Summary: | A novel series of 2-(5-(3-(4-fluorophenyl)-1-phenyl-1H-pyrazol-4-yl)-3-(aryl)-4,5-dihydro-1H-pyrazol-1-yl)thiazol-4(5H)-ones (4a–q) were prepared and screened for in vitro antimicrobial activity. [Display omitted]
► Describe facile synthesis of fluorine containing pyrazole based thiazole compounds. ► Compounds were screened for their in vitro antimicrobial activity. ► Compounds were characterized adequately by various spectral data and CHN analysis. ► Newly synthesized compounds exhibited potential antimicrobial activity.
A series of compounds 2-(5-(3-(4-fluorophenyl)-1-phenyl-1H-pyrazol-4-yl)-3-(aryl)-4,5-dihydro-1H-pyrazol-1-yl)thiazol-4(5H)-ones (4a–q) were synthesized and structures of these compounds were elucidated by spectral (IR, 1H NMR, 13C NMR, mass spectra) analysis. Synthesized compounds were screened for in vitro antibacterial activity against the representative panel of Gram-positive (Staphylococcus aureus, Streptococcus pyogenes) and Gram-negative (Escherichia coli, Pseudomonas aeruginosa) bacteria. These compounds were also tested for their inhibitory action against strains of fungi (Candida albicans, Aspergillus niger, Aspergillus clavatus). The synthesized compounds showed potent inhibitory action against the test organisms. |
