From: Characterization of GQA as a novel β-lactamase inhibitor of CTX-M-15 and KPC-2 enzymes
Representation of the half maximal inhibitory concentration (IC50) values for GQAs, clavulanic acid, and tazobactam against the CTX-M-15 (A) and KPC-2 (B) enzymes are shown as percent residual activity of the test enzyme against log concentrations of the compounds and nitrocefin was used as a substrate. IC50 calculated by GraphPad prism software
