摘    要:1-环丙基-6,7-二氟-8-甲氧基-1,4-二氢.4-氧代喹啉.3-羧酸乙酯依次经醚键断裂、酯化、二氟甲基醚化得1.环丙基-6,7-二氟-8-二氟甲氧基-1,4-二氢-4-氧代喹啉.3-羧酸乙酯,然后经过螫合、与[1S,6S]-2.叔丁氧羰基.2,8.二氮杂双环[4,3,0]壬烷缩合、最后脱除叔丁氧羰基保护得到1-环丙基.8.二氟甲氧基-7-[(1S,6S).2,8.二氮杂双环[4,3,0]壬烷.8.基]-6-氟.1,4-二氢-4-氧代喹啉-3-羧酸。目标化合物的结构经核磁共振氢谱和质谱(ESI)所确证,并测定了其体内外抗菌作用,结果表明该化合物优于对照药环丙沙星,与莫西沙星相当或略优,尤其对肺炎链球菌29074的体内活性突出,值得深入评价。

关 键 词:喹诺酮  莫西沙星类似物  合成  抗菌作用

Abstract:1-cyclopropyl-7-(S,S)-2,8-diazabicyclo4.3.0non-8-yl-6-fluoro-8-difloro-methoxy-1,4-dihydro-4-oxo-3-quinoline carboxylic acid was prepared and evaluated for antibacterial activity in vitro and in vivo. The compound had better activity than ciprofloxacin in vitro and has similar activity as or better activity than moxifloxacin in vitro and in vivo. Especially against S.pneumoniae 29074, the compound and moxifloxacin have i.v. ED50 of 1.84 and 3.67mg/kg respectively. Consequently, the compound was selected as candidate for further evaluation.
Keywords:Quinolone   Analogue of moxifloxacin   Synthesis   Antibacterial activity
