Abstract

The invention belongs to the field of medicinal chemistry, and relates to flavonoid derivatives and application thereof in preparing a medicinal composition for treating diseases related with dopamine transport protein. The flavonoid derivatives of the invention have a structure of a formula (I). A biological evaluation result shows that a compound of the invention represents better activation function on the dopamine transport protein compared with the prior art, can adjust the transport of dopamine by promoting the transport function of the dopamine transport protein, maintain extracellular dopamine concentration balance, and can be prepared into dopamine transport protein agonist used for treating mental diseases and neurological diseases. R1 is selected from hydroxy, alkoxyl of C1 to C8, ester group of C1 to C8, glucoside and halogen; R2 is selected from hydrogen, C7-hydroxy, C7-alkoxyl, C7-ester and C7-halogen respectively; and R3 is selected from the hydrogen respectively, or contain one or a plurality of substituent groups on a benzene ring, wherein the substituent groups are selected from the hydroxy, alkoxyl, ester group, aryl (heteroaryl), the hydrogen and glycoside group respectively.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and relates to flavonoid derivatives and their application in the preparation of pharmaceutical compositions, especially the application in the preparation of dopamine transport protein agonists. Background technique [0002] Mental and neurological disorders seriously affect the health of millions of people around the world. It has been reported that some common mental and / or neurological diseases such as anxiety disorders, mood disorders, schizophrenia, personality disorders, psychosexual disorders , drug abuse and dependence (drug abuse and dependence) affect people of all ages, and the duration of these diseases varies from weeks to decades. [0003] Studies have found that important neurotransmitters such as dopamine (DA), norepinephrine (norepinephrine), and serotonin (serotonin) play key physiological roles in mental and neurological diseases. Dopamine is the main catecholamine neurotr...
