一般描述

Chemical structure: fluoroquinolone

应用

Difloxacin is a fluoroquinolone antibiotic commonly used in veterinary medicine. It is a potential treatment for Chlamydia trachomatis infections and chronic Q fever in humans. It has been used to study how potential supplementation (magnesium) may reduce quinolone-induced damage in the horse and dog models.

生化/生理作用

Difloxacin inhibits bacterial DNA gyrase and the topoisomerase II enzyme, which inhibits DNA replication and transcription

The in vitro activity of temafloxacin (A-62254), a new quinolone antibiotic, against 13 strains of Chlamydia trachomatis was determined and compared with those of doxycycline, norfloxacin, ciprofloxacin, and difloxacin. Temafloxacin and difloxacin were the most active quinolones tested, with bactericidal

Aryl-fluoroquinolone derivatives A-56619 (difloxacin) and A-56620 were found to inhibit human peripheral blood mononuclear cell (MNC) proliferation (measured by [3H]thymidine uptake) that was induced by concanavalin A or monoclonal antibody OKT3. These antimicrobial agents exert their maximum suppressive effect when

A simple and cost effective sample pre-treatment method, dispersive liquid-liquid microextraction (DLLME), has been developed for the extraction of six fluoroquinolones (FQs) from chicken liver samples. Clean DLLME extracts were analyzed for fluoroquinolones using liquid chromatography with diode array detection
