Cefluprenam is an anti-bacterial agent of broad spectrum. It was active in vitro against different bacteria strains with MIC values from 0.78 ug/ml to 3.13 ug/ml. The drug exerts its bactericidal activity through inhibition of penicillin-binding proteins, showing high affinity to all four subtypes. Cefluprenam was tested for the treatment of respiratory tract infections in phase III study, however the drug development was stopped.

In Vitro Use Guide

Cefluprenam was tested against different bacteria strains. The MIC was determined by visual inspection for lack of turbidity after 24 h of incubation at 37°C. MIC90 for S. aureus and Staphylococcus epidermidis were 0.78 to 1.56 ug/ml. MIC50 for E. faecalis was 1.56 ug/ml. Enterobacteriaceae was inhibited at 0.78 ug/ml. P. vulgaris - at 3.13 ug/ml (MIC90). The MIC90s of the drug for E. cloacae, E. aerogenes, and C. freundii were 0.78, 0.05, and 0.39 ug/ml, respectively. Against S. marcescens the drug was active with MIC90 value of 3.13 ug/ml. MIC50 for P. aeruginosa was 3.13 ug/ml, etc.
