Four self-complementary decadeoxyribonucleotides, dApTpApTpApTpApTpApT, dApTpApTpCpGpApTpApT, dApTpApTpGpCpApTpApT and dApApApApApTpTpTpTpT, were chemically synthesized by the phosphotriester procedure. Efforts were concentrated on keeping the procedure as simple as possible, concomitant with obtaining high-purity products at each step of the process. The decamers were elaborated from the 3'-end, starting
dApTpApTpApTpApTpApT,dApTpApTpCpGpApTpApT和dApApApApApApApApApTpTpTly化学合成了四个自互补的十氧杂核糖核苷酸dApTpApTpApTpApTpApT,dApTpApTpCpGpCpApTpApTply。努力集中于使过程尽可能简单,同时在该过程的每个步骤中获得高纯度的产品。根据以下方案,从3'-末端以3'- O-苯甲酰化的单体开始精加工十聚体:单体+单体二聚体+二聚体四聚体+二聚六聚体+四聚体十聚体。中间体和完全封闭的十聚体的纯度通过色谱法和300MHz 1 HN M R.光谱法进行监测。解封闭的十氧杂核糖核苷酸的特征在于它们的UV,CD和1 HNMR。光谱。
