Oxycefene nucleus is mainly used in the production of oxycefore and fluorocefore. The antibacterial properties of laoxcefin are similar to that of the third generation cephalosporin, and the antibacterial spectrum is similar to that of cefotaxime, so it has good antibacterial effect on a variety of gram-negative bacteria. The antibacterial spectrum of cephalosporin is similar to that of other third-generation cephalosporins, and its antibacterial effect on gram-positive bacteria is almost the same as that of lactobacillus, and its antibacterial property is similar to that of the fourth-generation cephalosporin. Both of them have good stability to -lactamase.
