A series of structurally novel, (E)-N'-(4-aryloxybenzylidene)-1H-benzimidazole-2-carbohydrazide derivatives
were synthesized by molecular hybridization technique. All these compounds were evaluated against Mycobacterium
tuberculosis H37Rv strains using Resazurin Microtiter assay (REMA) method. These compounds showed good
antituberculosis activity with minimum inhibitory concentration (MIC) value of the range of 1.5-25 µg/mL.
Keywords: Anti-tubercular, benzimidazole, carbohydrazide esters, triclosan, molecular hybridization.
