Malarial parasites are believed to be more susceptible to oxidative stress than their hosts. BCNU(1,3-bis(2-chloroethyl)-1-nitrosourea) and HeCNU(1-(2-chloroethyl)-3-(2-hydroxythyl)-1-nitrosourea), inhibitors of the antioxidant enzyme glutathione reductase, were found to prevent the growth of Plasmodium falciparum in all intraerythrocytic stages. When exposing infected red blood cells to 38 microM BCNU or 62 microM HeCNU for one life cycle of synchronously growing parasites, the parasitemia decreased by 90%. During the formation of new ring forms, the parasites are even more susceptible to these drugs. The treatment with BCNU or HeCNU produced a rapid depletion of GSH in the parasites and their host cells; in addition, protection against lipid peroxidation was impaired in these cells. Possible mechanisms for the antimalarial action of the inhibitors are discussed. Our results suggest that erythrocyte glutathione reductase, an enzyme of known structure, might be considered as a target for the design of antimalarial drugs.
