It is intended to find an efficient method of searching for drugs affecting the cholesteryl ester cycle and establish a system of efficiently searching for defoaming agents or regression agents artherosclerotic lesion and a system of searching for therapeutic agents remedies for atherosclerosis with a mechanism different from publicly known ones. A method of evaluating effects of a test substance on intracellular cholesteryl ester metabolic regulation which comprises selectively extracting free cholesterol with an aqueous alcohol from cells having been incubated in the presence of the test substance and cells having been incubated in the absence of the test substance, and then comparing the cholesteryl ester content in the cells having been incubated in the presence of the test substance with the cholesteryl ester content in the cells having been incubated in the absence of the test substance; in particular, a method of screening a compound having an activity of regulating the intracellular cholesteryl ester metabolism; and defoaming promoters, antiatherogenic agents or agents for regression of atherosclerotic lesion containing as the active ingredient compounds screened by the above method.
本文旨在寻找一种有效的方法,以搜索影响
胆固醇酯循环的药物,并建立一种有效搜索
消泡剂或退行性动脉粥样硬化病变的系统,以及一种搜索机制与公开已知机制不同的动脉粥样硬化疗法的系统。一种评估试验物质对
胆固醇酯代谢调节的影响的方法,包括从已在试验物质存在和不存在的情况下孵育的细胞中,用
水性
酒精选择性提取游离
胆固醇,然后将存在试验物质的细胞中的
胆固醇酯含量与不存在试验物质的细胞中的
胆固醇酯含量进行比较;特别是筛选具有调节细胞内
胆固醇酯代谢活性的化合物的方法;以及包含通过上述方法筛选出的化合物作为活性成分的消泡
促进剂、抗动脉粥样硬化剂或动脉粥样硬化病变退行剂的药物。
