A new series of isonicotinoyl hydrazone derivatives (3a-3o) have been synthesized, characterized and evaluated for in vitro antimycobacterial activity against M. tuberculosis H37Rv and two clinical isolates using tetrazolium microplate assay (TEMA). Some of these compounds showed moderate to good antimycobacterial activity at micro molar concentrations. Among them, 3k and 3m were the most potent analogues with an inhibition concentration at 0.59 and 0.65 mu M, respectively, against M. tuberculosis H37Rv compared to parent drug, isoniazid (0.57 mu M). Additionally, all the synthesized compounds were subjected to in vitro anticancer activity against human colorectal cancer cell lines (HCT 116). Compounds 3b and 3l displayed antiproliferative activity at inhibitory concentration 3.1 and 0.29 mu M, respectively, when compared to standard, 5-fluorouracil (5 mu M). These results can be considered as an important start point for the rational design of new leads for antitubercular and anticancer drug discovery.

Octahedral cobalt(II) complexes of isonicotinoylhydrazones. which were obtained from the primary antituberculous agent isoniazid, have been synthesised and characterised. Their antimycobacterial in vitro activity has been evaluated against Mycobacterium tuberculosis H37Rv: they exhibit MIC values ranging from < 0.1 to 0.19 g/mL, showing them to be generally more active than previously reported analogous Cu(II) and NI(II) complexes, (C) 2001 Elsevier Science Ltd.

A series of 22 (E)-N'-(monosubstituted-benzylidene)isonicotinohydrazide derivatives have been synthesized and evaluated for their in vitro antibacterial activity against Mycobacterium tuberculosis H37RV using Alamar Blue susceptibility test and the activity expressed as the minimum inhibitory concentration (MIC) in mu g/mL. Compounds 2f, 2g, 2j, 2k and 2q exhibited a significant activity (0.31-0.62 mu g/mL) when compared with first line drugs such as isoniazid (INH) and rifampicin (RIP) and could be a good starting point to develop new lead compounds in the fight against multi-drug resistant tuberculosis.
