controlling Influenza A virus (IAV) infections, novel structural antivirus small-molecule drugs with new mechanisms of action for treating IAV are highly desirable. Herein, we describe a modular biomimetic strategy to expeditiously achieve a new class of macrocycles featuring oxime, which might target the hemagglutinin (HA)-mediated IAV entry into the host cells. SAR analysis revealed that the size
尽管疫苗接种仍然是控制甲型流感病毒(IAV)感染的普遍预防手段,但具有新作用机制的新型结构抗病毒小分子药物治疗 IAV 仍然非常令人期待。在此,我们描述了一种模块化仿生策略,以快速实现一类以肟为特征的新型大环化合物,该大环化合物可能靶向血凝素(HA)介导的IAV进入宿主细胞。 SAR 分析表明,大环化合物的大小和连接基在提高效力方面发挥着重要作用。特别是, 37作为14元大环肟,对IAV H1N1表现出有效的抑制活性,EC 50值为23 nM,细胞毒性较低,可减轻H1N1感染后的细胞病变效应,明显保护细胞存活。此外, 37在体外与神经氨酸酶抑制剂奥司他韦表现出显着的协同活性。
