Evaluation of Jatropha isabelli natural products and their synthetic analogs as potential antimalarial therapeutic agents.

Protozoal diseases such as malaria are a leading world health concern. We screened a library of fractionated natural products to identify new potential therapeutic leads and discovered that jatrophone (a product of Jatropha isabelli) exerts significant activity against Plasmodium falciparum strains 3D7 and K1. A focused jatrophone-scaffold library was synthesized to evaluate jatrophone's mode of action and identify more selective analogs.
