Abstract

In this work we report the tuberculostatic profile of a series of 5-phenyl-1,3,4-thiadiazole-2-arylhydrazone derivatives (1a-m). The evaluation of their in vitro antibacterial activity against Mycobacterium tuberculosis H37Rv was expressed as the minimum inhibitory concentration (MIC) in μg/mL. The compounds 1g and 1h exhibited inhibitory activity of 6.25 μg/mL and 1.25 μg/mL respectively, and can be considered as a good start point for the discovery of new lead compounds in the field of multi-drug resistant tuberculosis.
