SARS-CoV-2病毒的出现导致了世界范围的大流行,但有效的抗病毒治疗并不广泛。为了改善治疗方案,我们进行了高通量筛选,以发现阻断SARS-CoV-2感染的化合物。使用最低致病性人β冠状病毒(OC 43)感染生理相关的人肺成纤维细胞(MRC 5),以促进在临床前模型中快速发现抗病毒药物。对600多种化合物进行了全面分析,每种化合物排列在10个剂量点上。我们的筛选发现了几种FDA批准的可以减弱OC 43和SARS-CoV-2病毒复制的药物,包括拉帕替尼,多拉匹莫德和17-AAG。重要的是,拉帕替尼抑制SARS-CoV-2 RNA复制超过5万倍。此外,拉帕替尼和多拉匹莫德都可以与Remdesivir组合,以提高细胞中的抗病毒活性。这些发现揭示了新的治疗途径,可以限制SARS-CoV-2感染。
The emergence of SARS-CoV-2 virus has resulted in a worldwide pandemic, but effective antiviral therapies are not widely available. To improve treatment options, we conducted a high-throughput screen to uncover compounds that block SARS-CoV-2 infection. A minimally pathogenic human betacoronavirus (OC43) was used to infect physiologically-relevant human pulmonary fibroblasts (MRC5) to facilitate rapid antiviral discovery in a preclinical model. Comprehensive profiling was conducted on more than 600 compounds, with each compound arrayed across 10 dose points. Our screening revealed several FDA-approved agents that can attenuate both OC43 and SARS-CoV-2 viral replication, including lapatinib, doramapimod, and 17-AAG. Importantly, lapatinib inhibited SARS-CoV-2 RNA replication by over 50,000-fold. Further, both lapatinib and doramapimod could be combined with remdesivir to improve antiviral activity in cells. These findings reveal novel therapeutic avenues that could limit SARS-CoV-2 infection.
