制备方法与用途

概述

氨氟沙星与其他抗生素无交叉耐药性。其化学结构特点是在喹啉环的6位上导入了氟,而7位都连有哌嗪基的衍生物,使原本亲脂性的吡酮类药物增加了适度的亲水性,降低了蛋白结合率,提高了生物利用度。与第一代及第二代喹诺酮类相比,氨氟沙星的抗菌谱明显扩大,抗菌活性显著增强。

用途

氨氟沙星是一种第三代喹诺酮类药物,其抗菌作用机制是对细菌的DNA和RNA合成均有显著抑制作用。

生物活性

Amifloxacin(Win49375)是一种合成的喹诺酮类抗菌剂。

靶点

抗菌

体外研究

氨氟沙星(WIN 49375)对铜绿假单胞菌有活性,且对金黄色葡萄球菌表现出中等活性,最低抑菌浓度(MIC)小于或等于2 μg/mL。

体内研究

氨氟沙星经口服后活性显著,其半数有效剂量在两到三倍范围内与静脉给药相当。通过腹腔内感染小鼠,并于0.5小时后进行皮下、静脉和口服给药,观察到氨氟沙星的半数有效剂量(ED50)分别为0.6、0.8 和1.0 mg/kg。放射性标记的氨氟沙星在大鼠口服20 mg/kg后的血中药物浓度峰值出现在0.5小时后,相当于7.1±0.26 μg/mL。从0.75到4小时内,血中药物浓度迅速下降,从7.0±0.25 μg/mL降至1.2±0.12 μg/mL;而在8至48小时内,药物在血液中的浓度下降速度变慢且更为复杂。48小时后,血中药物浓度相当于0.14±0.02 μg/mL。

静脉给药大鼠20 mg/kg的放射性标记氨氟沙星后的血中药物浓度在1分钟时为29.1±0.85 μg/mL,在10分钟后降至14.4±0.52 μg/mL。从0.25到4小时内,血中药物浓度呈对数线性下降,从13.0±0.42 μg/mL降至0.97±0.09 μg/mL;在4至24小时内,药物的消除速度变慢且更为复杂。24小时后,血中药物浓度相当于0.12±0.01 ug/mL。

    Novel amino-substituted 3-quinolinecarboxylic acid antibacterial agents: synthesis and structure-activity relationships
    摘要:
    A series of novel 3-quinolinecarboxylic acid derivatives have been prepared and their antibacterial activity evaluated. These derivatives are characterized by fluorine attached to the 6-position and substituted amino groups appended to the 1- and 7-positions. Structure-activity relationship studies indicate that antibacterial potency is greatest when the 1-substituent is methylamino and the 7-substituent is either 4-methyl-1-piperazinyl, 16, or 1-piperazinyl, 21. Derivatives 16 and 21, the 1-methylamino analogues of pefloxacin and norfloxacin, respectively, show comparable in vitro and in vivo antibacterial potency to these two known agents. The activity (vs. Escherichia coli Vogel) of 16 (amifloxacin) is the following: in vitro MIC (microgram/mL) = 0.25; in vivo (mice) PD50 (mg/kg) = 1.0 (po), 0.6 (sc).
