series of 2,4-disubstituted quinazoline derivatives were designed, synthesized and their antiviral activities against influenza A virus were evaluated. Nine compounds (10a2, 16a, 16e, 16i, 16j, 16n, 16o, 16p and 16r) showed potent activity against influenza A virus (IAV) with IC50 at the low-micromole level (1.29–9.04 μM). Particularly, 16e and 16r possess good anti-IAV activity (IC50: 1.29 μM and 3.43 μM
由于高致病性和耐药性的流感病毒的出现,迫切需要开发更有效的抗流感药。在此,设计,合成了一系列2,4-二取代的喹唑啉衍生物,并评估了它们对甲型流感病毒的抗病毒活性。九种化合物(10A2,16A,16E,16I,16J,16N,16O,16P和16R)显示针对A型流感病毒(IAV)与IC有效的活性50在低级别微摩尔(μM1.29-9.04)。特别是16e和16r具有良好的抗IAV活性(IC 50分别为1.29μM和3.43μM)和可接受的细胞毒性,并抑制病毒RNA的转录和复制。结合合理的16e PK曲线,这些结果表明它们有望用作进一步研究的潜力。
