A novel series 2-(1H-benzimidazol-2-ylsulfanyl) -N-(4-oxo-2-phenyl-thiazolidin-3yl) Various aldehydes and 2-acetamides have been used to synthesise -acetamide 5a–j (5-phenyl-[1,3,4]-oxadiazol-2-ylmethylsulfanyl) - 1H-benzimidazole 6a–j derived from a variety of benzoic acids. These compounds were tested in vitro for antibacterial activity against Gram positive bacteria Staphylococcus aureus and Enterococcus faecalis, Gram negative bacteria Klebsiella pneumoniae and Escherichia coli, and antifungal activity against Aspergillus fumigatus and Candida albicans. The in vitro cytotoxic properties of brine shrimp were investigated using a bioassay. Compounds 5b, 5d, 5g, 5i, 6b, 6e, 6f, and 6i demonstrated excellent activity against a panel of microorganisms, according to the results. 5b, 5g, 5i, 6b, 6f, 6h, and 6i were found to have good cytotoxic activities. Elements, IR, 1H-NMR, 13C-NMR, and MS were used to characterise all of the newly synthesised compounds. Keywords: Antibacterial, Antifungal, 4-Thiazolidinone,1,3,4-Oxadiazole, Cytotoxicity. |
