产品描述 | Gatifloxacin hydrochloride (AM-1155 hydrochloride) is an antibiotic of the fourth-generation fluoroquinolone family, which can inhibit the bacterial enzyme DNA rotase and topoisomerase IV. |
靶点活性 | Topo II:36.7 μM |
体内活性 | 所有眼睛在接种后48小时内均出现感染迹象,其中36只眼睛(占87.8%)显示出中度至重度的角膜炎。到第15天时,所有眼睛均显示角膜愈合,各组之间无显著差异。接受gatifloxacin治疗的四组中有三组的荧光素保留区域评分倾向于低于ciprofloxacin组。研究结束时,没有眼睛检测出Pseudomonas阳性。即使是每天最多给予48剂量的gatifloxacin,也没有发现角膜沉着物[1]。 |
动物实验 | Heptanol-induced corneal ulcers in New Zealand White rabbits (n = 41; 8 females/group) were inoculated with 10(6) CFU of Pseudomonas aeruginosa. Gatifloxacin 0.3% dosing varied among 4 groups with frequencies of 16-48 doses/day (days 1-2), 3-16 doses/day (days 3-7), and maintenance dosing of 3-4 doses/day (days 8-22). Ciprofloxacin 0.3% was administered as labeled for corneal ulcers, with 44 doses on day 1, 16 doses on day 2, and 4 doses/day on days 3-21[1] |
