| In vitro study | Clinafloxacin is a broad-spectrum antibiotic of the quinolone carboxylic acid class that is currently used for intravenous and oral treatment of serious infections. Clinafloxacin is a new type of fluoroquinolone. It has broad spectrum activity against Gram-positive, Gram-negative, and anaerobic pathogens in vitro. Clinafloxacin had high activity against Streptococcus pneumoniae 7785 (MIC,0.125 μg/ml), and non-gyrA or parC quinolone-resistant mutations alone had a better effect on this activity. Compared to ofloxacin,levofloxacin,sparfloxacin,grepafloxacin, and trovafloxacin, Clinafloxacin is considered the most effective fluoroquinolone against S. pneumoniae and is currently considered an antistreptococcus pneumoniae drug. |
| In vivo study | 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. |
