Abstract Arbidol ARB is an antiviral compound that was originally proven effective for treatment of influenza and several other respiratory viral infections. The broad spectrum of ARB anti-viral activity led us to evaluate its effect on hepatitis C virus HCV infection and replication in cell culture. Long-term ARB treatment of Huh7 cells chronically replicating a genomic length genotype 1b replicon resulted in sustained reduction of viral RNA and protein expression and eventually cured HCV infected cells. Pre-treatment of human hepatoma cells with 15 pM ARB for 24 to 48 hours inhibited acute infection with JFH-1 virus by up to 1000-fold. The inhibitory effect of ARB on HCV was not due to generalized cytotoxicity nor to augmentation of IFN antiviral signaling pathways but involved impaired virus-mediated membrane fusion.
