Photocleavable linker methods and compositions

摘要

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.
