  Design, Synthesis, and Biological Evaluation of Pyrazolo[1,5-a]pyridine-3-carboxamides as Novel Antitubercular Agents

  摘要：

  A series of pyrazolo[1,5-a]pyridine-3-carboxamide derivatives were designed and synthesized as new anti-Mycobacterium tuberculosis (Mtb) agents. The compounds exhibit promising in vitro potency with nanomolar MIC values against the drug susceptive H37Rv strain and a panel of clinically isolated multidrug-resistant Mtb (MDR-TB) strains. One of the representative compounds (5k) significantly reduces the bacterial burden in an autoluminescent H37Ra infected mouse model, suggesting its promising potential to be a lead compound for future antitubercular drug discovery.

  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.
