Abstract

The invention discloses a substituted arone derivate, an aryloxy-phenoxy, and a carboxylic acids compound formed by the derivates of the aryloxy-phenoxy. The compound shows a good effect in pharmacological research, can reduce cholesterol, low-density lipoprotein and triglyceride in the blood at the same time, and has obvious advantages on efficacy. The conventional p-hydroxyacetophenone or aryloxy-phenoxy compound has no capacity of reducing the three components at the same time and nearly plays no effect to the p-hydroxyacetophenone and triglyceride; and the aryloxy-phenoxy compound does not work well with respect to the cholesterol and the low-density lipoprotein. The compound with a dosage of 80mg / kg has the capacity of reducing the cholesterol and the low-density lipoprotein similar to the capacity of the p-hydroxyacetophenone with the dosage of 150mg / kg.

Description

technical field [0001] The present invention relates to a novel carboxylic acid derivative compound and its preparation method and application, in particular to a carboxylic acid derivative compound composed of substituted aryl ketone derivatives, phenoxyaromatic acid and its derivatives and its preparation method and apply. Background technique [0002] Cardiovascular and cerebrovascular diseases are currently the most serious disease that endangers human life and health, and are common and frequently-occurring diseases among middle-aged and elderly people. It ranks first in morbidity and mortality in many countries. Atherosclerosis is the basis of many cardiovascular and cerebrovascular diseases. A large number of experimental and clinical data prove that atherosclerosis is closely related to abnormal blood lipid metabolism. Therefore, lipid-regulating drugs have become an important field of current drug research. [0003] Through prospective, random and controlled clin...
