Synthesis and anti-hepatitis B virus evaluation of novel ethyl 6-hydroxyquinoline-3-carboxylates in vitro

Add time:08/03/2019    Source:sciencedirect.com

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, 9f3, 12b6, 12f6, 13b2, 13b6, and 13f6, displayed excellent intracellular inhibitory activity and selectivity towards the replication of HBV DNA. Of these six initial hits, compound 13b6 was the most active.
