在开发SARS-CoV-2治疗药物的紧急运动中,天然产物一直是新先导化合物的重要来源。我们在本文中使用针对SARS-CoV-2木瓜蛋白酶样蛋白酶(PLpro)的高通量筛选确定了两种天然产物银杏酸和漆树酸作为抑制剂。此外,我们的研究表明,这两个命中化合物是双重抑制剂靶向SARS-CoV-2 3-糜蛋白酶样蛋白酶(3CLpro)除了PLpro。使用酶动力学的作用机制研究进一步表征了这两种化合物作为针对3CLpro和PLpro的不可逆抑制剂。值得注意的是,这两种鉴定的化合物在无毒浓度下抑制SARS-CoV-2体外复制。我们的发现提供了两种新的天然产物作为有前途的SARS-CoV-2抗病毒药物。
In the urgent campaign to develop therapeutics against SARS-CoV-2, natural products have been an important source of new lead compounds. We herein identified two natural products, ginkgolic acid and anacardic acid, as inhibitors using a high-throughput screen targeting the SARS-CoV-2 papain-like protease (PLpro). Moreover, our study demonstrated that the two hit compounds are dual inhibitors targeting the SARS-CoV-2 3-chymotrypsin-like protease (3CLpro) in addition to PLpro. A mechanism of action study using enzyme kinetics further characterized the two compounds as irreversible inhibitors against both 3CLpro and PLpro. Significantly, both identified compounds inhibit SARS-CoV-2 replication in vitro at nontoxic concentrations. Our finding provides two novel natural products as promising SARS-CoV-2 antivirals.
