As part of a project aimed at developing new agents for potential application in Alzheimer's disease, a new series of acetophenone derivatives which possess alkylamine side chains were designed, synthesized and assayed as acetylcholinesterase (AChE) inhibitors that could simultaneously bind to the peripheral and catalytic sites of the enzyme. The compounds were synthesized, and the inhibitory activities toward AChE and butyrylcholinesterase (BuChE) in vitro were determined using a modified Ellman method. Of the compounds tested, 6 derivatives were found to inhibit AChE in the micromolar range. The best compound, 2e, had an IC50 of 0.13 μM. A detailed molecular modeling study was performed to explore the interaction of 2e with AChE.
作为一个旨在开发阿尔茨海默病潜在应用新药的项目,设计、合成并评估了一系列具有烷基胺侧链的乙酰苯酮衍生物,作为能同时结合酶的外周位点和催化位点的乙酰胆碱酯酶(AChE)抑制剂。这些化合物被合成,并使用改良的埃尔曼法确定其对AChE和丁酰胆碱酯酶(BuChE)的抑制活性。在测试的化合物中,发现有6种衍生物在微摩尔范围内抑制了AChE。最佳化合物2e的IC50为0.13 μM。进行了详细的分子建模研究,以探讨2e与AChE的相互作用。
