GtoPdb Ligand ID: 10926

Synonyms: BRL-17421 | BRL17421 | Negaban®
Approved drug
temocillin is an approved drug (UK (2005))
Compound class: Synthetic organic
Comment: Temocillin is a penicillinase (β-lactamase)-resistant penicillin that is active against Gram-negative bacteria. It is primarily used to treat infections caused by multiple drug-resistant strains of Enterobacteriaceae, especially those that produce extended-spectrum β-lactamase or AmpC β-lactamase. Temocillin is not effective against Acinetobacter species or Pseudomonas aeruginosa.

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.

Summary of Clinical Use Click here for help
Temocillin has marketing authorisation in the UK where it is is indicated for the treatment of septicaemia, urinary tract infection and lower respiratory tract infection where susceptible Gram-negative bacilli are suspected or confirmed. The EMA granted orphan designation for the treatment of Burkholderia cepacia lung infection in cystic fibrosis patients in 2004.
