摘要：

Ethnopharmacological relevance: The aim of this study was to determine the anti-hepatitis B effect of isochlorogenic acid A isolated from Laggera alata (Asteraceae), a traditional Chinese herbal medicine. Materials and methods: The anti-hepatitis B activity of isochlorogenic acid A was evaluated by the D-galactosamine (D-GalN)-induced HL-7702 hepatocyte damage model and the HBV-transfected HepG2.2.15 cells. Results: Isochlorogenic acid A significantly improved HL-7702 hepatocyte viability and markedly inhibited the productions of HBsAg and HBeAg. The inhibitory rates of isochlorogenic acid A on the HBsAg and HBeAg expressions were 86.9% and 72.9%, respectively. In addition, isochlorogenic acid A declined markedly the content of hepatitis B virus covalently closed circular DNA (HBV cccDNA) and induced significantly the heme oxygenase-1 (HO-1) expression in HepG2.2.15 cells. Conclusions: Isochlorogenic acid A was verified to possess the potent anti-hepatitis B activity. The anti-HBV target of isochlorogenic acid A is probably associated with blocking the translation step of the HBV replication. Overexpression of HO-1 may contribute to the anti-HBV activity of isochlorogenic acid A by reducing the stability of the HBV core protein and thus blocking the refill of nuclear HBV cccDNA. Additionally, the hepatoprotective effect of isochlorogenic acid A could be achieved by its antioxidative property and induction of HO-1. (C) 2012 Elsevier Ireland Ltd. All rights reserved.
