A series of ethyl 6-bromo-5-hydroxy-1H-indole-3-carboxylates, 8a-11v, were synthesized and evaluated for their anti-hepatitis B virus (HBV) activities in 2.2.15 cells. The selective indexes of inhibition on replication of HBV DNA of compounds 11s (>8.7) and 11t (10.8), which were introduced halogen on the phenyl ring at position 2, were greater than those of the other evaluated compounds including
合成了一系列6-溴-5-羟基-1H-吲哚-3-羧酸乙酯8a-11v,并评估了它们在2.2.15细胞中的抗乙型肝炎病毒(HBV)活性。在位置2的苯环上引入卤素的化合物11s(> 8.7)和11t(10.8)对HBV DNA复制的抑制选择性指数大于包括拉米夫定(7.0)在内的其他评估化合物。化合物9e,9h,9l和11v表现出显着的抗HBV活性,这些化合物复制HBV DNA的IC(50)值分别为3.6、6.37、5.2和5.4 microg / ml,远高于这些。比阳性对照拉米夫定的效价228微克/毫升。
