that carboxylic acids including natural products, drugs and fluorescent probes, as well as phosphoric acids and alcohols, are released in a controllable manner. In addition, a water-soluble leaving group based on the p-methoxycarbonylbenzyl moiety is proposed as an electrocleavable linker. We envision that this on-demand C–O cleavage will provide unique opportunities in biological research and therapeutics
为了优化药物治疗,生物活性分子的精确释放是非常需要的。有机电化学为使用电子作为无痕试剂选择性裂解化学键提供了一种高度通用的工具。我们在此提出了一种电触发反应,该反应可以在模拟的生理 pH 条件下响应电而特异性地切割 C-O 键。使用这种策略,我们展示了包括天然产物、药物和荧光探针在内的羧酸,以及磷酸和醇,以可控的方式释放。此外,基于p的水溶性离去基团-甲氧基羰基苄基部分被提议作为可电裂解的接头。我们设想这种按需的 C-O 裂解将为生物学研究和治疗提供独特的机会。
