Application
Efflux pump research
4-Bromophenylboronic acid has been reported to act as an inhibitor of Staphylococcus aureus NorA efflux pump.1) The compound was found to potentiate ciprofloxacin activity by a 4-fold increase at concentrations ranging at 2-4 μg/ml against S. aureus 1199B, which overexpresses NorA.1)

Application
AmpC β-lactamase inhibitor
The primary resistance mechanism of microbes to β-lactam antibiotics is hydrolysis of the antibiotics by β-lactamase.1) 4-Bromophenylboronic acid is one of boronic acid compounds having β-lactamase (AmpC) inhibition activity (Ki = 3.6 ± 0.9 μM).2)
