design and selection of a combinatorial library of pyrido[2,3-d]pyrimidin-7(8H)-ones (4) has allowed the synthesis of 121 compounds, using known and new synthetic methodologies, and the evaluation of the inhibitory activity against hepatitis C virus (HCV) genotype 1b replicon. Among these compounds, 214,10} and 242,10} presented very high activities [EC50 = 0.027 μM (CC50 = 5.3 μM) and EC50 = 0.034 μM
吡啶并[2,3 - d ]嘧啶-7(8 H)-ones(4)的组合文库的设计和选择已允许使用已知的和新的合成方法合成121种化合物,并对其抑制性进行评估抗丙型肝炎病毒(HCV)基因型1b复制子的活性。在这些化合物中,21 4,10 }和24 2,10 }表现出非常高的活性[分别为EC 50 = 0.027μM(CC 50 = 5.3μM)和EC 50 = 0.034μM(CC 50 = 13.5μM)]和高选择性指数196和397。这些值类似于EC 50索非布韦(2)(0.048μM )使用相似的方法学方法和相同的病毒亚型报道。21 4,10 }和24 2,10 }是通过比sofosbuvir短的合成路线而获得的,而24 2,10 }是非手性的,与sofosbuvir具有4个立体生成中心相反。计算机研究表明21 4,10 }和24 2,10 }通过变构位点结合抑制NS5B聚合酶。
