MIC: 1 μg/ml (parC-gyrA mutants, S. pneumonia )
Clinafloxacin exhibits activity against S. pneumonia with an MIC of 1μg/ml for the parC-gyrA mutants.Clinafloxacin hydrochloride has antibacterial activities against target-altered mutant strains of S. aureus . It against Wild type S. aureus , gyr A mutant S. aureus and gyr A mutant S. aureus with MIC values of 0.016 µg/ml, 0.063 µg/ml and 0.915 µg/ml, respectively.
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.
