Bifunctional linkers are provided that comprise a photocleavable moiety flanked by two different amine reactive moieties. In some embodiments the photocleavable moiety is a dimethoxynitrobenzyl moiety. In other embodiments the photocleavable moiety is 8-bromo-7-hydroxyquinoline. In other embodiments the photocleavable moiety is nitrodibenzofuran. In other embodiments the photocleavable moiety is 6-bromo-7-hydroxycoumarin-4-ylmethyl. The linkers find use in synthetic methods, including the generation of photocleavable oligonucleotides, e.g. caged morpholinos.
提供了含有光解离基团的双功能连接剂,该基团被两种不同的胺反应基团所包围。在某些实施例中,光解离基团是二甲氧基
硝基苯基基团。在其他实施例中,光解离基团是
8-溴-7-羟基喹啉。在其他实施例中,光解离基团是硝基二苯
呋喃。在其他实施例中,光解离基团是6-
溴-7-羟基
香豆素-4-基甲基。这些连接剂在合成方法中发挥作用,包括生成光解离寡核苷酸,例如被光遮蔽的吗啉寡核苷酸。
