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
合成了一系列新型的6-氯-4-(2-氯苯基)-3-(2-羟乙基)喹啉-2(1 H)-一衍生物,并评估了其抗乙型肝炎病毒(anti-HBV)的活性。体外研究其结构-活性关系(SAR)。大多数合成的化合物都具有有效的抗HBV活性,其中有希望的化合物44对肝炎表面抗原(HBsAg)(IC 50 = 0.010 mM,SI> 135),戊型肝炎抗原(HBeAg)的分泌具有显着的抑制作用。(IC 50 = 0.026 mM,SI> 51)和HBV DNA复制(IC 50 = 0.045 mM)。初步机理研究表明化合物44 可以主要增强HBV ENI(enhancer I),EN-II(enhancer II)的转录活性。
