Abstract

Inhibitors of Staphylococcus aureus biotin protein ligase (SaBPL) are generated by replacing the acyl phosphate group of biotinyl-5′-AMP with either a 1,2,3-triazole (see 5/10a/10b) or a 1,2,4-oxadiazole (see 7) bioisostere. Importantly, the inhibitors are inactive against the human BPL. The nature of the 5-substituent in the component benzoxazolone of the optimum 1,2,3-triazole series is critical to activity, where this group binds in the ATP binding pocket of the enzyme.
