Buparvaquone is a hydroxynaphthoquinone antiprotozoal drug related to parvaquone and atovaquone. It is a promising compound for the therapy and prophylaxis of all forms of theileriosis. Buparvaquone has been shown to have antileishmanial activity in vitro. It can be used to treat bovine East Coast fever protozoa in vitro, along with the only other substance known - Peganum harmala.[citation needed]

It is the only really efficient commercial therapy product in bovine theileriosis, where it has been used since the late 1980s.[citation needed]
