摘要

由于目前的大流行，研究人员正在寻找能够抑制或阻止SARS-CoV-2的植物候选物。SARS-CoV-2的主要蛋白酶(Mpro)和刺突糖蛋白(S)都受到植物中发现的生物活性化合物的抑制，这些活性化合物通过将它们对接在一起起作用。Mpro蛋白6LU7(配合抑制剂N3)和5C3N(空间群C2221)进行对接研究。对接引擎采用PyRx和AutoDock Vina软件。从人工整理的IMPPAT数据库中选择22种已确定的植物成分，根据它们的抗病毒作用。对接研究表明，植物成分β-amyrin (-8.4 kcal/mol)、withaferin A (-8.3 kcal/mol)、齐墩果酸(-7.8 kcal/mol)和patentiflorin A (-8.1 kcal/mol)对5C3N Mpro蛋白的抑制效果最好，而kuwanon L (-7.1 kcal/mol)、β-amyrin (-6.9 kcal/mol)、齐墩果酸(-6.8 kcal/mol)、葫芦素D (-6.5 kcal/mol)和槲皮素(-6.5 kcal/mol)对6LU7 Mpro蛋白的抑制效果最好。使用SwissDock检测所有化合物的ADMET特性。目前的研究报告表明，植物成分与对接评分将有助于未来抗Covid-19药物的开发。

Molecular docking studies on the phytoconstituents as therapeutic leads against SARS-CoV-2

Because of the present pandemic researchers are seeking for phytocandidates that can inhibit or stop SARS-CoV-2. The main protease (Mpro) of SARS-CoV-2 and spike glycoprotein (S) are both suppressed by bioactive compounds found in plants that work by docking them together. The Mpro proteins 6LU7 (complex with an inhibitor N3) and 5C3N (space group C2221) were employed in docking research. PyRx and AutoDock Vina software were used as docking engine. 22 identified phytoconstituents were selected from IMPPAT, a manually curated database, on the basis of their antiviral effects. Docking studies showed that phytoconstituents β-amyrin (-8.4 kcal/mol), withaferin A (-8.3 kcal/mol), oleanolic acid (-7.8 kcal/mol), and patentiflorin A (-8.1 kcal/mol) had the best results against 5C3N Mpro protein whereas kuwanon L (-7.1 kcal/mol), β-amyrin (-6.9 kcal/mol), oleanolic acid (-6.8 kcal/mol), cucurbitacin D (-6.5 kcal/mol), and quercetin (-6.5 kcal/mol) against 6LU7 Mpro protein. All the compounds were examined for their ADMET characteristics using SwissDock. Present research reports that the phytoconstituents along with docking score will be helpful for future drug development against Covid-19.
