Cefbuperazone is a second-generation cephalosporin antibiotic.

ChEBI: Cefbuperazone is a second-generation cephamycin antibiotic having [(1-methyl-1H-tetrazol-5-yl)sulfanyl]methyl and {N-[(4-ethyl-2,3-dioxopiperazin-1-yl)carbonyl]-D-threonyl}amino side groups located at positions 3 and 7beta respectively. It is a peptide and a cephalosporin.

Cefbuperazone is a semisynthetic cephamycin antibiotic with properties similar to those of cefoxitin, but somewhat more active against B. fragilis and enterobacteria. It is not hydrolyzed by common β-lactamases and as a result its activity is not affected by inoculum size. It is not active against cefoxitin-resistant strains. It is available in Japan.
