Concentration-response curves of compound 1 against S. aureus SA1199 (red circles) and methicillin-resistant S. aureus AH1263 (blue squares). The minimum inhibitory concentration (MIC) of compound 1 was ≤ 8.7 μM against both S. aureus strains. The MIC of the positive control, berberine, was 223 μM against both S. aureus strains.
