Reported herein is a triple-functional H2S delivery system, which is triggered by the bioorthogonal click-and-release reaction between a newly designed diphenylamino-substituted 1,3-dithiolium-4-olate (DTO) and a strained alkyne. This COS-based H2S release platform can realize in-mitochondria H2S release in a controllable manner, and provide a concomitant fluorescence for spatiotemporal feedback of
本文报道了一种三功能 H 2 S 递送系统,该系统由新设计的二苯基氨基取代的 1,3-dithiolium-4-olate (DTO) 和应变炔烃之间的生物正交点击和释放反应触发。这种基于COS的H 2 S释放平台可以实现线粒体内H 2 S的可控释放,并为细胞内外源H 2 S的时空反馈提供伴随的荧光。
