Abstract
A flavonoid molecule that showed a unique anti-HBV function was isolated from Phyllanthus urinaria. The molecular formula was determined as C14H6O8 based on FAM-MS analysis and the structure was determined by NMR. The identified flavonoid molecule, ellagic acid, showed unique anti-HBV functions. Ellagic acid did not inhibit either HBV polymerase activity, HBV replication or block HBsAg secretion. Rather, ellagic acid blocks effectively HBeAg secretion in HepG2 2.2.15 cells (IC50 = 0.07 μg/ml). Since HBeAg is involved in immune tolerance during HBV infection, ellagic acid, a newly identified functional anti-HBV compound, may be a new candidate therapeutic against immune tolerance in HBV-infected individuals.
