The mother nucleus of oxycephalosporin is mainly used for the production of laxocephalosporin and fluorocephalosporin. The antibacterial performance of laxocephalosporin is similar to that of third-generation cephalosporins, and its antibacterial spectrum is similar to that of cefotaxime. It has good antibacterial effects against various Gram negative bacteria; The antibacterial spectrum of fluoroxycephalosporin is similar to other third-generation cephalosporins, and its antibacterial effect on gram-positive bacteria is almost the same as that of laxocephalosporin. Its antibacterial performance is similar to that of the fourth generation cephalosporins. Both are correct β- Lactam enzyme has good stability.
