artesunate   

GtoPdb Ligand ID: 9956

artesunate is an approved drug (FDA (2020))
Compound class: Synthetic organic
Comment: Artesunate is a semisynthetic derivative of artemisinin, a natural product isolated from the qinghao or sweet wormwood plant (Artemisia annua). It contains an unusual endoperoxide bridge, believed to be responsible for the antimalarial activity of artemisinin and its derivatives.
Artesunate is a prodrug that is converted to the active metabolite artenimol (dihydroartemisinin).

Guide to Malaria Pharmacology Comments
Artesunate has potent antimalarial activity against the asexual blood stage of P. falciparum (including chloroquine-resistant strains) and is characterised by an extremely rapid parasitemia clearance.

Artesunate is listed in the World Health Organisation's 21st Essential Medicines List (2019) as an antimalarial for use in the management of severe malaria. It is also listed as an antimalarial for curative treatment in combination with either amodiaquine, mefloquine or sulfadoxine + pyrimethamine (SP). These are three of the artemisinin-based combination therapies (ACTs) recommended in the WHO's Guidelines for the treatment of malaria [4].

Potential Target/Mechanism Of Action: As the precise mechanism of action of artesunate is not yet known, we do not have a molecular target for this compound.
