    Moxifloxacin Hydrochloride

    $127.00 - $505.00

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

    Mechanism of Action

    Fluoroquinolone 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).

    The anticancer properties is lined to anti-human Topoisomerase II activity.  Many studies suggest that various different cancer tissues have own unique microbiota and that bacteria associated with theise tumors could in fact contribute to DNA damage and the progression of hte umors including angiogeneiss.

    Some Moxifloxacin drivatives have activity agaisnt various cancer cells in vitro.  An example is some Moxifloxacin-isatin hybrids which showed anticancer activity agaisnt liver cancer cells HepG2, breast cancer cells MCF-7, MCF-7/DOX, prostate cancer cells DU-145 and MDR DU-145.  

    All 7, novel moxifloxacin-fatty acid amides tested showed cytostatic (or cytotoxic) activity agasint colorectal and prostate cancer cell lines but were not toxic agaisnt normal keratinocytes.  (Chrzanowska et al, 2023).

    Spectrum Moxifloxacin 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 Applications Moxifloxacin Hydrochloride 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:
    • 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 µg/ml was evaluated in endothelial cells, primary human trabecular meshwork cells (TMC), and primary human retinal pigment epithelial (RPE) cells.  Concentrations up to 150 µg/ml had no influence on endothelial cells, TMC, or RPE when exposed for up to 24 hours (MIC90 is 0.25-2.5 µg/ml)(Kernt et al, 2009).
    Cancer Applications

    The trend in cancer treatment is the search for antineoplastic potential of existing compounds.  A good candidate is Moxifloxacin, and researchers reviewed novel Moxifloxacin conjugates with fatty acids and verified the metabolic profile in SW480, SW620 and PC3 cell lines.  The cytotoxic potential of these conjugates can be beneficial in oncological studies.

    Moxifloxacin displayed anti-tumor activity against many cancer cell lines (Barot et al, 2012).
