title: Inhibition of in vitro HBsAg production by amphotericin B and ketoconazole.
abstract: The effects of amphotericin B, ketoconazole, and adenine arabinoside on production of hepatitis B surface antigen (HBsAg) particles by the human hepatoma cell line PLC/PRF/5 were examined. In addition, the effects of these drugs on cellular protein synthesis were determined. These drugs caused a dose-dependent decrease in HBsAg production that was paralleled by a decrease in cellular protein synthesis. Ketoconazole was the most active of these drugs and the most specific, causing a 72% reduction in HBsAg production with only a 38% reduction in protein synthesis. These data suggest that further studies evaluating ketoconazole for the treatment of chronic hepatitis B virus infection in animals are warranted.
