The human malaria parasite Plasmodium falciparum is responsible for the death of more than a million people each year. The emergence of strains of this malaria parasite resistant to conventional drug therapy has stimulated the search for antimalarials with novel modes of action. Fosmidomycin has proved to be efficient in the treatment of uncomplicated P. falciparum malaria in recent clinical trials conducted in Gabon and Thailand. It has a novel mode of action through the inhibition of 1-deoxy-D-xylulose 5-phosphate reductoisomerase (DXR), an enzyme of the non-mevalonate pathway of isoprenoid biosynthesis, which is absent in humans. In this study, we have successfully determined the crystal structures of P. falciparum DXR (PfDXR) in complex with alpha-aryl substituted fosmidomycin analogues, some of which have higher inhibitory activities (15 to 100 nM) against PfDXR. We expect present structures to be useful guides for the design of more effective antimalarial compounds.
