ose oxidase (DprE1) is a promising target for treating tuberculosis (TB). Currently, most novel DprE1 inhibitors are discovered through high-throughput screening, while computer-aided drug design (CADD) strategies are expected to promote the discovery process. In this study, with the aid of structure-based virtual screening and computationally guided design, a series of novel scaffold N-(1-(6-oxo-1
十异戊二烯基磷酰基-β- d-核糖氧化酶 (DprE1) 是治疗结核病 (TB) 的一个有前景的靶点。目前,大多数新型DprE1抑制剂都是通过高通量筛选发现的,而计算机辅助药物设计(CADD)策略有望促进发现过程。本研究借助基于结构的虚拟筛选和计算引导设计,鉴定出一系列具有显着抗分枝杆菌活性的新型支架N- (1-(6-氧代-1,6-二氢嘧啶)-吡唑)乙酰胺衍生物。其中,化合物LK-60和LK-75能够有效抑制Mtb的增殖,MIC Mtb值为0.78-1.56 μM,与异烟肼相当,远优于II期候选TBA-7371 (MIC Mtb = 12.5 μM) )。 LK-60也是迄今为止最活跃的源自CADD的DprE1抑制剂。进一步的研究证实它们与 DprE1 具有高亲和力,对肠道微生物群和人类细胞具有良好的安全性,以及与利福平或乙胺丁醇的协同作用,表明它们具有广泛的临床应用潜力。
