5-disubstituted 1,3,4-oxadiazole derivatives of (E)-2-aryl-5-(3,4,5-trimethoxystyryl)-1,3,4-oxadiazoles 4(a–o) and (E)-2-aryl-5-(2-benzo[d][1,3]dioxol-5-yl)vinyl)-1,3,4-oxadiazoles 5(a–q) were synthesized and evaluated for their in vitro acetylcholinesterase (AChE) inhibitory activity. All the synthesized compounds exhibited moderate to good inhibitory activity toward the AChE enzyme. Among the oxadiazole derivatives
(E)-2-芳基-5-(3,4,5-三甲氧基苯乙烯基)-1,3,4-恶二唑4(a - o)的2,5-二取代的1,3,4-恶二唑衍生物库合成了(E)-2-芳基-5-(2-苯并[d] [1,3]二恶酚-5-基)乙烯基)-1,3,4-恶二唑5(a – q)并评估了它们的体外乙酰胆碱酯酶(AChE)抑制活性。所有合成的化合物均对AChE酶表现出中等至良好的抑制活性。在所研究的恶二唑衍生物中,化合物4a,4g,5c和5m(IC 50分别测定24.89、13.72、37.65和19.63μM的AChE是AChE抑制剂。使用GOLD对接软件检查了这些化合物的分子蛋白质-配体对接研究,确定了它们的结合构象,并且还建立了有效衍生物的同时相互作用模式。
