Abstract

The invention discloses a polymer-resveratrol bonded drug and a preparation method thereof. The resveratrol polymer-bonded drug has the following general formula: P-RES'm wherein: P is a water-soluble polymer, m is an integer from 1 to 50; RES' is a resveratrol derivative , the resveratrol derivative is made of resveratrol and acid chloride. The polymer bonded drug of the present invention has good hydrophilicity and biocompatibility, can avoid human reticuloendothelial system phagocytosis in the blood circulation, and ensure sufficient time to reach the tumor site through the EPR effect, and then enter the cell through endocytosis , efficient targeting of experimental drugs.

Description

Technical field [0001] The invention relates to the field of medicine technology. More specifically, it relates to a resveratrol polymer bonded drug and a preparation method thereof. Background technique [0002] Resveratrol (resveratrol), a 1,2-stilbene derivative, its chemical name is 3,4',5-trihydroxy-trans-stilbene (3,4',5 -trihydroxy-stilbene), a colorless needle-like crystal, easily soluble in organic solvents such as ether, chloroform, methanol, ethanol, acetone, and ethyl acetate. Resveratrol is a kind of plant antitoxin produced by plants. It has a variety of physiological and pharmacological effects. It is the main active ingredient in grapes. Its structural formula is: [0003] [0004] Studies so far have shown that resveratrol has anti-tumor, anti-cardiovascular disease, anti-oxidation, and anti-bacterial effects. However, resveratrol is a polyphenol compound, which has the shortcomings of poor stability and insoluble in water, which limits its application and deve...
