Biphenylylquinuclidine derivatives of formula I, Q--Ar.sup.1 --Ar.sup.2, in which Q is of formula Ia or Ib, ##STR1## in which R.sup.1 and R.sup.2 are independently selected from hydrogen, alkyl, halogeno and hydroxy; or R.sup.1 and R.sup.2 when taken together define an oxo group; Xb is selected from --CH.sub.2 --, .dbd.CH-- and --CH(OH); Xa is selected from --CH.sub.2 --, .dbd.CH--, CO, --O--, and --S(O)n (wherein n=0, 1 or 2); Ar.sup.1 is a phenylene moiety; Ar.sup.2 is phenyl; and wherein one or both of Ar.sup.1 and Ar.sup.2 is optionally unsubstituted or substituted by one or more substituents independently selected from halogeno, hydroxy, amino, nitro, cyano, carboxy, carbamoyl, alkyl, alkenyl, alkynyl, alkoxy, alkylamino, di-alkylamino, N-carbamoyl, N,N-di-alkylcarbamoyl, alkoxycarbonyl, alkylthio, alkylsulphinyl, alkylsulphonyl, halogeno-alkyl, alkanoyl and alkanoylamino; and their pharamaceutically acceptable salts are inhibitors of squalene synthase and hence useful in treating diseases and medical conditions in which a lowering of cholesterol is desirable. The use of these derivatives in medicine is disclosed tohether with novel compounds, processes for their preparation and pharmaceutical composition containing them.
公式I的二苯基喹啉衍生物,Q--Ar.sup.1 --Ar.sup.2,其中Q为公式Ia或Ib,##STR1##其中R.sup.1和R.sup.2分别独立地选择自氢、烷基、卤代和羟基;或者当R.sup.1和R.sup.2一起定义一个氧代基时;Xb从--CH.sub.2 --、.dbd.CH--和--CH(OH)中选择;Xa从--CH.sub.2 --、.dbd.CH--、CO、--O--和--S(O)n(其中n=0、1或2)中选择;Ar.sup.1是苯基亚甲基;Ar.sup.2是苯基;其中Ar.sup.1和Ar.sup.2中的一个或两个是选择性地未取代或由一个或多个取代基独立地选择性取代,这些取代基来自卤代、羟基、氨基、硝基、氰基、羧基、氨基甲酰基、烷基、烯基、炔基、烷氧基、烷基氨基、二烷基氨基、N-氨基甲酰基、N,N-二烷基氨基甲酰基、烷氧羰基、烷基硫醚、烷基磺醇、烷基磺酰基、卤代烷基、烷酰基和烷酰氨基;它们的药学上可接受的盐是皂化酶的抑制剂,因此在治疗需要降低胆固醇的疾病和医疗状况中有用。在医学上披露了这些衍生物的用途,以及新颖化合物、其制备方法和含有它们的药物组合物。
