complementarity of the two drug classes – praziquantel and artemisinin deriv-atives – we designed new molecules, named trioxaquantels®, that combine the 1,2,4-trioxane unit responsible for the activity of artemisinin, and the pyrazinoisoquinoline moiety of praziquantel within a single drug. The synthesis of these new drugs and their preliminary evaluation in mice infected with Schistosoma mansoni is reported
