Problems solved by technology

[0013] This preparation method uses highly toxic substances such as sodium cyanide (NaCN) or potassium cyanide (KCN) to carry out nitrilation reaction when introducing cyano groups on the ethylene unit of resveratrol. Although its reaction effect is better, the reaction needs to be carried out. 2 hours or more, the time of exposure to cyanide is longer, which causes inconvenience in the operation during the experiment and is very harmful to the health of the operators; moreover, it is very difficult to dispose of the "three wastes" after the experiment is completed, and improper disposal will seriously cause environmental pollution; in addition The management of reagents such as sodium cyanide or potassium cyanide is very strict, the purchase channel is narrow, the application is limited, and it is not suitable for industrial production

Abstract

The invention provides a cyano-containing resveratrol analogue and a preparation method and application thereof, and relates to the field of medical compounds. A structure of the cyano-containing resveratrol analogue is shown in the formula of the description; 3,5-dihydroxy-benzoic acid is mainly used as a raw material, and the cyano-containing resveratrol analogue is prepared by the following steps of methylation, reduction, brominating, Abozove rearrangement, Wittig-Hornor reaction and Knoevenegal reaction; in the preparation process of the cyano-containing resveratrol analogue, the chemical substances with lower toxicity, such as trimethylsilyl cyanide and tetrabutylammonium fluoride, are used for replacing chemicals with higher toxicity, such as sodium cyanide or potassium cyanide, to introduce cyano, so that the damage to the health of an operator is greatly decreased, and the serious harm to environments is avoided. The preparation method has the advantages that the yield is higher, the environment-friendly effect is good, and multiple types of cyano-containing resveratrol analogue with anti-cancer activity on cells can be obtained.

Description

Technical field [0001] The present invention relates to the field of medicinal compounds, in particular to cyano-containing resveratrol analogues and preparation methods and uses thereof. Background technique [0002] Resveratrol is a kind of natural polyphenols with strong biological properties mainly derived from grapes (red wine), knotweed, peanuts, mulberries and other plants, also known as stilbene. It is a chemopreventive agent for tumors, as well as a chemopreventive agent for reducing platelet aggregation, preventing and treating atherosclerosis and cardiovascular and cerebrovascular diseases. The chemical name of resveratrol is (E)-3,5,4-trihydroxystilbene, and its chemical structure is shown in structural formula 1: [0003] [0004] Resveratrol [0005] Structural formula 1 [0006] In 1993, Jayafilake and other studies showed that resveratrol has anti-cancer activity because they can inhibit the activity of protein-tyrosine kinases. Resveratrol has anti-cancer activity ...
