Clinafloxacin (AM 1091) 是一种高效广谱氟喹诺酮类抗生素 (antibiotic)，对革兰氏阳性、革兰氏阴性和厌氧病原体均有抑制活性。Clinafloxacin 对金黄色葡萄球菌的 DNA 促旋酶 (DNA gyrase) 和拓扑异构酶 IV (topoisomerase IV) 有抑制作用，IC₅₀ 值分别为 0.92 µg/ml 和 1.62 µg/ml。

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 IC 50 values of 0.92 μg/ml and 1.62 μg/ml, respectively.

Quinolone

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.
has not independently confirmed the accuracy of these methods. They are for reference only.

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.
has not independently confirmed the accuracy of these methods. They are for reference only.
