A series of 4-aryl-6-chloro-quinoline derivatives were synthesized and evaluated for their anti-hepatitis B virus (HBV) activities, namely the abilities to inhibit the secretion of HBV surface antigen (HBsAg), HBV e antigen (HBeAg), and replication of HBV DNA in HepG 2.2.15 cells. Most of the compounds exhibited moderate inhibitory activity against the secretion of HBsAg and HBeAg. Nine compounds (3, 5, 6, 7, 10, 14, 17, 20, 24) showed significant inhibition against HBV DNA replication with IC₅₀ values in the range of 4.4–9.8μM, which were comparative to that of positive control tenofovir. Of them, compounds 10, 17, and 20 had low cytotoxicities, resulting in high SI values, >551.2, >143.7, and >284.5, respectively.
