Disclosed in the disclosure are a pyrazolo [1,5-a] pyrideine compound with structural features as shown in formula (I) or a pharmaceutically acceptable salt, stereoisomer or prodrug molecule thereof and a use thereof. Such compounds have a good in vitro antituberculosis activity, and the minimal inhibitory concentration (MIC) of the compounds is lower than 0.1 μg/mL and partially achieves 0.01 μg/mL, and have a very strong inhibiting effect on clinically selected multi-drug resistant tuberculosis (MDR-TB) strains. In an in vivo experiment, the pyrazolo[1,5-a] pyrideine compounds of the present disclosure can effectively scavenge the infectious dose of H37Ra in a mouse body at 20 mg/kg/d does, thereby being a new type of antituberculosis compound.
本发明公开了具有式(I)所示结构特征的吡唑并[1,5-a]吡啶化合物或其药学上可接受的盐、立体异构体或原药分子及其用途。此类化合物具有良好的体外抗结核活性,其最小抑菌浓度(MIC)低于 0.1 μg/mL,部分达到 0.01 μg/mL,对临床筛选出的耐多药结核菌株(MDR-TB)具有很强的抑制作用。在体内实验中,本公开的吡唑并[1,5-a]吡啶化合物在20 mg/kg/d的剂量下可以有效清除小鼠体内H37Ra的感染剂量,从而成为一种新型的抗结核化合物。
