ABSTRACT:
Novel 7.alpha.-methoxycephalosporin derivatives having a high antimicrobial activity. They are useful for the medical treatment of diseases infected by gram-positive bacteria and gram-negative bacteria. More particularly, they show an antimicrobial activity against bacteria such as Eschericha coli Proteus, Citrobacter and Enterobacter which bacteria have resistance to the conventionally employed cephalosporins, and they are effective for the medical treatment of diseases infected by these bacteria. Such 7.alpha.-methoxycephalosporin derivatives are prepared by a relatively simple method.
