glycosyl moiety at the N-1 position, that have the ability to mimic the natural 2'-deoxyribosyl moiety. Some of these potential antiviral compounds included variations at both C-5 and C-6 positions of the uracil base. Other variations of the uracil derivatives were the 6-aza congeners. 4-Amino and 4-methoxy pyrimidine derivatives were also made. Compounds in which the base moiety was substituted by 5-chloro-
乙型肝炎病毒(HBV)是全世界慢性肝病的最常见原因。由于长期使用和停止治疗后病毒DNA反弹,对临床抗HBV药物拉米夫定产生的耐药性已成为当前疗法的主要挫折。我们合成了一系列嘧啶核苷,它们在C-5位具有多个取代基,在N-1位具有1-[((2-羟基-1-(羟甲基)乙氧基)甲基]柔性无环糖基部分,具有模仿天然2'-脱氧核糖基部分的能力。这些潜在的抗病毒化合物中的一些在尿嘧啶碱基的C-5和C-6位置均包含变异。尿嘧啶衍生物的其他变体是6-氮杂同源物。还制备了4-氨基和4-甲氧基嘧啶衍生物。碱基部分被5-氯-(25),5-(2-溴乙烯基)-(32)或5-溴-6-甲基-(37)基团取代的化合物对鸭HBV具有显着的活性,野生型人HBV(2.2.15个细胞)和抗拉米夫定的HBV,其中包含单突变和双突变。直至测试的最高浓度,在宿主HepG2和Vero细胞中均未见细胞毒性。与相应的嘌呤核苷更昔洛韦相比,化合物
