CEPHEM DERIVATIVES AND A METHOD FOR PRODUCING THE COMPOUNDS AND AN ANTIBACTERIAL COMPOSITION CONTAINING THE COMPOUNDS

摘要

The present invention relates to novel cephem derivatives in which known phenyl oxazolidinone derivatives are chemically combined with cephem, a process for producing the cephem derivatives, and a pharmaceutical antibacterial composition containing the cephem derivatives. The structural formula of the cephem derivatives compounds is represented as in formula (I).
