Abstract A series of ethyl 6-bromo-8-hydroxyimidazo [1, 2-a] pyridine-3-carboxylate derivatives were synthesized and evaluated for their anti-hepatitis B virus (HBV) activity and cytotoxicity in HepG2. 2.15 cells. Nearly half of the tested compounds were proved to be highly effective in inhibiting the replication of HBV DNA with IC 50 values ranging from 1.3 to 9.1 µM. Among them, 10o and 10s were identified as the most promising compounds.
