Clinafloxacin是一个喹诺酮羧酸类的广谱抗生素，目前用于严重感染的静脉注射和口服治疗。 Clinafloxacin是一个新型的氟喹诺酮。在体外具有抗革兰氏阳性，革兰氏阴性，和厌氧病原体的广谱活性。Clinafloxacin对肺炎链球菌7785 (MIC，0.125 微克/毫升)具有较高活性，并且非gyrA 或parC喹诺酮耐药突变单独对该活性具有更好的作用。与ofloxacin，levofloxacin，sparfloxacin，grepafloxacin，以及trovafloxacin相比，Clinafloxacin被认为是最有效的抗S. pneumoniae氟喹诺酮，目前被认为是一个抗肺炎链球菌药。
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.
