    Moxifloxacin Hydrochloride

    $116.96 - $467.86

    Moxifloxacin Hydrochloride is a broad-spectrum fourth-generation fluoroquinolone antibiotic that can be used against the bacteria causing respiratory infections. Moxifloxacin Hydrochloride is sparingly soluble in aqueous solution.

    Mechanism of ActionFluoroquinolone antibiotics target bacterial DNA gyrase, an enzyme which reduces DNA strain during replication. Because DNA gyrase is required during DNA replication, subsequent DNA synthesis and ultimately cell division is inhibited.

    Moxifloxacin is bactericidal against wild-type and first-step gyrase- and topoisomerase IV-resistant mutants.  The 8-methoxy group on moxifloxacin appeared to significantly lower the propensity for quinolone resistance development (Dalhoff, 2011).
    SpectrumMoxifloxacin is a broad-spectrum antibiotic commonly used Gram-positive and Gram-negative bacteria. It is effective against bacteria that case respiratory infections including S. pneumonia. It is also effective for obligate anaerobes including Bacteriodes, Fusobacterium, Bilophila, and Clostridium.

    Microbiology ApplicationsMoxifloxacin Hydrochloride is commonly used in clinical in vitromicrobiological 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:
    • Haemophilus influenzae 0.008 µg/mL – 0.25 µg/mL
    • Streptococcus pneumoniae 0.03 µg/mL - 8 µg/mL

    Eukaryotic Cell Culture Applications

    A cell culture model to investigate the safety of moxifloxacin for intracameral application was investigated in cultured human corneas to review endothelial toxicity.  Moxifloxacin at 10-750 ug/ml was evaluated in endothelial cells, primary human trabecular meshwork cells (TMC), and primary human retinal pigment epithelial (RPE) cells.  Concentrations up to 150 ug/ml had no influence on endothelial cells, TMC, or RPE when exposed for up to 24 hours (MIC90 is 0.25-2.5 ug/ml).(Kernt et al, 2009).
