Description

Cefamandole sodium salt is a second generation cephalosporin antibiotic.

TOKU-E offers two forms of cefamandole: cefamandole nafate (C078), and cefamandole sodium salt (C079). In aqueous solution, cefamandole nafate is freely soluble and sparingly soluble in methanol. Cefamandole sodium is freely soluble in an aqueous solution.

    CAS Number

    Molecular Formula

    C18H17N6NaO5S2

    Molecular Weight

    484.48

    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.

    Storage Conditions

    -20°C

    Spectrum

    Cefamandole is a broad spectrum cephalosporin targeting a wide variety of gram positive and gram negative bacteria.

Applications

    Microbiology Applications

    Cefamandole sodium salt 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:

    • Escherichia coli 0.08 µg/mL – 100 µg/mL
    • Klebsiella pneumoniae 0.8 µg/mL – 12.5 µg/mL

    Media Supplements

    Cefamandole can be used as a selective agent in several types of isolation media:

    Legionella CYE Agar - Legionella BMPA-α Selective Supplement
