In this study, a series of 49 five-membered heterocyclic compounds containing either a pyridine- or a pyrrole-type nitrogen were synthesized and tested against Mycobacterium tuberculosis. Among them, only the 1,3,5-trisubstituted pyrazoles 5–49 exhibited minimum inhibitory concentration values in the low micromolar range, and some also exhibited an improved physicochemical profile without cytotoxic
在这项研究中,合成了49种含有吡啶或吡咯型氮的五元杂环化合物,并对结核分枝杆菌进行了测试。其中,仅在1,3,5-三取代的吡唑5 - 49个在低微摩尔范围展出最小抑制浓度值,并且一些也显示出改进的物理化学轮廓无细胞毒性效应。对三种吡唑进行了动物结核病功效模型研究,与未治疗的小鼠相比,化合物6诱导的肺细菌计数具有统计学上的显着差异。此外,为了确定该系列的目标,产生了抗性,并且全基因组测序揭示了该基因的突变。mmpL3基因。
