Sesquiterpene lactones (SLs) are a class of sesquiterpenoids that contain a lactone ring. They are most often found in plants of the family Asteraceae (daisies, asters). Other plant families with SLs are Umbelliferae (celery, parsley, carrots) and Magnoliaciae (magnolias). A collection of colorless, lipophilic solids, SLs are a rich source of drugs. They can be allergenic and toxic in grazing livestock. Some are also found in corals such as Maasella edwardsi.

The use of sesquiterpenes and, in particular sesquiterpene lactone endoperoxides, such as artemisinin and analogs thereof, for the treatment of hepatitis C virus infections. Artemisinin, analogs of artemsisnin and some crude Artemisia extracts were tested in vitro against DNA-viruses, retro-viruses and Flavivirida, (an important family of human and animal RNA pathogens). These compounds were also screened for anti-tumor activity. Strong activity of artemisinin was noticed against the bovine viral diarrhea virus (BVDV). As pestiviruses, such as BVDV, share many similarities with hepatitis C virus (HCV), we can conclude that endoperoxides in general and artemisinin more specificly have efficacy as treatments for hepatitis C viral infections.
