Discovery of novel antitubercular drugs is an effective strategy against drug-resistant tuberculosis (TB). Our previous study has identified LPX-16j as a novel antitubercular compound. Herein, we perform a comprehensive structure–activity relationship (SAR) based on LPX-16j, indicating that the central pyrimidine ring moiety was crucial for the antitubercular activities of its derivatives, and replacing
发现新型抗结核药物是对抗耐药结核病 (TB) 的有效策略。我们之前的研究已将LPX-16j鉴定为一种新型抗结核化合物。在此,我们基于LPX-16j进行了全面的结构-活性关系 (SAR) ,表明中心嘧啶环部分对其衍生物的抗结核活性至关重要,并且用疏水取代物取代萘基具有良好的耐受性。代表性衍生物5a对 H37Ra、H37Rv 和临床耐药结核病表现出强效活性,最小抑菌浓度 (MIC) 值为 0.5–1.0 μg/mL。同时,5a在体内表现出可接受的安全性并显示出良好的口服生物利用度,值为 40.7%。差示扫描荧光、等温滴定量热法和分子对接分析表明PknB可能是化合物5a的靶标之一。总的来说,这项研究确定5a是一种有前途的新型先导化合物,有可能开发出治疗耐药结核病的候选化合物。
