6-Aminopenicillanic Acid or (+)-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-APA, 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.
