Core Tip
Core tip: An infection by hepatitis C virus (HCV) causes chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. While the combination of pegylated α-interferon and ribavirin is used for the elimination of HCV, a new anti-HCV drug is required due to the poor efficacy and serious side-effects associated with this combination therapy. We searched for new anti-HCV agents from natural products and then identified oligomeric proanthocyanidin from blueberry leaves. Further investigations suggested that several heterogeneous nuclear ribonucleoproteins may be the candidate proteins involved in the proanthocyanidin-mediated inhibition of HCV subgenomic expression. Oligomeric proanthocyanidin isolated from blueberry leaves may have potential usefulness as an anti-HCV compound.
