ABSTRACT
As part of ongoing studies in developing new antimicrobials, a novel series of 4-acetamido-N-(substituted 1, 3-benzothiazol-2-yl) benzenesulphonamide and N-(substituted 1, 3-benzothiazol-2-yl)-4-(substituted aryl diazenyl) benzenesulphonamide were synthesized in order to determine their antibacterial and antifungal activity. The synthesized compounds were tested in vitro against two Gram-positive bacteria like Staphylococcus aureus, Bacillus subtilis; two Gram-negative bacteria like Escherichia coli, Pseudomonas aeruginosaand one fungal strain Candida albicans in comparison with standard drugs. Microbiological results showed that the synthesized compounds possessed a broad spectrum of antibacterial and antifungal activity against the tested microorganisms. The compounds with a 6-chloro (SK5b), 7-chloro-6-fluoro(SK5d) and 6-nitro (SK5e) on 2-amino benzothiazole ring possessing azo linkage showed better antimicrobial activity; almost similar or less to that of standard drugs thus they could be promising candidates for novel drugs. The novel heterocyclic derivatives were characterized by Physical characterization (Melting point, TLC) and different Spectroscopy techniques (IR, 1H NMR and Mass spectroscopy).
