  摘要：

  合成了含有2'- C-支链核苷且酰胺或腈附接到一个或两个碳烷基链上的寡脱氧核苷酸。制备2'- C-修饰的核苷的亚磷酰胺，并使用自动DNA合成将其掺入寡核苷酸中。通过紫外熔解实验测量了具有互补RNA和DNA的双链体稳定性，以评估酰胺/腈功能是否可以在不存在2'-氧的情况下诱导任何双链体稳定性。在没有2'-氧的情况下，含有2'- C-修饰的寡核苷酸的双链体稳定性降低。

  The synthesis of uridine monomers containing either a 2'-deoxy-2'-C-methylcyano or ethylcyano group is described. These monomers are intended for incorporation into oligonucleotides to investigate a proposed duplex-stabilising effect exerted by 2'-tethered amide groups.

  Four functionalized 2'-deoxy-2'-alpha-C-branched nucleosides, namely, 2'-deoxy-2'-alpha-C-(carboxymethyl)-uridine, 2'-deoxy-2'-alpha-acetamidouridine, 2'-deoxy-2'-alpha-C-(hydroxyethyl)uridine, and 2'-deoxy-2'-alpha-C-(2,3-dihydroxypropyl)uridine, have been prepared. Conversion of these nucleosides to their appropriately protected phosphoramidites, followed by tetrazole-induced reaction with 2',3'-di-O-acetyluridine, oxidation, and subsequent deprotection furnished the corresponding dinucleoside monophosphates. During the oxidation of the amide-derived phosphite, partial dehydration occurred to give a mixture of the amide- and nitrile-containing dimers. Interestingly, the ratio of amide to nitrile could be largely controlled by choice of oxidant. The hydroxyethyl- and dihydroxypropyl-modified dimers were particularly resistant to snake venom phosphodiesterase-catalyzed hydrolysis (relative half-lives of 129 and 120, respectively, in comparison to UpU). It is anticipated that these nucleoside analogues will ultimately be used in the construction of ribozymes containing enhanced functionality and nuclease resistance.

  Oligodeoxynucleotides containing 2′-C-branched nucleosides with an amide or nitrile appended to either a one or two carbon alkyl chain have been synthesised. The phosphoramidites of the 2′-C-modified nucleosides were prepared and incorporated into the oligonucleotides using automated DNA synthesis. The duplex stability with complementary RNA and DNA was measured by UV melting experiments, in order
