Development and Application of a Coumarin pH Fluorescent Dye
Coumarins are widely used in anti-tumor,anti-oxidation,anti-inflammatory and other pharmacological researches due to their good fluorescence spectrum characteristics. It was showed in the previous study that 3-benzimidazole-7-hydroxycoumarin could serve as a fluorescent probe to monitor intracellular pH changes(p,K,a = 7.20, pH 6.50-8.30). Herein, 3-(6-methoxy-1H-benzimidazole)-7-hydroxy coumarin(,BC,) was synthesized by introducing a methoxy electron donor group onto the C-3 benzimidazole of 3-methoxy-1H-benzimidazole. The structure of the probe compound was determined by,hydrogen nuclear magnetic resonance spectroscopy(,1,H NMR), carbon nuclear magnetic resonance spectroscopy(,13,C NMR)and high resolution mass spectrometry(HR-MS). The fluorescence properties and pH value of the probe on the detection were investigated. Results showed that the probe has high selectivity and anti-interference ability. The fluorescence intensity of the probe increases with the increase of pH value in the range of pH 5.5-10.0(p,K,a = 8.36). Furthermore, ,BC, could be successfully applied to mark pH changes in HeLa cells, showing a good prospect of biomedical applications.
