Description

Application

Atovaquone inhibits the cytochrome bc(1) complex via interactions with the Rieske iron-sulfur protein and cytochrome b in the ubiquinol oxidation pocket. In addition to its use as a treatment for toxoplasmosis, atovaquone has antimalarial properties and prevents pneumocystis pneumonia post-renal transplant.

Biochem/physiol Actions

Atovaquone in an anti-protozoal mitochondrial electron transport inhibitor. It also functions as an antimalarial and antipneumocystic agent.

Atovaquone is an anti-protozoal mitochondrial electron transport inhibitor; Antimalarial; Antipneumocystic, and has also been used to treat toxoplasmosis. It is an analog of protozoan mitochondrial protein ubiquinone, and acts by inhibiting the cytochrome bc(1) complex via interactions with the Rieske iron-sulfur protein and cytochrome b in the ubiquinol oxidation pocket.
