Abstract:
:Interferon alpha-2b (IFN) alone or in combination with Ribavirin is approved in the United States for the treatment of chronic hepatitis C virus (HCV) infection. We have previously reported that the glucosidase inhibitor, n-butyl deoxynojirimycin (nB-DNJ) inhibits the production of infectious bovine diarrhea virus (BVDV) (Proc. Natl. Acad. Sci. 96 (1999) 11878). Since BVDV has been used as a model for HCV and grows productively in tissue culture, and IFN and glucosidase inhibitors are thought to act at different steps in the virus life cycle, it was of interest to determine the antiviral impact of combining nB-DNJ with IFN. Using plaque reduction and single-step growth analyses of the cytopathic BVDV strain NADL, data are presented that shows human IFN inhibited BVDV production in a dose dependent manner, with 3 IU/ml inhibiting 50% of the yield of virus (IC50) when added within 1 h post infection. Under the same conditions, the glucosidase inhibitors nB-DNJ and castanospermine (CST) also prevented BVDV production in a dose dependent manner with IC50s of 226 microM and 47 microM, respectively. In combination with 138 microM nB-DNJ the apparent IC50 for IFN was 0.056 IU/ml. This 54-fold increase in IFN potency suggests that nB-DNJ can synergize with IFN. Two additional independent analyses were performed to measure combination effects which demonstrated that the combined antiviral effect of nB-DNJ and IFN were greater than would be expected for a simple additivity. These data are consistent with an interpretation that glucosidase inhibitors and IFN have a synergistic antiviral effect in tissue culture. The relevance of these finding to treatment of HCV infection is discussed.
