Cyclic depsipeptides represented by the formula (1)
(wherein:
R is a straight or branched alkyl group of 5-20 carbon atoms or a straight or branched alkoxymethyl group of 5-15 carbon atoms; A, B, D, E and F independently each other are alanine, valine, leucine, isoleucine, phenylalanine, etc.; W and Z independently each other are aspartic acid, asparagine, glutamic acid or glutamine; and m and n independently each other is 0 or 1) or pharmacologically acceptable salts thereof. The present compounds are prepared according to a method conventionally used in peptide synthesis. The present compounds are useful as an agent for promoting the production of apolipoprotein E, a therapeutic agent for neurologic damages, a therapeutic agent for dementia, an agent for inhibiting the production of apolipoprotein B, an agent for promoting the production of apolipoprotein A1 or a therapeutic agent for hyperlipemia.
由式(1)代表的环状去肽类化合物
其中
R是5-20个碳原子的直链或支链烷基或5-15个碳原子的直链或支链烷氧基甲基;A、B、D、E和F各自独立地为丙氨酸、缬氨酸、亮氨酸、异亮氨酸、苯丙氨酸等;W和Z各自独立地为天冬氨酸、天冬酰胺、谷氨酸或谷氨酰胺;m和n各自独立地为0或1)或其药理学上可接受的盐。本化合物是按照肽合成的常规方法制备的。本化合物可用作促进脂蛋白 E 生成的制剂、神经损伤的治疗剂、痴呆症的治疗剂、抑制脂蛋白 B 生成的制剂、促进脂蛋白 A1 生成的制剂或高血脂症的治疗剂。
