The invention uses 4-bromo-2-hydroxy acetophenone as raw material, and carries out coupling reaction with 4- (diphenylamino) phenylboronic acid to obtain 4- (diphenylamino) phenyl-2-hydroxy acetophenone, and then carries out aldol condensation and cyclization reaction with furfural to obtain 6- (4- (diphenylamino) phenyl) -2- (furan-2-yl) -3-hydroxy chromone; then carrying out esterification reaction with acryloyl chloride to obtain 6- (4- (diphenylamino) phenyl) -2- (furan-2-yl) -3-hydroxy chromone acrylate. The compound can react with cysteine rapidly and exclusively at room temperature to change the fluorescent color of the solution from colorless to orange red, and the minimum detection limit is 9.76X10 ‑8 M. The probe can be used as a fluorescent probe for detecting cysteine and has good application prospect.
Description
Technical Field
The invention belongs to the technical field of fine organic synthesis, and relates to a (diphenylamino) phenyl flavonoid fluorescent probe for detecting cysteine and a preparation method thereof.
Background
Cysteine (Cys), homocysteine (Hcy) and Glutathione (GSH) are the main thiol-containing amino acids that play an important role in many biological processes. Among them, cys is directly related to a number of important cellular functions, such as antioxidant defense, cell growth, detoxification and metabolism, etc. Thus, abnormalities in Cys levels in cells are also associated with various diseases. Cys deficiency can lead to slow growth rate, reduced hematopoiesis, skin damage, hair decolorization, reduced body weight ratio, plasma albumin levels, leukopenia, liver damage, and Parkinson's disease; in contrast, excess Cys may lead to severe neurotoxicity, alzheimer's disease and cardiovascular disease. It is therefore of great importance to develop efficient methods for monitoring changes in cysteine concentration.
There are many reported methods for detecting cysteine, mainly including high performance liquid chromatography, atomic absorption spectrometry, gas chromatography, methylene blue method, electrochemical analysis and the like, but the methods have the defects of complex sample pretreatment, expensive equipment, complex operation, long detection time consumption and certain limitations. In contrast, the fluorescent probe can be used as a simple and effective Cys detection method, has the advantages of non-invasiveness, high sensitivity, high selectivity and the like, and can be imaged on living cells in real time. The organic micromolecular fluorescent probe has the characteristics of small volume, simple synthesis, quick reaction time, good selectivity, high sensitivity, convenience in real-time detection by taking fluorescence as an output signal and the like, and becomes an important method for detecting cysteine in recent years.
Disclosure of Invention
Aiming at the defects existing in the prior art, the technical problem to be solved by the invention is to provide the (diphenylamino) phenyl flavonoid fluorescent probe which meets the use requirement of cysteine detection. The invention aims to provide a preparation method of the (diphenylamino) phenyl flavonoid fluorescent probe. The invention also solves the technical problem of providing an application of the (diphenylamino) phenyl flavonoid fluorescent probe.
In order to solve the technical problems, the invention adopts the following technical scheme:
the (diphenylamino) phenyl flavonoid fluorescent probe for detecting cysteine is 6- (4- (diphenylamino) phenyl) -2- (furan-2-yl) -3-hydroxy chromone acrylate, and has the structural formula:
the preparation method of the (diphenylamino) phenyl flavonoid fluorescent probe for detecting cysteine comprises the following process steps:
1) Taking 4-bromo-2-hydroxyacetophenone as a raw material, and carrying out coupling reaction with 4- (diphenylamino) phenylboronic acid to obtain 4- (diphenylamino) phenyl-2-hydroxyacetophenone;
2) 4- (diphenylamino) phenyl-2-hydroxy acetophenone and furfural undergo condensation cyclization reaction to obtain 6- (4- (diphenylamino) phenyl) -2- (furan-2-yl) -3-hydroxy chromone;
3) Esterification reaction is carried out on 6- (4- (diphenylamino) phenyl) -2- (furan-2-yl) -3-hydroxy chromanone and acryloyl chloride, so as to obtain 6- (4- (diphenylamino) phenyl) -2- (furan-2-yl) -3-hydroxy chromanone acrylate.
In the step 1), 4-bromo-2-hydroxyacetophenone is used as a raw material and is subjected to a coupling reaction with 4- (diphenylamino) phenylboronic acid to obtain 4- (diphenylamino) phenyl-2-hydroxyacetophenone, and the specific preparation steps comprise:
(1) 10mmol of 4-bromo-2-hydroxyacetophenone, 12mmol of 4- (diphenylamino) phenylboronic acid, 40mmol of sodium carbonate and 1mmol of tetrakis (triphenylphosphine) palladium are sequentially added into a dry three-neck flask, 50mL of dioxane and 15mL of water are added to dissolve the solid, the mixture is heated to 90 ℃ under the condition of nitrogen to react overnight, and the reaction is stopped after the reaction is completed by tracking and monitoring by a TLC method;
(2) Removing dioxane and water from the reaction solution by reduced pressure distillation, adding ethyl acetate, washing with saturated saline solution to be neutral, drying an organic phase by anhydrous sodium sulfate, filtering and concentrating to obtain a crude product of 4- (diphenylamino) phenyl-2-hydroxyacetophenone;
(3) The crude 4- (diphenylamino) phenyl-2-hydroxyacetophenone product was separated by a silica gel column (ethyl acetate/petroleum ether=1/20, v/v) to give 4- (diphenylamino) phenyl-2-hydroxyacetophenone.
In the step 2), 4- (diphenylamino) phenyl-2-hydroxy acetophenone and furfural undergo condensation cyclization reaction to obtain 6- (4- (diphenylamino) phenyl) -2- (furan-2-yl) -3-hydroxy chromone, wherein the specific preparation steps comprise:
(1) Sequentially adding 5mmol of 4- (diphenylamino) phenyl-2-hydroxyacetophenone, 5mmol of furfural, 10mmol of sodium hydroxide and 50mL of ethanol into a dry three-neck flask at the temperature of 0 ℃ and reacting for 8-10 h at room temperature;
