In this study, we synthesized novel nitro quinolone‐based compounds and tested them in vitro against a panel of Gram‐positive and Gram‐negative pathogens including Mycobacterium tuberculosis (MTB), Pseudomonas aeruginosa , Acinetobacter baumannii , Klebsiella pneumonia , Staphylococcus aureus , and Escherichia coli for antibacterial activities and also against HeLa cells for overt cytotoxicity. Compound 8e was identified as a non‐toxic, potent hit with selective activity (MIC90 ˂ 0.24 µm ) against MTB. 8e , however, showed no activity against DprE1 mutant, suggesting DprE1 as the likely target for this compound class.

6-Nitro-1-benzylquinolones 表现出特定的抗结核活性。

在这项研究中,我们合成了新型硝基喹诺酮类化合物,并针对一系列革兰氏阳性和革兰氏阴性病原体进行了体外测试,包括结核分枝杆菌(MTB)、铜绿假单胞菌鲍曼不动杆菌肺炎克雷伯菌金黄色葡萄球菌埃希氏菌大肠杆菌具有抗菌活性,也针对 HeLa 细胞具有明显的细胞毒性。化合物8e被鉴定为对 MTB具有选择性活性 (MIC 90  ˂ 0.24 µm )的无毒、有效打击。8e然而,对 DprE1 突变体没有活性,表明 DprE1 可能是该化合物类别的目标。
