IC50: 12.5 μM (PqsR in E. coli), 23.6 μM (PqsR in P. aeruginosa), 87.2 μM (virulence factor pyocyanin)[1]
4-(tert-Butyl)-benzdroxamic Acid is a PqsR antagonist with IC50s of 12.5 μM and 23.6 μM for E. coli and P. aeruginosa, respectively. 4-(tert-Butyl)-benzdroxamic Acid reduces the production of the virulence factor pyocyanin in P. aeruginosa with an IC50 of 87.2 μM[1].
