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 orunsubstituted 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 X, 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,其活性成分包括由式 (I) 代表的化合物:
其中 R 代表直链或支链烷基;直链或支链烯基;低级卤代烷基;取代或未取代的环烷基;取代或未取代的环烯基;取代或未取代的环烷基烷基;一个取代或未取代的芳基,或一个取代或未取代的杂环基;Y代表-CO-或-SO2-,Z代表氢原子或巯基保护基团,或其原药化合物、药学上可接受的盐或水合物或溶液。式 (I) 所代表的化合物可通过选择性抑制 CETP 活性来增加 HDL,同时降低 LDL,因此有望成为一种新型的动脉粥样硬化或高脂血症预防或治疗药物。
