Arprinocid: An Anticoccidial Agent against Toxoplasma gondii

Arprinocid is an anticoccidial agent. Arprinocid and its main metabolite, arprinocid-1-N-oxide, have been found to exert cidal effect on Toxoplasma gondii in vitro. However, the exact mechanism of action is unknown. (The product is for research purpose only.)
