A series of tetracyclic and tricyclic trioxane dimers has been prepared with ether and ester tethers of varying length and flexibility. Several of these trioxane dimers have been found to have potent and potentially therapeutically valuable antimalarial, antiproliferative, and antitumor activities in vitro.

The anti-malarial activity of all trioxanes, except 37 and 38, was evaluated in vitro against chloroquine-sensitive and chloroquine-resistant Plasmodium falciparum parasites. Trioxanes 11 and 21 were as active as artemisinin (1). It was found that neither the lactone function nor rings B and D of 1 were essential for activity. A possible pharmacophore for artemisinin-like activity, which embodies a
