A novel spiroquinone derivative having a high ABCA1 stabilization effect and being useful for prophylactic and/or therapeutic agents for various diseases developing hypo-high density lipoproteinemia is obtained. The novel spiroquinone derivative is a compound represented by the following formula:
wherein R1a, R1b, R1c and R1d each represents a hydrogen atom, a halogen atom, an alkyl group which may have a substituent, or an alkoxy group which may have a substituent, and R2a and R2b each represents a hydrogen atom, or an alkyl group which may have a substituent (e.g., a carboxyl group, an alkoxycarbonyl group, a carbamoyl group, and an N-substituted carbamoyl group), the groups R2a and R2b may bond together to form a hydrocarbon ring with an adjacent carbon atom, provided that compounds in which all of the groups R1a, R1b, R1c and R1d are t-butyl groups, and both of the groups R2a and R2b are hydrogen atoms or both of the groups R2a and R2b are methyl groups are excluded; or a pharmacologically acceptable salt thereof.
获得了一种新的螺环醌衍生物,具有高ABCAl稳定作用,并可用作预防和/或治疗各种发展低高密度脂蛋白血症的疾病的药物。新的螺环醌衍生物是由以下式表示的化合物:其中R1a、R1b、R1c和R1d分别表示氢原子、卤素原子、可能具有取代基的烷基或可能具有取代基的烷氧基,而R2a和R2b分别表示氢原子或可能具有取代基的烷基(例如,羧基、烷氧羰基、氨基甲酰基和N-取代氨基甲酰基),其中R2a和R2b的基团可以结合成与相邻碳原子形成的碳氢环,但排除所有基团R1a、R1b、R1c和R1d均为叔丁基基团,且R2a和R2b的基团均为氢原子或R2a和R2b的基团均为甲基基团的化合物;或其药学上可接受的盐。
