The synthesis and biological activity of N-heteroaryl substituted benzene sulphonamides (3a–h) were successful. Simple condensation reaction of benzene sulphonyl chloride (1) with substituted heteroaromatic compounds (2a–h) under dry pyridine and acetone gave the target molecules (3a–h) in good to excellent yield. The compounds were characterized using FTIR, 1HNMR, and 13CNMR. The compounds were screened for antibacterial activity against E. coli, Salmonella typhi, P. aeruginosa, B. cereus, K. pneumonia, and Sarcina  lutea and antifungal activity against C. albicans and A. niger. The results of the antimicrobial activity showed improved biological activity against some tested organisms.
