Interferon (IFN)-alpha monotherapy, as well as the more effective combination therapy of IFN-alpha and ribavirin, are currently used for patients with chronic hepatitis C caused by hepatitis C virus (HCV) infection, although the mechanisms of the antiviral effects of these reagents on HCV remain ambiguous, and side effects such as anemia due to the administration of ribavirin present a problem for patients who are advanced in years. Using a recently developed reporter assay system in which genome-length dicistronic HCV RNA encoding Renilla luciferase gene was found to replicate efficiently, we found that mizoribine, an imidazole nucleoside, inhibited HCV RNA replication. The anti-HCV activity of mizoribine (IC50: approximately 100 microM) was similar to that of ribavirin. Using this genome-length HCV RNA replication monitor system, we were the first to demonstrate that the combination of IFN-alpha and ribavirin exhibited more effective anti-HCV activity than the use of IFN-alpha alone. Moreover, we found that the anti-HCV activity of mizoribine in co-treatment with IFN-alpha was at least equivalent to that of ribavirin. This effect was apparent in the presence of at least 5 microM mizoribine. Since mizoribine is currently used in several clinical applications and has not been associated with severe side effects, mizoribine is considered to be of potential use as a new anti-HCV reagent in combination with IFN-alpha.
