Novel beta-L-2',3'-dideoxy-3'-fluoro nucleosides were synthesized and further converted to their 5'-triphosphates. Their inhibitory activities against hepatitis B virus (HBV) and duck hepatitis B virus (DHBV) DNA polymerases, human immunodeficiency virus (HIV) reverse transcriptase (RT), and the cellular DNA polymerases alpha, beta, gamma, delta, and epsilon were investigated and compared with those
合成了新的β-L-2',3'-二脱氧-3'-氟核苷,并进一步转化为它们的5'-三磷酸酯。研究了它们对乙型肝炎病毒(HBV)和鸭乙型肝炎病毒(DHBV)DNA聚合酶,人免疫缺陷病毒(HIV)逆转录酶(RT)以及细胞DNA聚合酶α,β,γ,δ和ε的抑制活性。并与相应的3'-氟修饰的β-d-类似物进行比较。3'-脱氧-3'-氟-β-L-胸苷(β-L-FTTP),2',3'-二脱氧-3'-氟-β-L-胞苷(β- L-FdCTP)和2',3'-二脱氧-3'-氟-β-1-5-甲基胞苷(β-L-FMetdCTP)成为HBV / DHBV DNA聚合酶的有效抑制剂(IC50 = 0.25-10.4 microM )。它们相等(FTTP)或更小(FMetdCTP,FdCTP)比其beta-d-counterparts有效。同样,β-L-胸苷的5'-三磷酸酯(β-L-TTP)被证明是这两种病毒酶的强抑制剂(IC50
