We report the synthesis and evaluation of 5-halogenated-1,2,3-Triazoles as inhibitors of biotin protein ligase from Staphylococcus aureus. The halogenated compounds exhibit significantly improved antibacterial activity over their nonhalogenated counterparts. Importantly, the 5-fluoro-1,2,3-Triazole compound 4c displays antibacterial activity against S. aureus ATCC49775 with a minimum inhibitory concentration (MIC) of 8 μg/mL.
