unique glycan-binding ability of chemically synthesized boronic acid derivatives makes them emerging candidates for developing anti-influenza A virus (IAV) drugs. Herein we report the synthesis and the anti-IAV activities of three series of novel boronic acid-modified quindoline derivatives both in vitro and in vivo. Boronic acid-modified compounds 6a and 7a effectively prevented the entry of virus RNP
化学合成的硼酸衍生物独特的聚糖结合能力使其成为开发抗甲型流感病毒(IAV)药物的新兴候选药物。在本文中,我们报道了在体内和体外三个系列的新型硼酸修饰的喹啉衍生物的合成和抗IAV活性。硼酸修饰的化合物6a和7a有效地阻止了病毒RNP进入细胞核,降低了被IAV感染的细胞中的病毒滴度,还抑制了病毒神经氨酸酶的活性。化合物7a具有广泛的抗病毒谱,能够抑制细胞NF-κB和MAPK信号传导途径来阻断IAV感染。更重要的是,用化合物7a治疗的被IAV感染的小鼠与使用流行的抗IAV药物奥司他韦治疗的小鼠相比,其存活率更高。因此,我们的研究不仅提供了抗病毒的临床前候选药物,而且为进一步研究和开发硼酸修饰的抗IAV药物提供了有用的信息。
