molecular docking studies were carried out. HIGHLIGHTS 3-benzyloxyflavone analogues were designed, synthesized and characterized. The target molecules (1–10) were evaluated for their inhibitory potential against AChE and BChE inhibitory activities. Limited structure-activity relationship was developed based on the different substituent patterns on aryl part. Molecular docking studies were conducted to
摘要 在该协议中,一系列 3-苄氧基黄酮衍生物已被设计、合成、表征和体外研究作为胆碱酯酶抑制剂。研究结果表明,所有合成的目标化合物 ( 1-10 ) 都是有效的乙酰胆碱酯酶 (AChE) 和丁酰胆碱酯酶 (BChE) 双重抑制剂,具有不同的 IC 50值。相比之下,它们对 AChE 的作用比 BChE 更有效。值得注意的是,除该系列中,化合物2被确定为既乙酰胆碱酯酶的最活跃的抑制剂(IC 50 = 0.05±0.01μM)和的BChE(IC 50 = 0.09±0.02μM)相对于标准多奈哌齐(IC 50= 0.09 ± 0.01(AChE)和 0.13 ± 0.04 μM(BChE)。此外,与标准品相比,衍生物5 (IC 50 = 0.07 ± 0.02 μM) 和10 (0.08 ± 0.02 μM) 对 AChE 表现出最高的选择性抑制。初步建立了构效关系,因此发现这些化合物的胆碱酯酶抑制活性高度依赖于
