Two series of sulfonamides were synthesized from 4-hydrazinylben-zenesulfonamide as the key starting material. 1,3,5-Triarylpyrazoline sulfonamides (2a-i) were obtained by cyclocondensation of various chalcones in 53-64 % yields, while 4-thiazolidinone derivatives (4a-e) were synthesized by cyclocondensation between mercaptoacetic acid and different phenylhydrazones in 43-62 % yields. The synthesized compounds were characterized based on FTIR, 1H-NMR, 13C-NMR and HRMS data. The sulfonamides were evaluated for their in vitro antimicrobial activities against four bacterial strains (E. coli, P. aeruginosa, B. subtillis and S aureus), two filamentous fungal strains (A. Niger and F. oxysporum) and two yeast strains (C. albicans and S. cerevisiae). Seven pyrazolines, 2a-c and 2e-h, exhibited significant inhibition of different microbial strains. Among them, compound 2b displayed good antifungal activity against A. Niger (MIC value at 12.5 μg mL-1) over the reference drug.
