Description: Zidebactam, also known as WCK-5107, is a Beta lactamase inhibitor. Zidebactam is a novel Inhibitor of PBP2 Showing Potent "β-Lactam Enhancer" Activity against Pseudomonas aeruginosa, Including Multidrug-Resistant Metallo-β-Lactamase-Producing High-Risk Clones. Zidebactam demonstrated specific high-affinity binding to PBP2 of A. baumannii (0.01 μg/ml for both of the compounds). The MIC of zidebactam was >1,024 μg/ml for wild-type and multidrug-resistant Acinetobacter strains. Zidebactam is a PBP2 inhibitor that show a potent β-lactam enhancer effect against A. baumannii, including a multidrug-resistant OXA-23-producing ST2 international clone.
