Preparation of the three hexadecanucleotides, dGpTpApTpCpApCpGpApGpGpCpCpCpTpT, dCpGpApCpGpApGpCpGpTpGpApCpApCpC and cTpGpCpCpGpGpCpCpApCpGpApTpGpCpG, is described by a rapid and simple solid-phase method on polyacrylamide supports. The synthesis were performed by the extension of the method described in the previous paper using di and trinucleotides of defined sequences as an incoming 3'-phosphodiester unit. Although the coupling yields to form phosphotriester bonds are slightly lower than those for the homothymidylic acid series, pure polydeoxyribonucleotides of defined sequences can be synthesized without any major difficulty.
三种十六聚核苷酸dGpTpApTpCpApCpGpApGpGpCpCpCpTpT、dCpGpApCpGpApGpCpGpTpGpApCpApCpC和cTpGpCpCpGpGpCpCpApCpGpApTpGpCpG的制备方法,采用了在聚丙烯酰胺载体上快速简便的固相法进行描述。合成是通过扩展前一篇论文中描述的方法来完成的,使用特定序列的二核苷酸和三核苷酸作为引入的3'-磷酸二酯单元。尽管形成磷酸三酯键的偶联产率略低于同胸腺嘧啶酸系列,但可以毫无重大困难地合成特定序列的纯聚脱氧核糖核苷酸。
