Naphthalene derivatives of the formula:
wherein
R1 is hydrogen atom or a lower alkoxycarbonyl and
R2 is a lower alkoxycarbonyl, or R' and R2 are combined together to form a group of the formula:
each of R3 and R4 is a lower alkoxy, or one of R3 and R4 is hydrogen atom and the other is a lower alkoxy, and
Ring A is a substituted or unsubstituted benzene ring, and a pharmaceutically acceptable salt thereof are disclosed. Said naphthalene derivative (I) and its salt have excellent hypolipidemic activity and are useful for treatment or prophylaxis of hyperlipidemia and/or arteriosclerosis. Disclosed are also a process for the production of compounds of formula (I), the use of said compounds and the production of medicaments and pharmaceutical compositions containing compounds of formula (1) as active ingredient.
式中的萘衍生物:
式中
R1 是氢原子或低级烷氧羰基,以及
R2 是低级烷氧羰基,或 R' 和 R2 结合在一起形成式中的基团:
R3 和 R4 中的每一个都是低级烷氧基,或 R3 和 R4 中的一个是氢原子,另一个是低级烷氧基,以及
环 A 是取代或未取代的苯环。所述萘衍生物(I)及其盐具有优异的降脂活性,可用于治疗或预防高脂血症和/或动脉硬化。还公开了一种生产式(I)化合物的工艺、所述化合物的用途以及含有式(1)化合物作为活性成分的药物和药物组合物的生产。
