Abstract: Disclosed are methods, compounds, and compositions for treating infection by an Apicomplexan parasite that include administering a compound that selectively inactivates ornithine aminotransferase of the Apicomplexan parasite. Specifically, the methods, compounds, compounds may be utilized for treating infection by Toxoplasma gondii and toxoplasmosis and for treating infection by Plasmodium falciparum and malaria. The compounds disclosed herein are observed to selectively inactivate Toxoplasma gondii ornithine aminotransferase (TgOAT) relative to human OAT and relative to human ?-aminobutyric aminotransferase (GABA-AT).

Abstract: This invention relates uses of Toxoplasma gondii chorismate synthase, a component components of plant-like metabolic pathways not including psbA or PPi phosphofructokinase and not generally operative in animals or encoded by the plastid DNA, in assays to develop compositions that interfere with Apicomplexan growth and survival. Components of the pathways include enzymes, transit peptides and nucleotide sequences encoding the enzymes and peptides, or promoters of these nucleotide sequences to which antibodies, antisense molecules and other inhibitors are directed. Diagnostic and therapeutic reagents and vaccines are developed based on T. gondii chorismate synthase and its inhibitors.
