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).
