Abstract

Sixteen new anilide derivatives of the natural trioxane artemisinin were prepared and evaluated for antimalarial efficacy in Plasmodium berghei infected mice. Of these 16 new anilides administered orally as one 6 mg/kg dose combined with 18 mg/kg mefloquine hydrochloride, only sulfide 3-arteSanilide 12d was completely curative: on day 30 after infection, all mice in this group had no detectable parasitemia, gained as much weight as the uninfected control mice, and behaved normally.
