instances of resistance to frontline TB drugs there is the need to develop novel strategies to fight the worldwide TB epidemic. Boosting the effect of the existing second-line antibiotic ethionamide by inhibiting the mycobacterial transcriptional repressor protein EthR is an attractive therapeutic strategy. Herein we report the use of a fragment based drug discovery approach for the structure-guided systematic
随着对一线结核病药物耐药性的不断增加,需要制定新的战略来对抗全球结核病流行。通过抑制分枝杆菌转录抑制蛋白 EthR 来增强现有二线抗生素乙硫异烟胺的作用是一种有吸引力的治疗策略。在这里,我们报告了使用基于片段的药物发现方法来进行结构引导的两个片段分子的系统合并,每个片段分子与结核分枝杆菌的 EthR 疏水腔结合两次。这些一起填满了 EthR 的整个绑定口袋。我们详细阐述了这些片段命中并开发了小分子抑制剂,其在体外的效力比初始片段提高了 100 倍。
