    Colistin Sodium Methanesulfonate

    $134.00 - $1,000.00

    Colistin Sodium Methanesulfonate is considered an inactive prodrug of Colistin, which means it is inactive until converted into Colistin by cellular enzymes. It is prepared by the reaction of Colistin with formaldehyde, followed by sodium bisulfate. It is also less potent and less toxic than Colistin Sulfate and is effective against Gram-negative bacteria. Colistin works by targeting the bacterial cell membrane, leading to reduced permeability and cell death.  The product has been explored with renewed interest as a possible anti-tuberculosis effects.  

    We also offer:

    • Colistin Sulfate, USP (C083)
    • Colistin Sulfate, EP (C039)

    This product is considered a dangerous good. Quantities above 1 g may be subject to additional shipping fees. Please contact us for details.

    Mechanism of Action THe mechamism of action of Colistin Methanesulfonate has not been fully expllored, and has only been described from a histological and genomics perspective.  Researchers used a GCxGC-TOFMS metabolomics approach and found that the prdouct acts by disrupting the cell wall of Mycobacteria.  
    Spectrum Colistin primarily targets and disrupts the cell wall of Gram negative bacteria and Mycobacteria.
    Microbiology Applications Colistin is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against gram negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options for infected patients. Representative MIC values include:
    • Shigella spp. 64 µg/mL -128 µg/mL
    • Haemophilus influenzae 0.4 µg/mL – 0.8 µg/mL
