    Mezlocillin Sodium

    ৳36,424.71 - ৳103,764.51

    Mezlocillin Sodium is broad-spectrum, semisynthetic, β-lactam antibiotic and ureido penicillin derived from ampicillin.  It is sparingly soluble in aqueous solution. 

    Mechanism of Action β-lactams 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 β-lactams is commonly due to cells containing plasmid-encoded β-lactamases, however, Mezlocillin is resistant to a number of β-lactamases.
    Spectrum Mezlocillin is a broad-spectrum antibiotic targeting a wide variety of Gram-positive and Gram-negative bacteria.
    Microbiology Applications Mezlocillin 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. Representative MIC values include:
    • Helicobacter pylori 0.125 µg/mL – 0.25 µg/mL

    Eukaryotic Cell Culture Applications Mezlocillin did not cause any cytotoxicity in cell cultures of mouse sarcoma L-1, human lung cancer E-14, or human malignant melanoma MEW (Roszkowski et al, 1984).
    Molecular Formula C21H24N5NaO8S2
