Abstract

The invention relates to a colorimetric fluorescence probe for high selectivity multiple biological thiol and a preparation method thereof, particularly to the colorimetric fluorescence probe which uses selenazole ring as an identification receptor, takes an anthraquinone derivant as an information report functional group, can high selectively distinguish and identify cysteine, homocysteine and glutathione and the preparation method thereof, belonging to the technical field of life science. The colorimetric fluorescence probe has the following structure formula as shown in the specification. The colorimetric fluorescence probe is prepared by grinding and reacting a diamine compound corresponding to the colorimetric fluorescence probe for the high selectivity multiple biological thiol and selenium dioxide in an agate mortar for 15-90 min at the grinding temperature of 10-35 DEG C, the mole ratio of the corresponding diamine compound to the selenium dioxide is 1:1-5, and the reaction formula is shown in the specification. The invention can directly distinguish and identify the cysteine, the homocysteine and the glutathione by eyes, and carry out imaging analysis on biological thiol in living cells. The invention has the advantages of simple method, environmental protection and industrial production.

Description

technical field [0001] The invention relates to a highly selective multi-component biothiol colorimetric fluorescent probe and a preparation method thereof, in particular to a class of highly selective region-specific probes that use selenazole rings as recognition receptors and anthraquinone derivatives as information reporting functional groups. A colorimetric fluorescent probe for distinguishing and recognizing cysteine, homocysteine ​​and glutathione and a preparation method thereof belong to the technical field of life sciences. Background technique [0002] Thiols are a very important class of substances in life systems and chemical sciences. Small molecule thiols are widely distributed in cells, plasma and tissues, and play an extremely important role in participating in important physiological activities and maintaining redox balance in organisms. Glutathione (GSH) is the most abundant small molecule thiol compound (1-10mM) in cells, which can combine with toxic com...
