The interactions of two crucial proteins of COVID-19 have been investigated with potential antiviral compounds from using quantum chemical, molecular docking and dynamic methods. The results of the present investigation show that ellagic acid and apigenin possess the highest binding affinities of -7.1 and -6.5 Kcal.molagainst nsp9 and -6.9 and -7.1 Kcal.mol against nsp10, respectively. The dynamic behavior of individual proteins and their respective best docked ligand-protein complexes are also studied at 30 ns timescale. Both of these compounds also show the highest intestinal absorption and total clearance rate as compared to the other compounds under present investigation without any toxicity.
利用量子化学、分子对接和动力学方法,研究了新冠病毒两种关键蛋白与潜在抗病毒化合物之间的相互作用。本研究结果表明,鞣花酸和芹菜素对nsp9的结合亲和力最高,分别为-7.1和-6.5千卡/摩尔,对nsp10的结合亲和力分别为-6.9和-7.1千卡/摩尔。还在30纳秒的时间尺度上研究了单个蛋白质及其各自最佳对接的配体-蛋白质复合物的动力学行为。与本研究中的其他化合物相比,这两种化合物均显示出最高的肠道吸收率和总清除率,且无任何毒性。
