Novel anti-hepatitis B virus-active catechin and epicatechin from Rhus tripartita.

ABSTRACT: Bioactive natural or phytoproducts have emerged as a potential source of antiviral agents. Of the Rhus spp., R. coriaria and R. succedanea have been reported for their antiviral activities against hepatitis B virus (HBV), while the anti-HBV efficacy of R. tripartita has remained elusive. In the present study, the anti-HBV activities of R. tripartita-derived novel catechin [3,5,13,14-flavantetrol-catechin or rhuspartin (RPT)] and epicatechin-3-O-rhamnoside (ECR), were assessed using the HBV-reporter cell line HepG2.2.15. RPT and ECR proved to efficiently inhibit HBV surface antigen (HBsAg) synthesis by 68.8 and 71.3%, respectively, and HBV pre-core antigen (HBeAg) production by 62.3 and 71.2%, respectively, after 5 days of treatment. Of note, RPT ha
