A series of novel substituted hydrazinecarbothioamides was synthesized and evaluated for anti-TB activity. Three most active compounds viz. 1, 6 and 12 were found to exhibit minimum inhibitory concentration (MIC) of 0.4 microg/mL, whereas four compounds viz. 3, 5, 10 and 11 showed comparatively lesser activity with MIC value of 0.8 microg/mL against Mycobacterium tuberculosis strain. A highly significant QSAR equation explaining 81.8% variance is described.
