WCK-4234 is a potent β-lactamase inhibitor. WCK-4234 inhibits class A, C, and D β-lactamases activity. WCK-4234 lacks direct antibacterial activity. WCK-4234 potentiates imipenem and meropenem against Enterobacteriaceae with OXA-48/OXA-181 or KPC enzymes, or with combinations of impermeability and AmpC or ESBL activity. WCK-4234 distinctively overcomes resistance mediated by OXA-type carbapenemases[1][2].
