。此外,化合物4y以44的比例阻断β-淀粉样蛋白(Aβ)的自聚集。
