Uses

Artesunate (CAS NO.88495-63-0) can be used primarily as treatment for malaria; but artesunate has also been shown to be >90% efficacious at reducing egg production in Schistosoma haematobium infection.

Production

Artesunate (CAS NO.88495-63-0) is prepared from Dihydroartemisinin (DHA) by reacting it with SUCCINIC ACID anhydride in basic medium. Pyridine as base/solvent, sodium bicarbonate in chloroform and catalyst DMAP (N,N-dimethylaminopyridine) and triethylamine in 1,2-dichloroethane have been used, with yields of up to 100%. A large scale process involves treatment of DHA in dichloromethane with a mixture of pyridine, a catalytic amount of DMAP and SUCCINIC ANHYDRIDE. The dichloromethane mixture is stirred for 6–9 h to get artesunate in quantitative yield. The product is further re-crystallized from dichloromethane.
