  基于片段的新型 MUS81 抑制剂的发现

  摘要：

  MUS81 是一种结构选择性核酸内切酶，可切割同源重组和有丝分裂等自然生理过程产生的各种分支 DNA 结构。因此，MUS81 能够缓解复制压力，据报道，其功能对于许多癌症的生存至关重要，特别是那些 DNA 修复机制功能失调的癌症。因此，人们对 MUS81 作为癌症药物靶点感兴趣，但目前很少有这种酶的小分子抑制剂报道，并且没有配体晶体结构可用于指导命中优化。在这里，我们报告了基于片段的新型小分子 MUS81 抑制剂的发现，其具有亚μM 生化活性。这些抑制剂被用来开发一种新型晶体系统，为小分子抑制 MUS81 提供了第一个结构见解。
