Vaborbactam

Research use only, not for human use.

A serine β-lactamase inhibitor that notably restores the activity of carbapenems against KPC-producing strains.

A serine β-lactamase inhibitor that notably restores the activity of carbapenems against KPC-producing strains; restores meropenem activity for 72.7 to 98.1% of CPE isolates at ≤2 ug/ml; showes no antibacterial activity alone (MICs, >64 ug/ml).Bacterial Infection Approved.

Vaborbactam is a broad spectrum of inhibition of β-lactamases, with particularly potent activity against KPC, CTX-M, SHV, and CMY enzymes. Vaborbactam restores SM 7338 activity for 72.7 to 98.1% of CPE isolates at ≤2 μg/mL, and maximum potentiation is achieved with fixed concentrations of ≥8 μg/mL of the inhibitor (≥96.5% of isolates are inhibited at ≤2 μg/mL of SM 7338-vaborbactam). SM 7338-vaborbactam with a fixed concentration of 8 μg/mL of the inhibitor (MIC50, ≤0.06 μg/mL for all organisms) inhibits 93.7% of the CPE isolates displaying elevated SM 7338 MICs at ≤1 μg/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.
