    Novobiocin Sodium

    $43.37 - $154.82

    Novobiocin Sodium is an aminocoumarin antibiotic that prevents cell division.  It targets Gram-positive organisms, and is commonly used for antimicrobial susceptibility testing.  It is also used in plant tissue culture to control contamination.

    Novobiocin Sodium is freely soluble in water.

    Mechanism of Action Aminocoumarin antibiotics target DNA gyrase, an enzyme which relieves strain as DNA unwinds during replication and transcription.
    Spectrum Novobiocin Sodium targets primarily Gram-positive organisms and is commonly used to differentiate between coagulase negative (all but S. aureus and a few others) Staphylococcus species. S. saprophyticus is resistant to Novobiocin.
    Microbiology Applications Novobiocin Sodium is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against Gram-positive microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options.  Representative MIC values include:
    • Staphylococcus aureus 0.25 µg/mL
    • Staphylococcus saprophyticus 2 µg/mL

    Plant Biology Applications Novobiocin can be used in combination with gentamicin to prevent and cure Bacillus contamination in plant tissue culture. Benjama et al. demonstrated the potency of this combination in contaminated date palm tissue which led to routine use in plant science applications.
    Cancer Research Applications Novobiocin, a coumermycin antibiotic, is known to enhance anticancer drug sensitivity of cancer cells in vitro and in vivo, the mechanism of which remains undetermined.  Novobiocin was a inhibitor for Breast Cancer Resistance Protein (BCRP) resulting in competitive inhibition of BCRP-mediated topotecan transport suggesting that Novobiocin can overcome BCRP-mediated resistance (Shiozawa, 2004).
