This invention relates to new methods of treating parasitic infections, such as trichomonas vaginalis infection and cecum amoeba infection, using L-enantiomer enriched ornidazole, in particular enantiomerically pure L-ornidazole, which provides benefits such as higher efficacy and lower toxicity to central nervous system over the existing racemic Ornidazole drug. New methods of synthesizing L- and D-enantiomers of Ornidazole in high purity and enantiomeric excess (ee), new formulations of the enantiomerically enriched L- or D-ornidazole, as well as their preparation processes and methods of use, are also disclosed.
本发明涉及使用L-对映体富集的奥硝唑新方法治疗寄生虫感染,如阴道滴虫感染和盲肠阿米巴感染,特别是使用对映纯L-奥硝唑,其提供了比现有的混合对映体奥硝唑药物更高的疗效和更低的对中枢神经系统的毒性的优点。本发明还揭示了高纯度和对映体过量(ee)的L-和D-奥硝唑的新合成方法,对映体富集的L-或D-奥硝唑的新配方,以及它们的制备过程和使用方法。
