生物活性
Fleroxacin (Ro 23-6240, AM-833) 是一种新型广谱喹诺酮类。
体内研究
Fleroxacin (Ro 23-6240) is a new trifluorinated quinolone exhibiting high activity against a broad spectrum of gram-negative and gram-positive bacteria. Fleroxacin is characterized pharmacokinetically by a long elimination half-life (9 to 10 h) and high concentrations in plasma (e.g., maximum concentration of 2.3 micrograms/ml after an oral dose of 200 mg). Fleroxacin (Ro 23-6240) is effective against Haemophilus ducreyi in vitro. Fleroxacin (Ro 23-6240), 200 or 400 mg as a single oral dose, is efficacious therapy for microbiologically proven chancroid in patients who do not have concurrent HIV-1 infection. Among HIV-1-infected men, a single dose of 200 or 400 mg of fleroxacin is inadequate therapy for chancroid.
化学性质
急性毒性LD50小鼠,大鼠,犬(mg/kg):>4000,>4000,>1000口服。急性毒性LD50小鼠(mg/kg):217~237静脉注射。
盐酸氟罗沙星(Fleroxacin Hydrochloride):Cl7H18F3N3O3?HCl。在水中结晶,熔点269~271℃(分解)。
用途
喹诺酮类抗菌药,通过抑制细菌的DNA促旋酶而起杀菌作用。和其它抗生素之间无交叉耐药性,适用于敏感菌引起的淋球菌性尿道炎、急性支气管炎、慢性支气管炎的急性发作、肺炎、膀胱炎、肾盂肾炎、前列腺炎、慢性复杂性尿路感染、伤寒、细菌性痢疾、皮肤软组织感染以及腹腔感染等。
