A photolabile o-nitrobenzyl linker–cyclooctyne conjugate was prepared, immobilized on poly(methacrylate) beads and utilized as a trap for azide-functionalized compounds. These could be released by 365 nm UV light irradiation in high yield and purity. The “reagent-free” and time economic catch and release protocol was deemed useful for chemical proteomics applications.
制备了一种光敏性邻硝基苄基连接体-环辛炔共轭物,将其固定在聚甲基丙烯酸酯珠上,并将其用作叠氮功能化化合物的捕集器。在 365 纳米紫外线照射下,这些化合物可以高产率、高纯度地释放出来。这种 "无需试剂"、时间经济的捕获和释放方案被认为可用于化学蛋白质组学应用。
