A series of 2′-hydroxy- and 2′-hydroxy-4′,6′-dimethoxychalcones was synthesised and evaluated as inhibitors of human acetylcholinesterase (AChE). The majority of the compounds were found to show some activity, with the most active compounds having IC50 values of 40–85 µM. Higher activities were generally observed for compounds with methoxy substituents in the A ring and halogen substituents in the
合成了一系列 2'-羟基-和 2'-羟基-4',6'-二甲氧基查尔酮,并将其作为人乙酰胆碱酯酶 (AChE) 的抑制剂进行评估。发现大多数化合物具有一定的活性,活性最强的化合物的 IC50 值为 40–85 µM。对于在 A 环中具有甲氧基取代基和在 B 环中具有卤素取代基的化合物,通常观察到更高的活性。对最活跃的化合物的动力学研究表明,它们作为混合型抑制剂,这与分子模型研究的结果一致,这表明它们与外周阴离子位点和 AChE 峡谷区域的残基相互作用。
