The diversity‐oriented chemistry synthesis together with the random screening approach has permitted the discovery and optimization of novel antiviral lead compounds. In this paper, a series of novel 5‐substituted‐2‐(4‐substituted phenyl)‐1,3‐benzoxazoles was synthesized and evaluated for their in vitro anti‐influenza A virus and anti‐influenza B virus activity. The activity was monitored by the MTS
面向多样性的化学合成以及随机筛选方法已允许发现和优化新型抗病毒先导化合物。本文合成了一系列新颖的5-取代-2-(4-取代苯基)-1,3-苯并恶唑,并对其体外抗甲型流感病毒和抗乙型流感病毒活性进行了评估。通过在Madin-Darby犬肾细胞中的MTS测定来监测活性。化合物7H表现出优异的抑制活性和选择性指数针对A / H3N2(EC 50 = 37.03μ米,SI> 5),它们都比参考药物奥司他韦的更高(EC 50 > 59.00μ米,SI> 1)。但是,没有化合物显示出对乙型流感病毒的抑制活性。
