  通过基于结构的方法发现新型登革热病毒进入抑制剂

  摘要：

  登革热是一种由蚊子传播的病毒，近年来已成为全球主要的公共卫生问题。但是，目前对登革热疾病的治疗仅是支持性治疗，尚无特异性抗病毒药可用于控制感染。因此，最需要安全有效的抗病毒药物。登革热病毒（DENV）进入宿主细胞的过程是由其主要包膜蛋白E介导的。E蛋白的晶体结构揭示了位于结构域I和II之间铰链区的去污剂n-辛基-β- d-葡萄糖苷（β-OG）占据的疏水口袋，这对于低pH触发很重要融合所需的构象重排。因此，E蛋白是开发抗病毒剂的有吸引力的靶标。在这项工作中，我们进行了基于前期对接的虚拟筛选，以鉴定可能与β-OG结合位点结合的小分子。鉴定出了23种结构上不同的化合物，其中两个在低微摩尔范围内的EC 50值。特别地，化合物2（EC 50  = 3.1μM）显示出显着的抗病毒活性并具有良好的治疗指数。使用分子动力学模拟来尝试表征2与蛋白质E的相互作用，从而为将来的配体优化工作铺平了道路。这些研究突
