A series of non-nucleoside ethyl 6-hydroxyquinoline-3-carboxylate derivatives were prepared and evaluated in HepG2.2.15 cells. Most compounds inhibited the expression of viral antigens HBsAg or HBeAg at low concentration. Six compounds, 9f(3), 12b(6), 12f(6), 13b(2), 13b(6), and 13f(6), displayed excellent intracellular inhibitory activity and selectivity towards the replication of HBV DNA. Of these
