A series of sulfonamides having biologically active acrylamides moieties (2, 3, 5), penta-2,4-dienamide (4), chromene-2-carboxamide (6), acetamide derivatives (7, 8) and pyridone derivative (9) were prepared. The structure of the synthesized compounds was verified by elemental analyses, IR, 1H NMR and 13C NMR spectra. In addition, the structure compound 9 was confirmed through X-ray crystallography. The antibacterial activities of all the synthesized compounds were evaluated against a panel of multi-drug resistant (MDR) Gram-negative strains of Escherichia coli, Enterobactera erogenes, Klebsie-llapneumoniae and Pseudomonas aeruginosa whilst their cytotoxic effects were tested against the leukemia CCRF-CEM and its adriamycin resistant subline CEM/ADR5000 cell lines. Compounds 1-5, 7 and 8 displayed or weak activities on at least one of the ten tested bacterial strains. The best MIC value of 64 μg/mL was obtained with 3 against E. aerogenes ATCC 13048. None of the compounds displayed significant cytotoxic effect against the two studied leukemia cell line. Nevertheless, the activity of compounds 4, 5, 8 and 9 were better than that of doxorubicin towards the resistant CEM/ADR5000 cell line.
