Proline-substituted coumarin compounds were prepared and used as environment-sensitive fluorescence probes. Phosphorylation and dephosphorylation of tyrosine derivatives labeled with the coumarin–proline conjugate induced marked changes in fluorescence intensity allowing phosphatase activity to be monitored.
制备了脯氨酸取代的香豆素化合物并将其用作环境敏感的荧光探针。用香豆素-脯氨酸缀合物标记的酪氨酸衍生物的磷酸化和去磷酸化引起荧光强度的显着变化,从而可以监测磷酸酶活性。
