Abstract
Cefoperazone A, the principal metabolite of cefoperazone, was found to have an antimicrobial activity ranging from slightly below to 16-fold less than that of the parent drug. Like cefoperazone, the metabolite is bactericidal, penetrates well into bacterial cells, and has moderate beta-lactamase stability, some strains of members of the family Enterobacteriaceae produce an inoculum effect on the metabolite activity.
