Malaria-infected mice are cured by a single dose of novel artemisinin derivatives.

We disclose here for the first time the curative activity of a new generation of trioxane dimers, designed logically and prepared easily from the natural trioxane artemisinin in only four or five chemical steps that would be easily accomplished also on a manufacturing scale. Four of these trioxane dimers cure malaria-infected mice after only a single subcutaneous dose, and two other dimers cure after three oral doses.
