Nine orally active novel artemisinin derivatives were prepared from artemisinin by four-step synthesis, and the compounds were evaluated in the rodent model using multidrug resistant Plasmodium yoelii nigeriensis. All of the compounds exhibited antimalarial activities with the ED50 ranging from 5.41 mg/kg–12.4 mg/kg. Among them, artemisinin derivative bearing N-(4-hydroxy-3-((4-phenylpiperazin-1-yl)methyl)phenyl)
