A means and method for treating malaria using a spiro or dispiro 1,2,4-trioxolane is described. The preferred 1,2,4-trioxolanes include a spiroadamantane group on one side of the trioxolane group, and a spirocyclohexyl or spiropiperidyl ring on the other side of the trioxolane group, whereby the spirocyclohexyl ring is preferably functionalized or substituted at the 4-position or a spiropiperidyl ring that is functionalized or substituted at the nitrogen atom. In comparison to artemisinin semisynthetic derivatives, the compounds of this invention are structurally simple, easy to synthesize, non-toxic, and potent against malarial parasites.
描述了一种利用螺环或二螺环1,2,4-三噁烷治疗疟疾的方法和手段。首选的1,2,4-三噁烷包括在三噁烷基团的一侧具有螺环戊烷基团,并在三噁烷基团的另一侧具有螺环环己基或螺环哌啶基团,其中螺环环己基环在4-位功能化或取代,或者螺环哌啶基团在氮原子处功能化或取代。与青蒿素半合成衍生物相比,本发明的化合物结构简单,易于合成,无毒,并且对疟原虫具有强效作用。
