Abstract
The invention discloses 2-acylamino-3-alkoxyl substituted pyridine compounds and an application of the compounds in treatment and / or prevention of atherosclerosis-induced cardiovascular diseases. Experiments verify that the compounds or pharmaceutical compositions have the function of up-regulating or stabilizing ABCA1 and SR-BI / CLA-1 and can be used for inhibiting bubblization of macrophage or enhancing cholesterolefflux of macrophage. Experiments show that the compounds have the effects of reducing blood fat and cholesterol and have an application prospect of becoming a medicine for reducing blood fat, treating atherosclerosis, cardiovascular diseases and the like.
Description
technical field [0001] The present invention relates to a class of 2-amido-3-alkoxypyridine compounds, which are used in the treatment and / or prevention of atherosclerotic cardiovascular diseases and belong to the field of pharmacy; , SR-BI / CLA-1, the application of lipid-lowering and cholesterol-lowering drugs; the present invention also relates to the preparation method of the compound; the present invention also relates to the pharmaceutical composition of the compound. Background technique [0002] Cardiovascular disease is the main killer of human health in developed countries and most developing countries. In recent years, with the improvement of people's material living standards, the incidence of cardiovascular and cerebrovascular diseases has shown an obvious upward trend, and the death rate of cardiovascular and cerebrovascular diseases accounts for the The composition of population death has reached 1 / 3. Atherosclerosis is the pathological basis of many serious c...
