Abstract

Two optically active (100% enantiomeric excess) isomers of ofloxacin [(+/-)-ofloxacin; DL-8280; (+/-)-9-fluoro-2,3-dihydro-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-7 H-pyrido[1,2,3-de] [1,4] benzoxazine-6-carboxylic acid] were prepared by use of their optically resolved synthetic intermediates. One of the isomers, (-)-ofloxacin, was 8 to 128 times more potent in inhibiting the multiplication of gram-positive and gram-negative bacteria than the other, (+)-ofloxacin, and approximately two times more active than the racemate, (+/-)-ofloxacin.

摘要

通过使用其光学拆分的合成中间体制备了氧氟沙星的两种旋光异构体（对映体过量100%）[（±）-氧氟沙星；DL-8280；（±）-9-氟-2,3-二氢-3-甲基-10-（4-甲基-1-哌嗪基）-7-氧代-7H-吡啶并[1,2,3-de][1,4]苯并恶嗪-6-羧酸]。其中一种异构体，（-）-氧氟沙星，在抑制革兰氏阳性菌和革兰氏阴性菌繁殖方面的效力比另一种异构体（+）-氧氟沙星高8至128倍，并且比消旋体（±）-氧氟沙星的活性约高两倍。
