The present invention provides a CETP activity inhibitor comprising as an active ingredient a compound represented by the formula (I):
wherein R represents a straight chain or branched alkyl group; a straight chain or branched alkenyl group; a lower haloalkyl group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted cycloalkenyl group; a substituted or unsubstituted cycloalkylalkyl group; a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, X1, X2, X3, and X4 may be the same or different and each represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower haloalkyl group; a lower alkoxy group; a cyano group; a nitro group; an acyl group; or an aryl group, Y represents —CO— or —SO2—, and Z represents a hydrogen atom or a mercapto-protecting group, or a prodrug compound, a pharmaceutically acceptable salt, or hydrate or solvate thereof. The compounds represented by the formula (I) can increase HDL and at the same time decrease LDL through selective inhibition of CETP activity and, therefore, is expected to be useful as a new type of a preventive or therapeutic agent for atherosclerosis or hyperlipidemia.
本发明提供了一种 CETP 活性抑制剂,其包含以下式(I)所表示的化合物作为活性成分:其中 R 代表直链或支链烷基基团;直链或支链烯基基团;较低卤代烷基基团;取代或未取代环烷基基团;取代或未取代环烯基基团;取代或未取代环烷基烷基基团;取代或未取代芳基团,或取代或未取代杂环基团,X1、X2、X3 和 X4 可相同也可不同,每个代表氢原子、卤原子、较低烷基基团、较低卤代烷基基团;较低烷氧基团;氰基;硝基;酰基;或芳基,Y 代表—CO—或—SO2—,Z 代表氢原子或巯基保护基团,或一种前药化合物、药学上可接受的盐,或其水合物或溶剂化合物。由式(I)表示的化合物可以通过选择性抑制 CETP 活性来增加高密度脂蛋白(HDL)并同时降低低密度脂蛋白(LDL),因此,预计可作为一种新型的预防或治疗动脉粥样硬化或高脂血症的药物。
