function in the replication, spread, and pathogenesis of influenza virus by inhibiting the host innate immune response. Here we report the discovery and optimization of novel pyrazolopyridine NS1 antagonists that can potently inhibit influenza A/PR/8/34 replication in MDCK cells, rescue MDCK cells from cytopathic effects of seasonal influenza A strains, reverse NS1-dependent inhibition of IFN-β gene
非结构蛋白1(NS1)通过抑制宿主先天免疫应答,在流感病毒的复制,传播和发病机理中起着至关重要的作用。在这里,我们报告发现和优化新型吡唑并吡啶NS1拮抗剂,它们可以有效抑制MDCK细胞中的流感A / PR / 8/34复制,从季节性流感A株的细胞病变作用中拯救MDCK细胞,逆转NS1依赖性的IFN-β抑制作用基因表达,并抑制表达NS1的酵母中的缓慢生长表型。这些吡唑并吡啶将使研究人员能够研究感染期间的NS1功能,以及在下一代流感感染治疗中如何利用拮抗剂。
