Function

DrugBank ID:

DB01117


Description:

Atovaquone is a hydroxynaphthoquinone, or an analog of ubiquinone, that has antimicrobial and antipneumocystis activity. It is being used in antimalarial protocols. [DrugBank]

Targets:

Cytochrome b (Plasmodium falciparum); Dihydroorotate dehydrogenase (quinone), mitochondrial (Plasmodium falciparum (isolate 3D7)); Dihydroorotate dehydrogenase (quinone), mitochondrial (Humans) [DrugBank]

Pharmacodynamics:

Atovaquone is a highly lipophilic drug that closely resembles the structure [ubiquinone]. Its inhibitory effect being comparable to ubiquinone, atovaquone can act by selectively affecting mitochondrial electron transport and parallel processes such as ATP and pyrimidine biosynthesis in atovaquone-responsive parasites. Cytochrome bc1 complex (complex III) seems to serve as a highly discriminating molecular target for atovaquone in Plasmodia. There is no significant risk for myelosuppression associated with atovaquone, making this drug a beneficial therapeutic agent for recipients of bone marrow transplantation. [DrugBank]
