Three sulfonyl benzothiazole-based fluorescent probes (RSHP1, RSHP2, and RSHP3) for the detection of biothiols (cysteine, homocysteine, and glutathione) are developed based on thiol-mediated nucleophilic aromatic substitutions. The probes exhibited good selectivity and sensitivity toward biothiols over other analytes. The probes were successfully applied for visualizing endogenous thiols in living cells.
基于硫醇介导的亲核芳香取代反应,我们开发了三种苯并噻唑磺酰基荧光探针(RSHP1、RSHP2和RSHP3),用于检测生物硫醇(半胱氨酸、高半胱氨酸和谷胱甘肽)。这些探针对生物硫醇表现出良好的选择性和灵敏度,优于其他分析物。它们成功应用于活细胞内源硫醇的可视化。
