Synthesis, Characterization and Antibacterial Activity of 2-Phenylsulphonamide Derivatives of Some Amino Acids

Full Text PDF


The 2-phenylsulphonamide derivatives of amino acids were synthesis by simple substitution of benzenesulphonylchloride (6) with amino acids (1-5) containing pharmacological active functionalities. Structures of the synthesised compounds (7a-7e) were characterised using FT-IR, NMR (1H, 13C) and elemental analysis. The anti bacterial activities of the synthesised compounds were evaluated against gram positive bacteria: Staph and Streptococcus, gram negative bacteria: E-coli, Klebsiella, Proteus, and pseudomonas using 200 µl of 10 mg/ml and minimum inhibitory concentration (MIC) were also determined. The compounds exhibited effective anti bacterial properties though some are not more active than the standard drug ciprofloxacin.
