Vaborbactam is a cyclic boronic acid pharmacophore β-lactamase inhibitor.
Vaborbactam is a broad spectrum of inhibition of β-lactamases, with particularly potent activity against KPC, CTX-M, SHV, and CMY enzymes. Vaborbactam restores meropenem activity for 72.7 to 98.1% of CPE isolates at ≤2 ug/mL, and maximum potentiation is achieved with fixed concentrations of ≥8 ug/mL of the inhibitor (≥96.5% of isolates are inhibited at ≤2 ug/mL of meropenem-vaborbactam). Meropenem-vaborbactam with a fixed concentration of 8 ug/mL of the inhibitor (MIC50, ≤0.06 ug/mL for all organisms) inhibits 93.7% of the CPE isolates displaying elevated meropenem MICs at ≤1 ug/mL. By forming a reversible dative bond with the blactamase, vaborbactam acts as a competitive inhibitor and is not hydrolyzed by the b-lactamase.
Vaborbactam is well tolerated and has a half-life of 1.23 h, and steadystate volume of distribution of 21.0 L in subjects.
