- 產(chǎn)品描述： Clinafloxacin (AM 1091) is a potent and broad-spectrum fluoroquinolone antibiotic, has inhibitory activity against gram-positive, gram-negative bacterias, and anaerobic pathogens in vitro. Clinafloxacin is against DNA gyrase and topoisomerase IV of S. aureus with IC50 values of 0.92 µg/ml and 1.62 µg/ml, respectively
- 靶點(diǎn)： Quinolone
- 體內(nèi)研究： Clinafloxacin is very effective for the therapy of penicillin-resistant, ciprofloxacin-susceptible pneumococcal meningitis in the rabbit model. With the CS strain (2349)(Clinafloxacin MIC=0.12 μg/ml), at a dose of 10 mg/kg and 20 mg/kg per day Clinafloxacin achieves an initial reduction at 6 hr. Both are bactericidal at this point but presents regrowth at 24 hr, and the final reduction at 24 hr in mean log cfu/ml is 22.30 and 23.83, respectively. However, With the CR strain (4371)(Clinafloxacin MIC=0.5 μg/ml), Clinafloxacin even at 20 mg/kg per day does not decrease bacterial titers at any time point in this rabbit model of meningitis.
