Abstract

We herein report the facile synthesis of a series of 3,5-substituted-1,2,4-oxadiazole derivatives 9a-e and 10a-e in good to excellent yields by employing NMI-MsCl mediated amide bond formation reaction. The anti-inflammatory potential of the newly synthesized compounds were evaluated by anti-denaturation assay using diclofenac sodium as the reference drug. The compounds 9a and 9d demonstrated promising activity profile when compared to the reference standard. The SAR and molecular docking studies were also carried out for obtaining more details about the profound activity profile of the synthesized molecules. The synthesized compounds were docked against two target proteins TGF-β and IL-1 by AutoDock vina and Auto Dock 4.2.

摘要

我们在此报告了一系列 3,5-取代-1,2,4-噁二唑衍生物 9a-e 和 10a-e 的简便合成方法,通过采用 NMI-MsCl 介导的酰胺键形成反应,可获得良好至优异的产率。新合成化合物的抗炎潜力通过使用双氯芬酸钠作为参考药物的抗变性测定来评估。与参考标准相比,化合物 9a 和 9d 表现出有希望的活性特征。还进行了 SAR 和分子对接研究,以获得有关合成分子的深刻活性特征的更多详细信息。通过 AutoDock vina 和 Auto Dock 4.2 将合成化合物对接至两个靶蛋白 TGF-β 和 IL-1。
