Is the AT-rich DNA of malaria parasites a drug target?

A recent antimalarial screen by Alder and colleagues has uncovered a natural product, PDE-I2, with DNA-binding and schizonticidal activity against Plasmodium falciparum. Parasite specificity is likely conferred by the extremely high A+T content of the P. falciparum genome. We discuss here this character as a potential target for future drugs.
