The bacterial topoisomerases DNA gyrase (GyrB) and topoisomerase IV (ParE) are essential enzymes that control the topological state of DNA during replication. The high degree of conservation in the ATP-binding pockets of these enzymes make them appealing targets for broad-spectrum inhibitor development. A pyrrolopyrimidine scaffold was identified from a pharmacophore-based fragment screen with optimization
细菌拓扑异构酶DNA回旋酶(GyrB)和拓扑异构酶IV(ParE)是在复制过程中控制DNA拓扑状态的必需酶。这些酶在ATP结合袋中的高度保守性使其成为广谱抑制剂开发的诱人靶标。从基于药效基团的片段筛选中鉴定出具有最佳潜力的吡咯并嘧啶骨架。使用选定的GyrB / ParE直系同源物进行的抑制剂复合物的结构表征有助于鉴定靶标ATP结合口袋中的重要空间,动态和组成差异,从而可以设计具有宽酶谱和双重靶向活性的高效吡咯并嘧啶抑制剂。
