专利号:US-6218138-B1 优先权日:1998-05-26 标 题 :Synthesis of beta-lactam antibiotics with immobilized penicillin amidase 发明人:ILHAN FERHAT; KRAEMER DIETER 权利人:UNIFAR KIMYA SANAYI VE TICARET 摘要:Beta-lactam antibiotics are synthesized by reacting an amino-beta-lactam component with a corresponding amino-group-containing acylating side-chain component in the presence of penicillin amidase from E. coli covalently immobilized on support particles. The resulting beta-lactam antibiotic product is solubilized by adding an acid such as sulfuric acid to lower the pH to 1.0 at a temperature in the range of 0° C. to +5° C. The immobilized penicillin amidase is substantially inactivated by the acid. After separating the beta-lactam antibiotic product, the immobilized penicillin amidase is substantially reactivated for reuse in antibiotic synthesis by treatment with a buffer having about a neutral pH. Antibiotics that can be produced include ampicillin, amoxicillin, cephalexin, cefaclor and cefadroxil. Support particles that can be used include particles having a macroporous structure and a particle diameter of 10-1000 mum, particles having oxirane groups, particles made of a synthetic polymer and inorganic particles such as porous glass particles.
