  Synthesis and activity of cephalosporins containing an oxyiminomethylene functionality in the ortho-position of a phenyl- or phenoxyacetic acid C-7 side chain substituent

  摘要：

  A new series of cephalosporins having in the C-7 side chain a phenyl- or a phenoxyacetamido group bearing an oxyiminomethyl function in the ortho-position of the aromatic ring was prepared. Their in vitro activity was tested against both Gram+ and Gram- strains. (C) 1998 Elsevier Science S.A. All rights reserved.
