Cadrofloxacin, also known as Caderofloxacin and CS-940, is a novel fluoroquinolone antibacterial. The activities of CS-940 against gram-positive cocci and gram-negative rods, including methicillin-susceptible Staphylococcus aureus and penicillin-resistant Streptococcus pneumoniae, were comparable to those of tosufloxacin, with MICs at which 90% of the strains were inhibited (MIC90s) of 0.5 microg/ml or less. Against methicillin-resistant S. aureus, CS-940 was as active as tosufloxacin, with a MIC90 of 16 microg/ml. The efficacy of CS-940 against murine respiratory infections due to S. pneumoniae or Haemophilus influenzae was better than those of tosufloxacin and sparfloxacin. The efficacy of oral doses of CS-940 reflected not only potent in vitro activity but also a high transmigration ratio from the bloodstream to lung tissues.
