Self-immolative dendrimers are a unique class of molecules that are able to disassemble upon undergoing a specific triggering reaction through domino-like fragmentations. We have designed and synthesized a novel AB(6) self-immolative dendritic adaptor that amplifies a single cleavage event into the release of six reporter units. The disassembly mechanism is based on a specifically triggered cleavage
自消散的树枝状大分子是一类独特的分子,能够通过类似多米诺骨牌的片段发生特定的触发反应而分解。我们已经设计和合成了一种新型的AB(6)自消灭性树突状衔接子,该衔接子将单个切割事件放大为六个报告单元的释放。拆卸机制基于特定触发的裂解事件,然后消除环状脲衍生物和连续六个六次醌甲基化物消除。通过化学或酶促引发在有机和水性条件下都可将系统拆解。将各种报告分子和触发基团引入到树突状衔接子上,以获得具有增强的特性的传感器分子,用于诊断和成像。
