Abstract

本研究旨在从国家卫生健康委员会发布的《新型冠状病毒肺炎诊疗方案(试行第九版)》重型和危重型药方中筛选可能对新型冠状病毒肺炎(COVID-19)有治疗作用的活性成分,并通过其与严重急性呼吸综合征冠状病毒2(SARS-CoV-2)蛋白的相互作用阐释其作用机制。采用国际ETCM数据库和SwissADME数据库筛选3个药方中25味中药所含有的活性成分,使用PDB数据库获取SARS-CoV-2的4种蛋白质的晶体结构,采用Autodock Vina进行分子对接,使用GROMACS进行分子动力学模拟。分子结合能结果显示夏姆比奥纳、甘草素L、木犀草苷和黄芩苷等44种活性成分与SARS-CoV-2的多个靶点显示出良好的结合亲和力,而分子动力学模拟分析显示夏姆比奥纳与SARS-CoV-2的核衣壳蛋白能够更紧密地结合并发挥有效的抑制作用。本研究采用现代技术方法对中药活性成分进行研究,发现夏姆比奥纳是SARS-CoV-2核衣壳蛋白的有效抑制剂,为开发新型的抗SARS-CoV-2药物及其治疗方法提供科学的理论依据。.
