摘要:

目的:从不同的印度药用植物和饮食来源中筛选出186种生物学上重要的苯丙素类和聚酮化合物,以筛选出与SARS-CoV-2治疗靶蛋白活性位点结合的潜在化合物。方法:利用Autodock Vina进行分子对接研究。从SwissADME服务器预测化合物的计算机模拟ADMET和药物样性质。测试结果:对186个化合物与SARS-CoV-2治疗靶蛋白(Mpro、PLpro、RdRp、SGp和ACE 2)进行了分子对接研究,发现40个化合物与SARS-CoV-2治疗靶蛋白结合在活性位点上,对接分数大于-8.0 kcal/mol。结论:基于对40个化合物的计算机ADMET研究和药物相似性预测,我们在186个具有重要生物学意义的苯丙素类和聚酮化合物中,提出矮牵牛素、黄芩素、矢车菊素、7-羟基-3 ',4'-亚甲二氧基黄烷、槲皮素和鞣花酸为潜在先导化合物,可进一步进行生物学和临床研究,以制定COVID-19的治疗方法。

英文摘要:

Objective: Total 186 biologically important phenylpropanoids and polyketides compounds from different Indian medicinal plants and dietary sources were screened to filter potential compounds that bind at the active site of the therapeutic target proteins of SARS-CoV-2. Method: The molecular docking studies were carried out by using the Autodock Vina. The in silico ADMET and drug-likeness properties of the compounds were predicted from SwissADME server. Result: The molecular docking study of the 186 compounds with the therapeutic target proteins (Mpro, PLpro, RdRp, SGp and ACE2) of SARS-CoV-2 resulted 40 compounds that bind at the active site with dock score above -8.0 kcal/mol. Conclusion: Based on the in silico ADMET study and drug-likeness prediction of 40 compounds, we proposed petunidin, baicalein, cyanidin, 7-hydroxy-3',4'-methylenedioxyflavan, quercetin and ellagic acid among the 186 biologically important phenylpropanoids and polyketides as potential lead compounds, which can further be investigated pharmacologically and clinically to formulate therapeutic approaches for the COVID-19.
