In this work, a series of novel substituted polycyclic pyridone derivatives were designed and synthesized as potent anti-influenza agents. The cytopathic effect (CPE) assay and cytotoxicity assay indicated that all of the compounds possessed potent anti-influenza virus activity and relatively low cytotoxicity; some of them inhibited the replication of influenza A virus (IAV) at picomolar concentrations
在这项工作中,设计并合成了一系列新型取代的多环吡啶酮衍生物作为有效的抗流感药物。细胞病变效应(CPE)测定和细胞毒性测定表明,所有化合物均具有有效的抗流感病毒活性和较低的细胞毒性;其中一些在皮摩尔浓度下抑制甲型流感病毒 (IAV) 的复制。进一步的研究表明,在 3 nM 的浓度下,三种化合物(10a、10d和10g)可以显着降低 IAV 的M2 RNA 量和 M2 蛋白表达,并抑制 RNA 依赖性 RNA 聚合酶 (RdRp) 的活性。其中,( R )-12-( 5H-二苯并[ a, d ][7]annulen-5-yl)-7-hydroxy-3,4,12,12a-tetrahydro-1 H -[1,4]oxazino[3,4- c ]pyrido[2,1- f ][1,2,4]triazine-6,8-dione ( 10a ) 被发现是一种很有前途的抗流感候选药物,具有良好的人肝微粒
