Some new (2′–5′)triadenylates 13–16, containing at the 2′-terminal end 3′-fluoro-2′,3′-dideoxyadenosine derivatives, have been synthesized by the phosphotriester method. The selectively blocked nucleosides 2, 4, 5, and 7, were synthesized from the corresponding unprotected nucleosides 1, 3, and 6. The synthesized trimers 13, and 14 were 4- and 8-fold, respectively, more stable towards phosphodiesterase
一些新的(2'-5')triadenylates 13 - 16,含在2'-末端氟-2- 3'',3'-二脱氧腺苷衍生物,已通过磷酸三酯法合成。选择性封闭的核苷2,4,5,和7中,从相应的未保护核苷合成1,3,和6。合成的三聚体13和14分别为4倍和8倍,比来自天然三聚体17的对猪屎豆的磷酸二酯酶更稳定。与三聚体17相比新的化合物13 - 15抑制HIV-1逆转录酶(RT)活性,和15和16的HIV-1诱导的合胞体形成2-3倍,而没有的13 - 16可以提高ř核苷酸酶大号活性。
