Penicillin Acylase in the Industrial Production of β-Lactam Antibiotics
摘要:
Immobilized penicillin acylase is a biocatalyst suitable for the kinetically controlled industrial synthesis of semi-synthetic antibiotics in aqueous environments. Amoxicillin and ampicillin are obtained by condensing 6-aminopenicillanic acid with the amide or ester of D-(-)-4-hydroxyphenylglycine and D-(-)phenylglycine, respectively. Similarly, the cephalosporin antibiotics cefadroxil and cephalexin can be obtained from 7-aminodesacetoxycephalosporanic acid.
