6-Aminopenicillanic Acid (6-APA): A Precursor of Many Semi-Synthetic Penicillins and Cephalosporins
6-Aminopenicillanic acid (6-APA) is a precursor of many semi-synthetic penicillins and cephalosporins-the β-lactam antibiotics. 6-APA is produced by enzymatic hydrolysis of penicillin G [P1770] [P1772].
