硫化氢(H2S)和多硫化氢(H2Sn,n > 1)是许多生理过程的内源性调节剂。为了更好地理解H2S和H2Sn之间的共生关系和细胞串扰,非常需要开发能够在H2S和H2Sn之间进行双通道区分的单荧光探针。在此,我们报告了第一个双检测荧光探针DDP-1的合理设计,合成和评估,可以显示H2S和H2Sn具有不同的荧光信号。该探针在水介质和细胞中对H2S和H2Sn具有高的选择性和灵敏度。发现了第一个可以显示具有不同发射通道的H2S和H2Sn的单一荧光探针DDP-1。H2S可以通过在蓝色和绿色通道中同时出现两个荧光信号来识别,而H2Sn可以通过在绿色通道中的单一发射来识别
Hydrogen sulfide (H2S) and hydrogen polysulfides (H2Sn, n > 1) are endogenous regulators of many physiological processes. In order to better understand the symbiotic relationship and cellular cross-talk between H2S and H2Sn, it is highly desirable to develop single fluorescent probes which enable dual-channel discrimination between H2S and H2Sn. Herein we report the rational design, synthesis, and evaluation of the first dual-detection fluorescent probe DDP-1 that can visualize H2S and H2Sn with different fluorescence signals. The probe showed high selectivity and sensitivity to H2S and H2Sn in aqueous media and in cells. The first single fluorescent probe DDP-1 that can visualize H2S and H2Sn with different emission channels was discovered. H2S can be identified by the simultaneous appearance of two fluorescence signals in blue and green channels, whereas H2Sn can be characterized by the single emission in green channel
