Series of 1-[(2E)-3-phenylprop-2-enoyl]-1H-benzimidazole derivatives were synthesized and characterized by spectral methods. Among 21 derivatives, single crystals of 3a and 3l were grown and their structural parameters were evaluated. Newly synthesized compounds were screened for anti-tubercular activity and the MIC was determined against Mycobacterium tuberculosis H37Rv by Microplate Alamar Blue Assay (MABA) method. Majority of the compounds exhibited a promising inhibition of M. tuberculosis and the molecules functionalized with electron-donating groups at C-2 carbon of benzimidazole moiety were found to be more active in inhibiting M. tuberculosis. Further, more promising compounds viz., 3b, 3i and 3l were tested for their cytotoxic activity. Compound 3l was found to display excellent activity (IC50 < 10 mu g mL(-1)) with 100% cell lysis at 30 mu g mL(-1) concentration against A549 (Human lung carcinoma) and 8E5 (Human; Acute Lymphoblastic Leukemia) cell lines.

exerted superior or comparable activity to all the reference drugs. In the celldivision inhibitory activity, all the compounds showed the same trend as their in vitro antibacterial activity, exhibiting better activity against S. aureus ATCC25923 than the other strains. Additionally, compounds 3, 6, 7 and 8 displayed potent celldivision inhibitory activity with an MIC value of below 1 μg/mL, over 256-fold
