　　6-Aminopenicillanic acid is an important precursor for the synthesis of β-lactam antibiotics and is the main product of the hydrolysis of penicillin G (PenG) by penicillin acyltransferase (PA). It has a small inhibitory capacity and can be introduced into different side chains to obtain a variety of penicillins with different potencies. It is an important intermediate for the production of the semi-compound antipenicillin antibiotics ampicillin sodium and amoxicillin.
