We report syntheses of new amide-linked (di-penta)nucleoside analogues of antisense oligonucleotide components. Solution-phase coupling of 3'-(carboxymethyl)-3'-deoxy- and 5'-amino-5'-deoxynucleoside derivatives provides amide dimers. Activated [3'-(carboxymethyl)-3'-deoxy] units with a 5'-azido-5'-deoxy function provide "masked" 5'-amino-5'-deoxy residues for chain extension, and a 5'-O-DMT-protected
我们报告了反义寡核苷酸组件的新的酰胺连接的(二戊)核苷类似物的合成。3'-(羧甲基)-3'-脱氧-和5'-氨基-5'-脱氧核苷衍生物的溶液相偶联提供了酰胺二聚体。具有5'-叠氮基-5'-脱氧功能的活化的[3'-(羧甲基)-3'-脱氧]单元提供“被屏蔽的” 5'-氨基-5'-脱氧残基用于链延伸,以及5'- O-DMT保护的单元提供了5'末端以连接至磷酸二酯键。
