Abstract

The invention discloses application of a polyhydroxy bromo-benzophenone compound and derivatives of the polyhydroxy bromo-benzophenone compound in treatment and prevention of atherosclerosis, and belongs to the technical field of medicines. According to the application of the polyhydroxy bromo-benzophenone compound in the treatment and the prevention of the atherosclerosis, an active ingredient is the polyhydroxy bromo-benzophenone compound 2,4',5'-trihydroxy-5,2'-dibromo-benzophenone, and according to the application of the derivatives of the polyhydroxy bromo-benzophenone compound in the treatment and the prevention of the atherosclerosis, active ingredients are medicinal salt, medicinal ester and medicinal ether of the 2,4',5'-trihydroxy-5,2'-dibromo-benzophenone. Due to the fact that the expression of triglyceride (TG) and low density lipoprotein-cholesterol (LDL-C) in blood serum is reduced, and the expression of inflammatory factors including interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) and adhesion molecules sICAM-1 in the blood serum is restrained, vascular endothelial injuries are restrained, and vascular endothelia are protected, so that occurrence and development of the atherosclerosis (AS) are restrained, and more broad prospects are opened up for clinical medication.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to the pharmaceutical application of polyhydroxy brominated benzophenone compounds in the treatment and prevention of cardiovascular and cerebrovascular diseases, in particular to the application of polyhydroxy brominated benzophenone compounds and their derivatives in the treatment and prevention of cardiovascular and cerebrovascular diseases. Use in prevention of atherosclerosis. Background technique [0002] Atherosclerosis (AS) is a generalized arterial lesion characterized by subintimal lipid deposition, smooth muscle cell and collagen proliferation, and foam cell formation. Thrombosis can lead to ischemic cardiovascular and cerebrovascular diseases and peripheral arterial diseases, which seriously threaten human life and health. [0003] The occurrence and development of AS is the result of the joint action of many factors. There are many theories about its pathogenesis, inclu...
