The invention discloses a novel compound capable of distinguishing cysteine/homocysteine and glutathione, specifically relates to a preparation method and application of a novel fluorescent probe, and belongs to the technical field of chemical analysis and detection. Its molecular structural formula is as follows: The fluorescent probe is used for fluorescent sensing analysis of cysteine, homocysteine and glutathione in environmental or biological samples, and can be well distinguished by the difference in the output signal after interacting with the probe molecule Cysteine/homocysteine and glutathione, with good selectivity and strong anti-interference ability, can sensitively and quickly distinguish cysteine, homocysteine and glutathione from various amino acids Peptides have good application prospects. |
