  通过与四烷基锡试剂交叉偶联获得的C-烷基化嘌呤核苷的抗病毒活性。

  摘要：

  通过将四烷基锡与卤代嘌呤核苷进行钯催化的交叉偶联，可合成2-，6-和8-烷基化（甲基，乙基和乙烯基）的腺苷类似物。8-取代类似物的合成使用瞬态保护程序完成。6烷基化的9-β-D-呋喃呋喃糖基嘌呤以及2-乙基腺苷在相对较低的浓度（0.8-10微克/ mL）下具有细胞毒性。8-甲基腺苷是牛痘病毒的有效和选择性抑制剂，而8-乙基和8-乙烯基腺苷对呼吸道合胞病毒具有特异性抑制作用。8-Vinyladenosine显示出对单纯疱疹病毒（1型）的特殊活性。

  A one step synthesis of the 8-methyl-, 8-ethyl -and 8-vinyl derivatives of adenosine, 2′-deoxyadenosine and 2′,3′-dideoxyadenosine starting from the readily available 8-bromo congeners is described. This reaction makes use of a transient silylation procedure and a Pd(0) catalysed cross-coupling with tetraorganotin reagents.

  Palladium-catalyzed cross-coupling of 8-bromo-2'-deoxyadenosine with terminal alkynes in the presence of copper(I) iodide in dimethylformamide resulted in a series of 8-(1-alkyn-1-yl)-2'-deoxyadenosines. Hydrogenation of alkynyl derivatives over 10 % Pd/C under atmospheric pressure gave 8-n-alkyl analogues in nearly quantitative yields. On partial saturation of heptynyl, pentynyl, and propynyl derivatives over Lindlar catalyst, the corresponding cis-olefins were obtained along with minor amounts of trans isomers. Of the analogues tested, the following showed some activity, i.e. they were found to be active at concentrations that were at least 3-fold lower than the cytotoxic concentrations: the 8-heptynyl derivative against vaccinia virus (VV), vesicular stomatitis virus (VSV), cytomegalovirus (CMV), and respiratory syncytial virus (RSV); the 8-propyl derivative against varicella-zoster virus (VZV) and CMV; the 8-pentyl derivative against CMV; the 8-heptyl derivative against VV, CMV, RSV, and influenza A; slid the 8-heptenyl derivative against VV, RSV, and influenza A. The unsubstituted 2'-deoxyadenosine did not show any antiviral effect, except against RSV. Except for 8-propyl-dA, the antivirally active dA analogues were rather inhibitory to the growth of human embryonic lung cells. The most cytotoxic was the 8-ethynyl derivative.

  2-, 6-, And 8-alkylated (methyl, ethyl, and vinyl) adenosine analogues were synthesized by a palladium-catalyzed cross-coupling of a tetraalkyltin with the halogenated purine nucleosides. The synthesis of the 8-substituted analogues was accomplished using a transient protection procedure. The 6-alkylated-9-beta-D-ribofuranosylpurines as well as 2-ethyladenosine were cytotoxic at relatively low concentrations
