GtoPdb Ligand ID: 13082

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.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.

Bioactivity Comments
Ledaborbactam demonstrates inhibitory activity against serine β-lactamases from Ambler A, C, and D classes, including the carbapenemases KPC-2 (IC50 = 0.08 μM) and OXA-48 (IC50 = 0.32 μM) [1]. It restores the antibacterial activity of ceftibuten against strains of Enterobacterales expressing clinically important extended spectrum β-lactamases (ESBLs) and serine carbapenemases [1-2].
