FAQ
What is the mode of action of atovaquone?
Atovaquone inhibits parasite mitochondrial electron transport selectively. Proguanil hydrochloride works largely through its metabolite cycloguanil, which is a dihydrofolate reductase inhibitor. The malaria parasite’s dihydrofolate reductase inhibition affects deoxy thymidylate production.
Is atovaquone an antifungal?
Atovaquone displays antifungal efficacy against clinical isolates of Aspergillus and Fusarium, with Fusarium species being more susceptible to atovaquone than Aspergillus species. Atovaquone also decreased labile intracellular zinc levels and boosted Aspergillus’s sensitivity to metal shock.
Is atovaquone antiparasitic?
Atovaquone, a hydroxynaphthoquinone, was originally created as an antimalarial but is now proven to be effective against a variety of other eukaryotic microbial parasites including toxoplasma and pneumocystis. Plasmodium falciparum and P. falciparum mitochondria were cholate-lyzed.
