Nitrobenzoates and Nitrothiobenzoates with Activity against M. tuberculosis

open access: yesMicroorganisms, 2023
Esters of weak acids have shown improved antimycobacterial activity over the corresponding free acids and nitro benzoates in particular have previously shown to have a very intriguing activity. To expand the potential of nitro-derivatives of benzoic acid
