  Synthesis and anti-HIV-1 activity of 2'-"up"-fluoro analogs of active anti-AIDS nucleosides 3'-azido-3'-deoxythymidine (AZT) and 2',3'-dideoxycytidine (DDC)

  摘要：

  1-(3-Azido-2,3-dideoxy-2-fluoro-beta-D-arabinofuranosyl)thymine (6, F-AZT) and 1-(2,3-dideoxy-2-fluoro-beta-D-threopentofuranosyl)cytosine (12, F-DDC) were synthesized from the potent antiherpes virus nucleosides 1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)thymine (1, FMAU) and 1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)-5-iodocytosine (FIAC) in the hope that introduction of a 2-"up"-fluoro substituent might potentiate the anti-HIV activity of AZT and DDC. FMAU (1) was converted in three steps into 2,3'-anhydro-1-(2-fluoro-2-deoxy-5-O-trityl-beta-D-lyxofuranosyl)thymine (4), which when treated with NaN3 followed by detritylation afforded 6. F-DDC was prepared by two methods. Tritylation of FIAC followed by treatment of the product with thiocarbonyldimidazole afforded the 5'-O-trityl-3'-O-(imidazolyl)thiocarbonyl nucleoside 9. Upon radical reduction of 9 with Bu3SnH and AIBN, 5'-O-trityl-DDC 10 was obtained. Compound 10 was detritylated to give 12, which (when obtained by this procedure) resisted crystallization, but the diacetate 12' was obtained in crystalline form. Alternatively, FAC (14) was converted into N4,O5'-dibenzoyl derivative 15, which was treated with thiocarbonyldiimidazole. Reduction of 16 with Bu3SnH/AIBN followed by debenzoylation afforded 12, which was obtained in crystalline form. F-AZT did not exhibit any significant activity against the human immunodeficiency virus (HIV) in vitro. F-DDC, however, showed activity against HIV-1, but the therapeutic index is much inferior to that of AZT.

  3'-Fluoro-2'，3'-Dideoxy-5-chlorouridine：一系列新的2'-和3'-氟化2'，3'-Dideoxynucleoside类似物中最具选择性的抗HIV-1药物。

  摘要：

  合成了一系列的2'-和3'-氟化2'，3'-双脱氧核苷和3'-叠氮基2'，3'-双脱氧核苷，并评估了其对人免疫缺陷病毒1（HIV-1）的抑制活性在MT-4细胞中复制。将3'-氟-或3'-叠氮基-2'，3'-二脱氧腺苷转化为相应的肌苷或将2'，3'-二脱氧腺苷进行8-溴化都不会增加抗HIV-1的活性。在赤型或苏型构型中引入2'-氟也没有导致母体2'，3'-二脱氧核苷的抗HIV-1活性提高。1-（2-氟-2,3-二脱氧-β-D-苏-戊呋喃糖基）胞嘧啶和1-（2-氟-2,3-二脱氧-β-D-四氢呋喃呋喃糖基）胸腺嘧啶仅具有少量活性。但是，3'-fluoro-2'，3' -dideoxyuridine（FddUrd）被证明是有效的且是相对无毒的HIV-1抑制剂。尝试制备FddUrd的5-卤代衍生物，以进一步提高其抗HIV效能和选择性。在这些5-卤代衍生物中，3'-氟-2'，3'-二脱氧-5-氯尿苷
