| In vitro study | Atovaquone (atavaquone) is a naphthalene compound. Atovaquone is hydroxy-1, 4-naphthoquinone, a ubiquinone analog, which has activity against Pneumocystis. Atovaquone is an antigenic insect mitochondrial electron transfer inhibitor, an antimalarial agent, an anti-Pneumocystis, and is also used in the treatment of toxoplasmosis. It works by interacting with Rieske iron-sulfur proteins and cytochrome B in the ubiquinone oxidation pocket, inhibiting the cytochrome bc(1) complex. |
| In vivo study | Atovaquone is a unique naphthoquinone with a broad spectrum of antiprotozoal activity. It is effective for the treatment and prevention of Pneumocystis carinii pneumonia (PCP), it is effective for the treatment and prevention of malaria in combination with proguanil, and it is effective for the treatment of babesiosis in combination with azithromycin. |
