黄酮类化合物是天然存在的植物代谢产物,能抑制SARS冠状病毒2型(SARS-CoV-2)主要蛋白酶(MPRO),而MPRO是病毒复制所必需的。在这里,我们提出了一种鉴定SARS-CoV-2 MPRO的黄酮类拮抗剂的方法。我们描述了表达和纯化MPRO的步骤,以及使用去猝灭荧光共振能量转移肽底物进行MPRO活性的动力学酶分析。然后,我们详细介绍了使用这种酶试验来测试类黄酮拮抗和可逆抑制的程序。有关该方案的使用和执行的完整细节,请参阅Lin等人的1
Flavonoids are naturally occurring metabolites of plants that can inhibit the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) main protease (Mpro), which is required for viral replication. Here, we present a protocol to identify flavonoid antagonists of the SARS-CoV-2 Mpro. We describe steps for the expression and purification of Mpro and a kinetic enzymatic assay for Mpro activity using a dequenching fluorescence resonance energy transfer peptide substrate. We then detail procedures for using this enzymatic assay to test flavonoid antagonism and reversible inhibition.For complete details on the use and execution of this protocol, please refer to Lin et al.1
