The COVID-19 pandemic progresses unabated in many regions of the world. An effective antiviral against SARS-CoV-2 that could be administered orally for use following high-risk exposure would be of substantial benefit in controlling the COVID-19 pandemic. Herein, we show that MK-4482, an orally administered nucleoside analog, inhibits SARS-CoV-2 replication in the Syrian hamster model. The inhibitory effect of MK-4482 on SARS-CoV-2 replication is observed in animals when the drug is administered either beginning 12 h before or 12 h following infection in a high-risk exposure model. These data support the potential utility of MK-4482 to control SARS-CoV-2 infection in humans following high-risk exposure as well as for treatment of COVID-19 patients.
新冠疫情在世界许多地区仍在持续蔓延。一种有效的抗SARS-CoV-2病毒药物,若能口服并用于高风险暴露后的预防,将对控制新冠疫情大有裨益。在此,我们表明,口服核苷类似物MK-4482在叙利亚仓鼠模型中可抑制SARS-CoV-2复制。在高风险暴露模型中,于感染前12小时或感染后12小时开始给药,均可观察到MK-4482对动物体内SARS-CoV-2复制的抑制作用。这些数据支持了MK-4482在高风险暴露后控制人类SARS-CoV-2感染以及治疗新冠患者方面的潜在效用。
