2-amino-6-vinylpurine motif has been synthesized. The triplex-forming oligodeoxynucleotide incorporating 2 has achieved strand- and cytidine-selective cross-linking reaction to the G-C target site mediated by triple helix formation. It has been suggested that 2 reacts with a flipping cytidine at the target site.
合成了一种新的核苷衍生物(2),其在糖部分和2-氨基-6-乙烯基嘌呤基序之间具有丁基间隔基。掺入2的三链体形成寡聚脱氧核苷酸已实现了由三链螺旋形成介导的链和胞苷选择性交联反应至GC目标位点。已经提出2在靶位点与倒胞苷反应。
