Description

Cefpirome sulfate solubilized is a mixture of Cefpirome sulfate with anhydrous sodium carbonate and is used to stabilize pH.  Cefpirome sulfate is a semisynthetic, broad-spectrum, fourth generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis.  Cefpirome sulfate is soluble in water at 10 mg/mL.

TOKU-E offers two forms of Cefpirome: 

    CAS Number

    98753-19-6 (Cefpirome Sulfate)

    Molecular Formula

    C22H22N6O5S2·H2SO4 (Cefpirome Sulfate)

    Molecular Weight

    612.66 (Cefpirome Sulfate)

    Mechanism of Action

    Like β-lactams, cephalosporins interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to cephalosporins is commonly due to cells containing plasmid encoded β-lactamases.

    The relative lack of cross-resistance between Cefpirome and the third generation cephalosporins suggests a slightly different mechanism of action of Cefpirome in comparison to the other cephalosporins.

    Due to its compact dipolar structure, Cefpirome can penetrate Gram-negative bacteria more quickly than the other agents (Nikaido et al, 1990).

    Storage Conditions

    -20°C

    Tariff Code

    2941.90.3000

    Spectrum

    Cefpirome is a broad spectrum antibiotic targeting a wide variety of Gram-positive and Gram-negative bacteria. Many Bacteroides, Enterococci, and Haemophilus species have developed resistance to cefpirome.

Applications

    Cancer Applications

    Cefpirome was found to be more effective than ceftazidime, aztreonam, timentin, and piperacillin against nosocomially important isolates from cancer patients during in vitro examination of 253 bacterial isolates (Rolston et al, 1986).

    Microbiology Applications

    Cefpirome sulfate solubilized is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against Gram-positive and Gram-negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options for infected patients. Representative MIC values include:

    • Campylobacter jejuni 0.5µg/mL – 8 µg/mL
    • Klebsiella pneumoniae 0.032 µg/mL – 0.125 µg/mL
