A reaction based fluorescence turn-on strategy for hydrogen sulfide (H(2)S) was developed. This strategy was based on a H(2)S-specific Michael addition-cyclization sequence. Other biological thiols such as cysteine and glutathione did not pursue the reaction and therefore did not turn on the fluorescence/consume the substrates. The probes showed good selectivity and sensitivity for hydrogen sulfide.
开发了一种基于反应的荧光开启策略用于检测硫化氢(H2S)。该策略基于 H2S 特异性的迈克尔加成-环化序列。其他生物硫醇,如半胱氨酸和谷胱甘肽,不会进行该反应,因此不会开启荧光/消耗底物。探针对硫化氢具有良好的选择性和灵敏度。
