Abstract
A series of novel 6-chloro-4-(2-chlorophenyl)-3-(2-hydroxyethyl) quinolin-2(1H)-one derivatives were synthesized and evaluated for anti-hepatitis B virus (anti-HBV) activities in vitro to explore their structure-activity relationships (SARs). Most of the synthesized compounds possessed potent anti-HBV activity, of which the promising compound 44 exhibited significantly inhibitory potency against the secretion of hepatitis surface antigen (HBsAg) (IC(50) = 0.010 mM, SI > 135), hepatitis e antigen (HBeAg) (IC(50) = 0.026 mM, SI > 51) and the replication of HBV DNA (IC(50) = 0.045 mM). Preliminary mechanism study suggested compound 44 could mainly enhance the transcript activity of HBV ENI (enhancer I), EN-II (enhancer II).
