switching oligonucleotides. With the aim of assessing the effect of covalently linking Retro-1 to the biologically active oligonucleotide, three different derivatives of Retro-1 were prepared that incorporated a phosphoramidite group, a thiol or a 1,3-diene, respectively. Retro-1–oligonucleotide conjugates were assembled both on-resin (coupling of the phosphoramidite) and from reactions in solution (Michael-type
已描述添加小分子 Retro-1 可增强反义和剪接转换寡核苷酸。为了评估共价连接 Retro-1 与生物活性寡核苷酸的效果,制备了三种不同的 Retro-1 衍生物,它们分别掺入了亚磷酰胺基团、硫醇或 1,3-二烯。Retro-1-寡核苷酸缀合物在树脂上(亚磷酰胺的偶联)和溶液中的反应(迈克尔型硫醇 - 马来酰亚胺反应和 Diels-Alder 环加成反应)组装。用所得偶联物进行的剪接转换分析表明它们具有活性,但与众所周知的 HeLa Luc705 报告系统中未偶联的寡核苷酸相比,它们几乎没有优势。
