  • Publication number: 20110206636
    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 specifically have efficacy as treatments for hepatitis C viral infections.

  • Patent number: 7368475
    Abstract: The synthesis and study of biological activity of a series of new molecules with potential antimicrobial activity are described. The molecules are bicyclic carbohydrates, based on furanose sugars. Their antimicrobial activity against viruses is demonstrated, next to cytostatic effects. Significantly, a high and selective activity against Cytomegalovirus was observed.

  • Publication number: 20080057047
    Abstract: Bacteria of the sp. Bacillus that produce a lipopeptide are found to be effective in the treatment and prophylaxis of gastro-intestinal disease when administered as a probiotic. In particular, a strain of Bacillus bacteria identified as PB6 is useful for the treatment of Antibiotic Associated Diarrhea (AAD) or the more serious condition Clostridium difficile associated diarrhea (CDAD) when administered as a probiotic. Additionally, these bacteria have been found efficient for the treatment of immunorelated diseases such as Inflammatory Bowel Disease (IBD).

  • Patent number: 7125854
    Abstract: The use of bicyclic carbohydrates for the treatment of parasite infections is described. Different bicyclic carbohydrates have been tested in vitro against a number of protozoa. These compounds also have been screened against viruses, tumors, bacteria and fungi. Compound A1, a thiophenyl-containing bicyclic carbohydrate possessed significant activity against Trypanosoma brucei rhodiense, a parasite that causes the lethal sleeping sickness. Compound A2 and Compound A3, bicyclic carbohydrates with halogen containing aryl groups, possessed significant activity against Leishmania donovani, a parasite that causes leishmaniasis. Bicyclic carbohydrates in general, and Compound A1, Compound A2 and Compound A3 more specifically, could be possible treatments for the sleeping sickness and leishmaniasis in the future.
