摘要:
An important intermediate for preparing cephalopsporin antibotics, 7-aminodesacetoxy cephalosporanic acid (7-ADCA), is prepared by a novel bioprocess in which a transformed Penicillium chrysogenum strain is cultured in the presence of an adipate feedstock to produce adipoyl-6-APA (6-amino penicillanic acid); and the in situ expression of an expandase gene, e.g., from Streptomyces clavuligerus , with which the P.chrysogenum has been transformed, converts the adipoyl-6-APA by ring expansion to the novel compound adipoyl-7-ADCA. The final product, 7-ADCA, is then prepared by cleavage of the adipoyl side chain using an adipoyl acylase. The entire synthesis, accordingly, is carried out using bioprocesses, and is efficient and economical.
