新冠肺炎大流行造成的全球公共卫生和社会经济后果凸显了通过提供快速疾病预防和治疗战略来加强对病毒疾病暴发的准备的重要性。冠状病毒的NSP3大结构域包括SARS-CoV-2,由于其在病毒复制和宿主致病性中的关键作用,被确定为抗病毒药物开发的潜在靶点之一。通过将虚拟筛选和生物物理筛选相结合,我们发现了几个实验性的小分子和FDA批准的药物作为NSP3大结构域的抑制剂。对作用物质的模拟表征和确定包括抗生素化合物氨曲南在内的大结构域活性部位的结合模式的结晶学研究,提供了有价值的构效关系信息,支持目前的方法,并为NSP3大结构域抑制剂的开发开辟了新的途径。
The worldwide public health and socioeconomic consequences caused by the COVID-19 pandemic highlight the importance of increasing preparedness for viral disease outbreaks by providing rapid disease prevention and treatment strategies. The NSP3 macrodomain of coronaviruses including SARS-CoV-2 is among the viral protein repertoire that was identified as a potential target for the development of antiviral agents, due to its critical role in viral replication and consequent pathogenicity in the host. By combining virtual and biophysical screening efforts, we discovered several experimental small molecules and FDA-approved drugs as inhibitors of the NSP3 macrodomain. Analogue characterisation of the hit matter and crystallographic studies confirming binding modes, including that of the antibiotic compound aztreonam, to the active site of the macrodomain provide valuable structure–activity relationship information that support current approaches and open up new avenues for NSP3 macrodomain inhibitor development.
