Tomopenem

Synonym(s): CS-023  |  RO4908463  |  R-115685

Class: Beta-lactam (carbapenem)

Spectrum of activity:	Gram-positive  &  Gram-negative
Details of activity:	Binds to bacterial penicillin-binding proteins (PBP) and interferes with bacterial cell wall integrity and synthesis. Carbapenems bind to all PBPs, with PBP2 and PBP4 as the highest-affinity targets. Carbapenems have a very broad spectrum incl. non-fermenters and are not hydrolysed by most beta-lactamases with exception of carbapenemases.
