Temocillin was marketed by Beecham Pharmaceuticals in the UK in the 1980s but achieved little commercial success and was withdrawn, though it remained available via the manufacturer’s medical department. Presently licensed to Eumedica, temocillin is being re-launched in the UK and Belgium for treating UTI, sepsis, and respiratory infections by ESBL (Extended-spectrum beta-lactamases) and AmpC-producing Enterobacteriaceae. It acts by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls. It irreversibly binds to the active site of specific transpeptidases and carboxypeptidases known as Penicillin Binding Proteins (PBP), preventing peptidoglycan production.

Temocillin is a carboxypenicillin; a methoxy group in the 6-alpha position should confer to the molecule greater stability to beta-lactamases. 236 strains isolated from clinical specimens were tested. Enterobacteriaceae were very susceptible, MICs being generally less than or equal to 8 micrograms/ml and always less than 32 micrograms/ml. The activity of the drug was equal against the beta-lactamases producing strains
