    6-Aminopenicillanic Acid

    $50.00 - $81.00

    6-Aminopenicillanic Acid (syn: (+)-6-Aminopenicillanic Acid; 6-APA) is an organic dipeptide and the  chemical core or "nucleus" of penicillin antibiotics.  It was discovered in 1958  (Beecham Group, UK).  It is produced from Penicillin by Penicillin amidase.  6-Aminopenicillanic Acid, a β-lactam, is used as a starting compound for synthesis of semisynthetic Penicillins and may be substituted at the 6-amino position, resulting in a variety of antibacterial properties.  It is a precursor to Ampicillin and Amoxicillin. 

    Application 6-Aminopenicillanic Acid can be used as a a starting material to synthesize penicillin antibiotics. The compound reacts with higher amino acid Schiff bases to form the corresponding β-lactam derivatives.
    Mechanism of Action 6-Aminopenicillanic Acid interferes with the synthesis of bacterial cell walls of Gram-positive bacteria.
    Eukaryotic Cell Culture Applications The coating of (+)-6-Aminopenicillanic Acid on silver nanoparticles (6APA-AgNPs), can impart an ability to detect chromium (IV) in human erythrocytes.
    Spectrum Gram-positive bacteria.
