afforded the title compounds 12–15. Molecular docking study of the title compounds 12–15 was carried out against neuraminidase as the target enzyme, in an attempt to understand the mechanism of action of the tested compounds as potential neuraminidase inhibitors. Molecular docking of the target compounds showed that all tested compounds bind to the active site of neuraminidase, with moderate to high binding
以L-酒石酸为原料合成了一系列新型吡咯并[2,1-b][1,3]恶氮杂-8,9-二醇衍生物12-15,将其转化为酸酐,然后在二甲苯中与烯丙胺反应生成得到酰亚胺 2。目标分子 12-15 是通过使用 Grubbs 催化剂通过闭环复分解反应获得的,然后是羰基的还原和羟基的脱保护。最后,双键的催化氢化得到标题化合物 12-15。以神经氨酸酶为靶标酶对标题化合物 12-15 进行了分子对接研究,试图了解被测化合物作为潜在神经氨酸酶抑制剂的作用机制。目标化合物的分子对接表明,所有测试化合物都与神经氨酸酶的活性位点结合,具有中到高的结合能。检查了化合物 12-15 对 H5N1 病毒的抗病毒活性 (A/chicken/Egypt/1/2008)。磷酸奥司他韦用作抗病毒活性的对照。结果表明,化合物 12 (EC50 = 0.016 μg/mL) 表现出有效的抗流感 (H5N1) 活性,与奥司他韦 (EC50
