Ecenofloxacin (CFC-222), a fluoroquinolone, is a broad-spectrum antibacterial compound acting as a ype II DNA topoisomerase inhibitor. It exerts antibacterial activities against gram-positive, gram-negative, and anaerobic organisms. Ecenofloxacin development as an antibacterial agent has been discontinued.

Sample Use Guides

In Vitro Use Guide

Ecenofloxacin (CFC-222) was more active than the other fluoroquinolones tested against gram-positive bacteria. CFC-222 was particularly active against Streptococcus pneumoniae (MIC at which 90% of isolates are inhibited [MIC90], 0.2 microg/ml), Staphylococcus aureus (MIC90, 0.2 microg/ml for ciprofloxacin-susceptible strains), and Enterococcus faecalis (MIC90, 0.39 microg/ml). Against Escherichia coli and other members of the family Enterobacteriaceae, CFC-222 was slightly less active than ciprofloxacin (MIC90s for E. coli, 0.1 and 0.025 microg/ml, respectively).
