Synthesis and studies on some new fluorine containing triazolothiadiazines as possible antibacterial, antifungal and anticancer agents

Synthesis of a series of 7-arylidene-6-(2,4-dichlorophenyl)-3-aryloxymethyl/anilinomethyl-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazines (3) by the condensation of 3-aryl-1-(2,4-dichloro-5-fluorophenyl)-2-bromo-propen-1-one (1) and 4-amino-5-mercapto-3-aryloxymethyl/anilinomethyl-1,2,4-triazoles (2) is described. The newly synthesized compounds were characterized by elemental analysis IR, 1H NMR and mass spectral data. These compounds were tested for their antimicrobial activities against Escherichia coli, Staphylococcus aureus (Smith), Psuedomonas aeruginosa (Gessard), Bacillus subtilis and Candida albicans. Some of the newly synthesized compounds were also screened for their anticancer activity. Among them compounds 3m, 3o, 3q showed in vitro anticancer activity.

The newly synthesized compounds were well characterized by analytical and spectral studies. The in vitro antibacterial, antifungal and anticancer studies on these compounds were also described.Figure optionsDownload as PowerPoint slide
