Sitamaquine is an orally active 8-aminoquinoline analog that exhibit antiplasmodial and antileishmanial activities. Sitamaquine accumulates in Leishmania parasites. Sitamaquine potently inhibits respiratory chain complex II (succinate dehydrogenase), which leads to an apoptosis-like death of Leishmania parasites.
Sitamaquine is also known as WR-6026. It is used in the treatment of visceral leishmaniasis.
