Synonyms: QPX7728
PDB Ligand
Compound class: Synthetic organic
Comment: Xeruborbactam is a bicyclic boronate β-lactamase inhibitor (BLI) with a broad-spectrum of activity against both serine and metallo-β-lactamases [1]. Xeruborbactam is under clinical evaluation and was developed as a continuation of the program that discovered vaborbactam, with the aim of expanding the spectrum of activity to allow treatment of infections caused by a wider range of pathogens.

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.

Summary of Clinical Use Click here for help
An intravenously administered combination of xeruborbactam and QPX2014 (an undisclosed β-lactam antibacterial), has completed two Phase 1 trials (NCT04380207 and NCT05072444). This drug combination is being developed by Qpex Biopharma (registered trademark OMNIvance®) as a treatment for serious infections caused by drug-resistant strains of Acinetobacter, Pseudomonas and Enterobacterales.
QPX7831, an orally bioavailable xeruborbactam prodrug, is also under clinical evaluation.
