关注的SARS-CoV-2变体(VoC)的出现加剧了COVID-19大流行。目前可用的单克隆抗体和疫苗似乎对这些VoC中的一些具有降低的功效。靶向SARS-CoV-2保守蛋白的抗病毒药物不太可能受到VoC突变的影响,因此应该对新出现的变体有效。我们在此研究了目前处于2期临床试验的莫努匹拉韦在感染武汉毒株或B.1.1.7和B.1.351变异株的仓鼠中的疗效。事实证明,莫努匹拉韦对每种变体的感染都有效,因此可能具有对抗当前和未来新兴VOC的潜力。
The emergence of SARS-CoV-2 variants of concern (VoCs) has exacerbated the COVID-19 pandemic. Currently available monoclonal antibodies and vaccines appear to have reduced efficacy against some of these VoCs. Antivirals targeting conserved proteins of SARS-CoV-2 are unlikely to be affected by mutations arising in VoCs and should therefore be effective against emerging variants. We here investigate the efficacy of molnupiravir, currently in phase 2 clinical trials, in hamsters infected with Wuhan strain or B.1.1.7 and B.1.351 variants. Molnupiravir proved to be effective against infections with each of the variants and therefore may have potential combating current and future emerging VoCs.
