Some new ethyl 8‐imidazolylmethyl‐7‐hydroxyquinoline‐3‐carboxylate derivatives have been synthesized and evaluated for their anti‐hepatitis B virus (HBV) activities and cytotoxicities in HepG2.2.15 cells stable transfection with HBV. Compounds 13a, 11b, 11c, 12c, 13c, 11g, and 12g inhibited the expression of the viral antigens HBsAg or HBeAg in a low concentration, of which 11c (IC50 = 12.6 μM, SI
已经合成了一些新的 8-咪唑基甲基-7-羟基喹啉-3-羧酸乙酯衍生物,并评估了它们在稳定转染 HBV 的 HepG2.2.15 细胞中的抗乙型肝炎病毒 (HBV) 活性和细胞毒性。化合物13a、11b、11c、12c、13c、11g和12g在低浓度下抑制病毒抗原HBsAg或HBeAg的表达,其中11c (IC50 = 12.6 μM, SI = 12.4), 12c (IC50 = 12.5) , SI = 37.9) 和 12g (IC50 = 2.6 μM, SI = 61.6) 显示出比阳性对照拉米夫定更有效的抑制 HBV DNA 复制的能力 (3TC, IC50 = 343.2 μM, SI = 7.0)。
