Abstract

The invention provides ferulic acid derivatives adopting a structure shown in formula I or formula II. Starting from the mechanism of various mechanisms causing brain injury after cerebral stroke and the action of ferulic acid in treatment of the cerebral stroke, alkane is taken as a joint arm, ADT-OH (5-(4-hydroxyphenyl)-3H-1,2-dithiole-3-thione) and ferulic acid are connected through ether linkage and ester linkage, and the ferulic acid derivatives are obtained. The invention further provides the application of the ferulic acid derivatives in preparation of drugs for preventing and / or treating cerebral stroke diseases.

Description

technical field [0001] The invention relates to the technical field of medicines, in particular to a ferulic acid derivative, a preparation and its application, in particular to the application of a ferulic acid derivative in medicines for the prevention and / or treatment of stroke diseases. Background technique [0002] "Stroke" (cerebralstroke) is also known as "stroke" and "cerebrovascular accident" (cerebralvascularaccident, CVA). It is an acute cerebrovascular disease, which is a group of diseases that cause brain tissue damage due to sudden rupture of blood vessels in the brain or blockage of blood vessels that prevent blood from flowing into the brain. [0003] Worldwide, stroke is the third leading cause of death and the leading cause of disability in adults. According to statistics, 500,000 to 750,000 people in the United States develop the disease every year. In China, the incidence of cerebral apoplexy reaches 2.5 million / year, and the death toll reaches 1.6 mill...
