Abstract
Hepatitis C virus (HCV) infects about 2% of the world population. The standard treatment of chronic HCV infection is still discontented because of the low sustained virological response rate. The development of new HCV antivirals is a healthcare imperative. We explored the potentials of polyoxometalates to inhibit HCV infection using newly developed HCVcc cell culture system. We found one polyoxometalate compound (named POM-12) can inhibit HCV infection at the nanomolar range while displayed little cytotoxicity. We showed that POM-12 inhibited pseudotyped HCV infection but had no effect on HCV RNA replication. Furthermore, we showed that POM-12 was virucidal and can disrupt HCV particles. Finally we demonstrated that POM-12 had no effect on the vesicular stomatitis virus infection while had weak inhibitory activity against the influenza virus infection. In conclusion, we identified a potent anti-HCV compound which may provide an attractive drug candidate to cure HCV infection.
