The bifunctional enzyme N5,N10-methylenetetrahydrofolate dehydrogenase/cyclo hydrolase (FolD) is essential for growth in Trypanosomatidae. We sought to develop inhibitors of Trypanosoma brucei FolD (TbFolD) as potential antiparasitic agents. Compound 2 was synthesized, and the molecular structure was unequivocally assigned through X-ray crystallography of the intermediate compound 3. Compound 2 showed an IC50 of 2.2 ?M, against TbFolD and displayed antiparasitic activity against T. brucei (IC50 49 ?M). Using compound 2, we were able to obtain the first X-ray structure of TbFolD in the presence of NADP+ and the inhibitor, which then guided the rational design of a new series of potent TbFolD inhibitors.
