  • Publication number: 20050059612
    Abstract: Novel bicyclic carbohydrate compounds are effective for the prophylaxis and treatment of diseases caused by infections of the alphaherpesvirinae HSV-1 and HSV-2. The invention includes the compound wherein X1, X2, and X3 are selected from the group consisting of O, N, and S; wherein Y1 and Y2 are selected from the group consisting of O, N, and S; and wherein Z is selected from the group consisting of F, Cl, and Br, as well as analogs, prodrugs and pharmaceutically acceptable salts thereof, together with pharmaceutical compositions for the prophylaxis and treatment of diseases caused by infections of alphaherpesvirinae.

  • Publication number: 20050059647
    Abstract: 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.
