생화학적/생리학적 작용
Orally active, 4th generation fluoroquinolone broad-spectrum antibiotic with dual DNA gyrase and topoisomerase IV inhibitory activity.
Sitafloxacin (DU-6859 or DU-6859a) is an orally active, fourth generation fluoroquinolone that exhibits broad-spectrum antibiotic activity against many Gram-positive, Gram-negative and anaerobic clinical isolates, including strains resistant to other fluoroquinolones, via dual inhibitory activity against bacterial DNA gyrase and topoisomerase IV (IC50 = 1.16 and 1.88 μg/mL against S. pneumoniae gyrA/B and parC/E, respectively). Sitafloxacin is active against methicillin-resistant staphylococci, Streptococcus pneumoniae and other streptococci with reduced susceptibility to levofloxacin and other quinolones and enterococci. Sitafloxacin also exhibits activity against clinical isolates of Klebsiella pneumoniae, Enterobacter cloacae, Pseudomonas aeruginosa as well as some activity against quinolone-resistant strains and Acinetobacter baumannii. Sitafloxacin in vitro activity against anaerobes is comparable to imipenem and metronidazole.

Purpose. Sitafloxacin (SFX) is a new fluoroquinolone (FQ) that has shown a strong bactericidal effect against Mycobacterium tuberculosis (Mtb) in vitro. However, data on SFX efficacy against Mtb with gyrA/B mutations and its epidemiological cut-off (ECOFF) value remain limited. Therefore

To detect the in vitro activities of sitafloxacin alone and in combination with rifampin, colistin, sulbactam, and tigecycline against extensively drug-resistant Acinetobacter baumannii (XDR-A. baumannii). 24 XDR-A. baumannii strains were isolated from patients' specimens. Broth microdilution assay was used to

The in-vitro inhibitory activities of sitafloxacin (DU-6859a) and other quinolones against Streptococcus pneumoniae DNA gyrase and topoisomerase IV were measured. IC50s of levofloxacin, ciprofloxacin, sparfloxacin and tosufloxacin against DNA gyrase were almost three to 12 times higher than those against
