Our previous studies have shown that cholesterol-conjugated, peptide-based pan-coronavirus (CoV) fusion inhibitors can potently inhibit human CoV infection. However, only palmitic acid (C16)-based lipopeptide drugs have been tested clinically, suggesting that the development of C16-based lipopeptide drugs is feasible. Here, we designed and synthesized a C16-modified pan-CoV fusion inhibitor, EK1-C16, and found that it potently inhibited infection by SARS-CoV-2 and its variants of concern (VOCs), including Omicron, and other human CoVs and bat SARS-related CoVs (SARSr-CoVs). These results suggest that EK1-C16 could be further developed for clinical use to prevent and treat infection by the currently circulating MERS-CoV, SARS-CoV-2 and its VOCs, as well as any future emerging or re-emerging coronaviruses.

我们之前的研究表明，胆固醇缀合的基于肽的泛冠状病毒（CoV）融合抑制剂能够有效地抑制人类 CoV 感染。然而，仅对棕榈酸（C16）为基础的脂肽药物进行了临床测试，这表明 C16 为基础的脂肽药物的开发是可行的。在这里，我们设计并合成了一种 C16 修饰的泛 CoV 融合抑制剂 EK1-C16，并发现它能够有效地抑制 SARS-CoV-2 及其关注变种（VOCs），包括奥密克戎，以及其他人类 CoV 和蝙蝠 SARS 相关 CoV（SARSr-CoV）的感染。这些结果表明，EK1-C16 可以进一步开发用于临床，以预防和治疗目前流行的 MERS-CoV、SARS-CoV-2 及其 VOCs 以及任何未来新出现或重新出现的冠状病毒的感染。
