Naphthalene derivative of the formula: ##STR1## wherein R.sup.1 is hydrogen atom or a lower alkoxycarbonyl and R.sup.2 is a lower alkoxycarbonyl, or R.sup.1 and R.sup.2 are combined together to form a group of the formula: ##STR2## each of R.sup.3 and R.sup.4 is a lower alkoxy, or one of R.sup.3 and R.sup.4 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.
本发明揭示了一种萘衍生物的化学式:##STR1## 其中R.sup.1是氢原子或较低的烷氧羰基,R.sup.2是较低的烷氧羰基,或R.sup.1和R.sup.2结合在一起形成一个化学式的基团:##STR2## 其中R.sup.3和R.sup.4中的每一个都是较低的烷氧基,或者R.sup.3和R.sup.4中的一个是氢原子,另一个是较低的烷氧基,环A是取代或未取代的苯环,以及其药学上可接受的盐。所述的萘衍生物(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。
