Synonyms: VNRX-5236
Compound class:
Synthetic organic
Comment: Ledaborbactam (VNRX-5236) is a novel broad-spectrum boronic acid β-lactamase inhibitor (BLI). It is a reversible covalent inhibitor of serine β-lactamases (classes A, C, D) [1].
Ledaborbactam etzadroxil (VNRX-7145, PubChem CID 138455030), an orally bioavailable prodrug of ledaborbactam [3], is being developed in combination with ceftibuten for the treatment of infections caused by drug-resistant Enterobacterales. |
