Abstract

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 μM, against TbFolD and displayed antiparasitic activity against T. brucei (IC₅₀ 49 μM). 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.
