needed to combat hepatitis B virus (HBV) infection due to drug-resistant virus. In this paper, a series of novel 4-monosubstituted 2′-deoxy-2′-β-fluoro-4′-azido-β-d-arabinofuranosyl 1,2,3-triazole nucleoside analogues (1a-g) were designed, synthesized and screened for in vitro anti-HBV activity. At 5.0 μM in the cellular model, all the synthetic compounds display activities comparable to that of the
由于抗药性病毒,迫切需要新型药物来对抗乙型肝炎病毒(HBV)感染。本文设计了一系列新颖的4-单取代的2'-脱氧-2'-β-氟-4'-叠氮基-β- d-阿拉伯呋喃糖基1,2,3-三唑核苷类似物(1a-g),合成并筛选体外抗HBV活性。在5.0 μ M在蜂窝模式下,所有的合成化合物显示比得上阳性对照,拉米夫定在20活动 μ M的化合物测试,酰胺-取代的类似物(1A)在细胞模型中显示出最有希望的抗HBV活性和低细胞毒性。特别是,它对抗拉米夫定的HBV突变体具有出色的活性。在鸭HBV(DHBV)感染的鸭模型中,用1a处理可显着降低血清和肝脏DHBV DNA水平(分别为67.4%和53.3%)。HBV聚合物/ 1a-三磷酸酯(1a-TP)配合物的结构分析表明,1a-TP通过与4-氨基-1,2,3-三唑和4-氨基苯甲酸产生的酶残基的特异性范德华相互作用而稳定。 '-叠氮基团。
