coumarin and benzothiazole moieties for detecting SO2 derivatives (HSO3−/SO32−) in a ratiometric fluorescence manner. Probe CBT exhibited desirable properties such as a high specificity, a rapid response, good water solubility and a low detection limit. The Michael addition reaction was proved to be the sensing mechanism of CBT. Moreover, fluorescence imaging of cells indicated that probe CBT with low
在这项研究中,我们报告的荧光探针(CBT基于香豆素和苯并噻唑基部分,用于检测SO)2衍生物(HSO 3 - / SO 3 2-)在一个比率荧光方式。探针CBT表现出所需的特性,例如高特异性,快速响应,良好的水溶性和低检测限。迈克尔加成反应被证明是CBT的传感机制。此外,细胞的荧光成像表明具有低细胞毒性的探针CBT可用于监测内源性SO 2在病理性肝细胞(HepG2)中存在衍生物,而在正常肝细胞(L-02)中则没有,这表明探针CBT可以用于区分两种细胞。荧光共定位研究证明,该探针显示出优异的线粒体靶向活性。因此,探针CBT在探索SO 2衍生物在生物学中的作用方面具有巨大的潜力。
