Background:

Cefprozil-d4is intended for use as an internal standard for the quantification of cefprozil by GC- or LC-MS. Cefprozil is an orally bioavailable, second generation, broad-spectrum cephalosporin antibiotic that inhibits the growth of both Gram-positive and Gram-negative bacteria.1,2It inhibits the growth ofE. coli,E. faecalis,E. faecium,N. gonorrhoeae,N. meningitidis,P. mirabilis,S. aureus,S. pyogenes, andS. pneumoniaestrains (MICs = 0.013-25 μg/ml) and clinical isolates of penicillin-susceptible, -intermediate, and -resistantS. pneumoniaeand methicillin-sensitiveS. aureus(MIC90s = 0.12-16 μg/ml).In vivo, cefprozil protects mice challenged withE. coli,S. aureus,S. pyogenes, andP. mirabilisstrains with protective doses (PD50s) ranging from 0.07 to 1.3 mg/kg.1Cefprozil binds to penicillin-binding proteins (PBPs), which disrupts their ability to cross-link peptidoglycan and leads to weakened bacterial cell walls.3Formulations containing cefprozil have been used in the treatment of respiratory tract, skin, and other bacterial infections.
