    Arbekacin Sulfate

    ¥3,117.50

    Arbekacin Sulfate (syn: Habekacin Sulfate) is a semisynthetic aminoglycoside antibiotic derived from kanamycin. It was discovered in 1972 orginally synthetized from dibekacin in 1973 (Hamao Umezawa). Its general structure is characterized by two or more aminosugars linked by glycosidic bonds to an aminocyclitol scaffold. Arbekacin is not inactivated by aminoglycoside-inactivating enzymes and shows concentration-dependent effects. Aminoglycoside-induced nephrotoxicity and ototoxicity is not well understood. Understanding the mechanisms of toxicity at the cellular/subcellular level may help in discovery of high-efficacy and low-toxicity aminoglycosides.

    Arbekacin Sulfate is very soluble in water.

    Mechanism of Action Arbekacin irreversibly binds to bacterial 30S and 16S ribosomal subunits thus inhibiting protein synthesis. Aminoglycosides such as bind to the bacterial 30S ribosomal subunit, causing misreading of tRNA which leaves the bacterium unable to synthesize proteins.
    Spectrum Arbekacin has broad-spectrum activity against Gram-positive bacteria such as methicillin-resistant Staphyloccus aureus (MRSA) and Gram-negative bacteria such as Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumonia. It has a synergistic effect in combination with beta-lactams and has activity against multidrug-resistant strains and A. aeruginosa and Acinetobacter baumannii.
    Microbiology Applications

    Arbekacin 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.
