The research aimed to synthesize and evaluate the antifungal and cytotoxic properties of 14 different 2-[(1-methyl-1H-tetrazole-5-yl)thio]-1-(phenyl)ethanone derivatives. The study was motivated by the increasing incidence of fungal infections, particularly those caused by Candida species, and the need for new antifungal agents due to growing drug resistance. The compounds were synthesized using a one-pot method involving 1-methyl-1H-tetrazole-5-thiol and various phenylacetyl bromide derivatives. The structures were confirmed through IR, 1H-NMR, 13C-NMR, FAB-MS, and elemental analysis. The synthesized compounds were tested for their anticandidal activity against eight Candida species using the microbroth dilution method and for cytotoxicity against NIH/3T3 cells using the MTT assay. The results showed that several compounds exhibited potent antifungal activity, with some displaying better efficiency than the reference drug ketoconazole, particularly against C. albicans strains. Compounds 1, 12, and 13 were highlighted for their selective anticandidal effect and low cytotoxicity, suggesting that chloro substitution on the benzene ring enhances antifungal activity. The study concluded that these tetrazole derivatives could serve as potential candidates for the development of new antifungal agents.
