The influenza RNA polymerase complex, which consists of the three subunits PA, PB1, and PB2, is a promising target for the development of new antiviral drugs. A large library of benzofurazan compounds was synthesized and assayed against influenza virus A/WSN/33 (H1N1). Most of the new derivatives were found to act by inhibiting the viral RNA polymerase complex through disruption of the complex formed
由PA,PB1和PB2三个亚基组成的流感RNA聚合酶复合物是开发新抗病毒药物的有希望的目标。合成了庞大的苯并呋喃化合物文库,并针对流感病毒A / WSN / 33(H1N1)进行了分析。发现大多数新衍生物通过破坏亚基PA和PB1之间形成的复合物来抑制病毒RNA聚合酶复合物而发挥作用。还进行了对接研究,以阐明PA中PB1结合位点内苯并呋喃类的结合方式,并鉴定参与其作用机理的氨基酸。预测的结合姿势与生物学数据完全一致,为合理开发更有效的PA–PB1抑制剂奠定了基础。
