Hepatitis B virus (HBV) infections are a major global health problem despite the availability of an effective vaccine. Over two billion people are infected at present and about 400 million are chronically infected carriers of this virus. Paeonol, 2-hydroxy-4-methoxy acetophenone, a major composition of the traditional Chinese medicine, peony, that are being used for more than thousand years. Paeonol exhibit many interesting biological activities that has been applied to anti-inflammatory, analgesic effects, antioxidant, anti-diabetic, and acaricidal activity. Herein, we report a new series of paeonol derivatives has been tested for their design, synthesis, and bioevaluation. The paeonol core was keept and a new sulfone side chain was conjugated in the phenol group. These new serious of paeonol derivatives were found to have potential anti-HBV effects in HepG2 2.2.15 cells. Among them, compound XX had the most potent inhibition activity of the IC50 value of 16.38 g/mL with high selectivity index, SI (TC50/IC50) 10.64. The newly synthesized compounds can be a structural template for designing and developing novel anti-HBV agents.
