GtoPdb Ligand ID: 13114

Synonyms: XNW4107
Compound class: Synthetic organic
Comment: Funobactam (XNW4107) is a novel serine β-lactamase inhibitor, belonging to the diazabicyclooctane (DBO) class [1]. It enhances the activity of carbapenem antibacterials against carbapenem-resistant strains of Acinetobacter baumannii and Klebsiella pneumoniae [1]. Funobactam is in clinical development in combination with imipenem + cilastatin for the treatment of complicated urinary tract infections (cUTIs) and hospital acquired/ventilator-associated bacterial pneumonia (HABP/VABP).

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.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the CDK toolkit. All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

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
Funobactam has no intrinsic antibacterial activity but exhibits in vitro activity against Ambler class A, C, and D β-lactamases, including those produced by Acinetobacter baumannii [1]. The combination of funobactamIn with imipenem was found to have potent in vitro activity against carbapenem-resistant Gram-negative bacteria [1].
