Several novel thiazolylpyrazoline derivatives were synthesized by reacting substituted 3,5-diaryl-1-thiocarbamoyl-2-pyrazolines with phenacylbromides. The structures of the synthesized compounds were confirmed by IR, H-1 NMR, C-13 NMR, and MS spectral data. Their antimicrobial activities against Staphylococcus Atreus (ATCC-25923), Enterococcus faecalis (ATCC-29212), Enterococcus faecalis (ATCC-51922), Listeria monocytogenes (ATCC-1911), Klebsiella pneumoniae (ATCC-700603), Pseudomonas aeruginosa (ATCC-27853), Escherichia coli (ATCC-35218), Escherichia coli (ATCC-25922), Candida albicans (ATCC-90028), Candida glabrata (ATCC-90030), Candida krusei (ATCC-6258), and Candida parapsilosis (ATCC-22019) were investigated. The compounds were also studied for their cytotoxic effects using a MIT assay. Compound 7c showed the highest antimicrobial activity, possessing the same potential as chloramphenicol against K. pneumonia, P. aeruginosa, and E. coli (ATCC-25923).
