An improved synthesis of biotinol-5′-AMP, an acyl-AMP mimic of the natural reaction intermediate of biotin protein ligase (BPL), is reported. This compound was shown to be a pan inhibitor of BPLs from a series of clinically important bacteria, particularly Staphylococcus aureus and Mycobacterium tuberculosis, and kinetic analysis revealed it to be competitive against the substrate biotin. Biotinol-5′-AMP also exhibits antibacterial activity against a panel of clinical isolates of S. aureus and M. tuberculosis with MIC values of 1-8 and 0.5-2.5 μg/mL, respectively, while being devoid of cytotoxicity to human HepG2 cells.
