A neuropeptide with diverse biological activities
Doripenem-d4 is intended for use as an internal standard for the quantification of doripenem by GC- or LC-MS. Doripenem is a broad-spectrum antibiotic in the β-lactam subclass known as carbapenems.1,2 It is active against Gram-negative and Gram-positive bacteria, including S. aureus, S. pneumoniae, E. coli, and K. pneumoniae (MICs = 0.03-0.06, 0.016-0.06, <0.015-0.3, and 0.03-0.06 µg/ml, respectively).1,2,3,4 Doripenem reduces the number of viable bacteria in mouse lung in a model of chronic P. aeruginosa respiratory tract infection when administered at a dose of 100 mg/kg per day.5 It inhibits bacterial cell wall synthesis by forming stable acyl enzymes with penicillin-binding proteins, thereby inactivating them.2 Formulations containing doripenem have been used in the treatment of bacterial infections.
