Abstract: Objective To design and synthesize the new 2-pyridyl ketone amide derivatives and test the antiviral activity. Methods According to the pharmacophore model, a new class of 2-pyridyl ketone amide derivatives was designed, which were synthesized by Heck reaction, selective nitration reaction, catalytic hydrogenation reaction, acylation reaction and the open-loop rearrangement reaction. All the synthesized compounds were confirmed by 1H NMR, and their anti-HBV-DNA replication activity were determined. Results The designed novel 2-pyridyl ketone amide derivatives had inhibitory activity against HBV-DNA replication. Among them, compounds 6h、6e and 6a showed the best inhibitory activity. Conclusion When the 4-ethoxyl phenyl group was attached on the N atom of the benzyl ring, the compounds revealed good inhibitory activity.-
