Doripenem

Synonym(s): S-4661

Class: Beta-lactam

Agent Type: Semisynthetic; Small molecule; Direct acting;
Spectrum of activity: Gram-positive & Gram-negative
Mechanism of action: Cell wall synthesis inhibitor. 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 including non-fermenters and are not hydrolysed by most beta-lactamases with exception of carbapenemases; PBP inhibitor
Description: Semisynthetic, derived from thienamycin. Similar to meropenem
Institute where first reported: Shionogi Inc
Year first mentioned: 2003
Highest development stage: Approved by FDA in 2007
Development status: Active
Reason dropped: In treating patients with pneumoniae, doripenem showed increased risk of death and lower clinical cure rates compared to imipenem and cilastatin for injection
