    Maduramicin Ammonium

    2,705,950.00Rp - 9,412,000.00Rp

    Maduramicin Ammonium is prepared from Maduramicin by taking advantage of the acidic carboxylic acid which ionizes and readily forms a salt complex in ammonium hydroxide solutions. This formulation is preferred in animals to enhance growth and prevent coccidiosis.  Maduramicin is an ionophore, forming complexes with monovalent cations, with a higher affinity for K+ than Na+.  Maduramicin Ammonium is soluble in ethanol, methanol, DMF and DMSO, but has limited water solubility.

     We also offer:

    • Maduramicin (M046)
    Application Maduramicin can be used as a positive control in compound evaluation studies and as lead compounds for chemical optimization.
    Mechanism of Action Maduramicin can form complexes with cations  (particularly Na+, K+ and Ca2+), thereby promoting their transport across the cell membrane and increasing the osmotic pressure in the coccidia, which inhibits certain mitochondrial functions such as substrate oxidation and ATP hydrolysis, eventually leading to cell death in the protozoa.

     In cell culture studies, Maduramicin was found to cause accumulation of the cells at G0/G1 phase of the cell cycle, and induce cellular apoptosis. It can also downregulate protein expression of cyclin D1, cyclin-dependent kinases, and upregulate expression of CDK inhibitors.

    Spectrum It is effective against Gram-positive bacteria, and exhibits a broad-spectrum of anticoccidial activity against the most frequently occurring Eimeria species, and is also active Cryptosporidium and Treponema.
    Microbiology Applications Maduramicin is currently used to combat coccidiosis in poultry.
    Eukaryotic Cell Culture Applications Using mouse myoblasts (C2C12) and human rhabdomyosarcoma (RD and Rh30) cells as an experimental model, Maduramicin was found to inhibit proliferation and induce apoptosis in a dose-dependent fashion.

    A chemiluminescence immunoassay (CLIA) was developed to detect Cryptosporidium parvum growth in Madin-Darby canine kidney (MDCK) cell cultures. Maduramicin was found to have selective activity against C. parvum in a dose-dependent manner. CLIA offers advantages over conventional enzyme-linked immunosorbent assay and immunofluorescence assay methods in that it is more sensitive and efficient. It is an efficient tool for evaluating potential anti-cryptosporidial compounds prior to testing in animal models.

    Solubility Soluble in ethanol, methanol, DMF and DMSO, but limited water solubility.
