    Secnidazole

    ¥25,907.78

    Secnidazole is a second-generation 5-nitroimidazole antibiotic and analog of metronidazole. It has in vitro activity against anaerobic bacteria and can be used in research for trichomoniasis, amoebiasis, giardiasis, and bacterial vaginosis. The compound is structurally related to metronidazole and tinidazole. Secnidazole is a 'prodrug' thus bacterial enzymes reduce its nitro group to radical anions that interfere with bacterial DNA synthesis.

    Secnidazole is freely soluble in methanol, ethanol, acetone and chloroform.

    Mechanism of Action

    Similar to other 5-nitroimidazoles, the antimicrobial properties are due to the nitro group in the imidazole ring. Once it enters the bacteria or parasite, it is activated by host nitroreductase enzymes to form radical anions and reactive intermediates. These cause damage to the DNA helix, disrupt protein synthesis/replication, adn ultimately cell death.

    It can inhibit quorum sensing (QS) thus it can attenuate the pathogenesis of Pseudomonas aeruginosa.

    Spectrum Secnidazole has broad spectrum vitro antimicrobial activity. Gram-positive and Gram-negative bacteria, along with protozoa are susceptible.
    Eukaryotic Cell Culture Applications Secnidazole was cultured with human hepatocytes to assess metabolic profiling, and was found the agent has minimal to no potential in vitro interactions with other compounds.
    Molecular Formula C7H11N3O3
