As a signal transduction molecule in organism, H2S plays an important role in many physiological processes. In this paper, a novel H2S fluorescent probe SBD was designed based on 1,8-naphthalimide and dinitrobenzenesulfonyl group. In DMSO-PBS solution, probe SBD could recognize H2S and change the color of solution from yellow to pink, realizing the naked eye recognition for H2S. In addition, probe
作为生物体内的信号转导分子,H 2 S在许多生理过程中发挥着重要作用。本文设计了一种基于1,8-萘酰亚胺和二硝基苯磺酰基的新型H 2 S荧光探针SBD。在DMSO-PBS溶液中,探针SBD可以识别H 2 S,并将溶液颜色由黄色变为粉红色,实现了对H 2 S的肉眼识别。此外,探针SBD显示出较高的荧光增强率(45倍),选择性好,抗干扰能力强,检测限低至152 nM。最重要的是,探针SBD显示出非常低的细胞毒性,并已成功应用于活细胞中的外源H 2 S成像。
