Problems solved by technology

[0009] Both of the above two drugs can inhibit the proliferation of smooth muscle cells, endothelial cells, fibroblasts, etc.; however, these two drugs still cannot fully meet the above-mentioned needs for preventing restenosis of blood vessels in the lesion after stent implantation, especially for intravascular The inhibition of different types of cell proliferation is not selective, that is, these two drugs have a strong inhibitory effect on smooth muscle cells, but also have a strong inhibitory effect on endothelial cells. The risk of thrombosis, leading to the need for patients to continue to take antithrombotic and platelet drugs for a long time after stent implantation

Abstract

The invention discloses a class of compounds with the structure of formula X or pharmaceutically acceptable salts thereof and their preparation methods and uses: wherein R1 is a chemical structure containing at least one five-membered ring or one six-membered ring; R2 is a compound with a molecular weight greater than 100 And contains the chemical structure of the electron-withdrawing group.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a compound that can be used for a drug stent and its preparation method and application. Background technique [0002] The intima of blood vessels is mainly composed of endothelial cells, and the media is mainly composed of smooth muscle cells and fibroblasts. After stent implantation, in order to prevent the restenosis of blood vessels in the lesion, it is hoped to inhibit the proliferation of smooth muscle cells to the lumen of the blood vessel to a relatively large extent; but in order to prevent the occurrence of thrombus, it is hoped that the lesion can be endothelialized as soon as possible, so it is not desirable The drug inhibits endothelial cells too strongly. [0003] At present, in clinical practice, drug stents are usually used to fight vascular restenosis, which requires that the drugs carried on the drug stents have less cytotoxicity, have good fat solubility, and...
