Suppressive effects of destruxin B on hepatitis B virus surface antigen gene expression in human hepatoma cells

Abstract excerpt

Destruxin B, a cyclodepsipeptide was originally identified as a plant pathogen from the fungus, Alternaria brassicae. We examined the antiviral activity of destruxin B and found that it suppresses the expression of the hepatitis B viral surface antigen (HBsAg) gene in human hepatoma Hep3B cells which carry an integrated viral gene in its chromosome. In contrast, destruxin B shows no cytotoxic effect on the...
