A novel series of ethyl 5-hydroxy-4-substituted aminomethyl-2-sulfinylmethyl-1H-indole-3-carboxylates 8a―8j and 11e―11f was synthesized and evaluated in HepG2.2.15 cells for their anti-hepatitits B virus(HBV) acti-vity and cytotoxicity.Among them,six compounds showed more potent inhibitory activity than lamivudine.Compound 8e exhibited the most significant anti-HBV activity with an IC50 value of 1.62 μmol/L,which was 33-times more potent than the reference drug lamivudine(IC50=54.78 μmol/L).
