Abstract

Thirty-three N-acyl 1,2,4-dispiro trioxolanes (secondary ozonides) were synthesized. For these ozonides, weak base functional groups were not required for high antimalarial potency against Plasmodium falciparum in vitro, but were necessary for high antimalarial efficacy in Plasmodium berghei-infected mice. A wide range of LogP/D(pH)(7.4) values were tolerated, although more lipophilic ozonides tended to be less metabolically stable.
