Abstract

The invention discloses an 8-aminoquinoline amide derivative, a preparation method, application and a fluorescence analysis method thereof. The preparation method of the 8-aminoquinoline amide derivative comprises the following steps that (1a) N-bromoacetyl-8-aminoquinoline, propargylamine and acetonitrile are weighed, the N-bromoacetyl-8-aminoquinoline, propargylamine and the acetonitrile are dissolved in the acetonitrile, and then potassium carbonate is added to obtain a reaction mixture; (2a) the reaction mixture obtained in the step (1a) is subjected to stirring reaction at room temperature, filtration is performed, a solvent is removed, and then the 8-aminoquinoline amide derivative is obtained through column chromatography elution. The 8-aminoquinoline amide derivative can be appliedto the field of fluorescent probes. Zn<2+> and Cd<2+> can be simultaneously detected through the derivative, the preparation method, application and the fluorescent analysis method performed based onthe derivative.

Description

technical field [0001] The invention relates to a derivative, a preparation method, an application, and a method for performing fluorescence analysis based on the derivative, in particular to an 8-aminoquinoline amide derivative, a preparation method, an application, and a method for fluorescence analysis thereof. Background technique [0002] Metals in organisms generally exist in the form of ions, and they play a very important role in various physiological and pathological processes of organisms. Zinc ions (Zn 2+ ) has a high content in nature and is the second most essential element for the human body. It is known as the "flower of life" for the human body. The right amount of Zn in the human body 2+ It can help wounds heal, promote the growth of babies, and maintain the normal functions of taste and smell. Lack of Zn 2+ It can lead to many diseases such as slow development and mental retardation, immune and reproductive function decline; Zn 2+ Excessive intake can ...
