Quinuclidine derivatives of formula, and their pharmaceutically acceptable salts, in which: R.sup.1 is hydrogen or hydroxy; R.sup.2 is hydrogen; pr R.sup.1 and R.sup.2 are joined together so that CR.sup.1 -CR.sup.2 is a double bond; X is selected from --CH.sub.2 CH.sub.2 --, --CH.dbd.CH--, --C.dbd.C--, --CH.sub.2 O--, --OCH.sub.2 --, --CH.sub.2 NH--, NHCH.sub.2 --, --CH.sub.2 CO--, --COCH.sub.2 --, --CH.sub.2 S(O).sub.n -- and --S(O).sub.n CH.sub.2 -- wherein n is 0, 1 or 2; and AR is phenyl which may be optionally unsubstituted or substituted by one or more substituents such as halogeno, hydroxy, amino, nitro, cyano, carboxy, carbamoyl, alkyl, alkenyl, alkynyl, alkoxy, alkylamino, dialkylamino, N-alkylcarbamoyl, N,N-di-alkylcarbamoyl, alkoxycarbonyl, alkythio, alkylsulphinyl, alkylsulphonyl, halogeno alkyl, alkanoylamino, alkylenedioxy, alkanoyl and oxime derivatives thereof and O-alkyl ethers of said oximes; provided that when X is selected from --OCH.sub.2 --, --NHCH.sub.2 --, and SCH.sub.2 --, R.sup.1 is not hydroxy; inhibit squalene synthase and are useful in treating diseases or medical conditions in which inhibition of squalene synthase is desirable. The use of such heterocyclic derivatives in treating conditions such as hypercholesterolemia, and atherosclerosis is referred to as well as novel compounds, processes for their preparation and pharmaceutical compositions containing them.
该配方中的喹诺啉衍生物及其药学上可接受的盐,其中:R.sup.1为氢或羟基;R.sup.2为氢;或者R.sup.1和R.sup.2相结合,使得CR.sup.1-CR.sup.2为双键;X从--CH.sub.2 CH.sub.2 --、--CH.dbd.CH--、--C.dbd.C--、--CH.sub.2 O--、--OCH.sub.2 --、--CH.sub.2 NH--、NHCH.sub.2 --、--CH.sub.2 CO--、--COCH.sub.2 --、--CH.sub.2 S(O).sub.n--和--S(O).sub.n CH.sub.2--中选择,其中n为0、1或2;AR为苯基,可以选择不取代或取代为一个或多个取代基,例如卤素、羟基、氨基、硝基、氰基、羧基、氨基甲酰、烷基、烯基、炔基、烷氧基、烷基氨基、二烷基氨基、N-烷基氨基甲酰、N,N-二烷基氨基甲酰、烷氧羰基、烷硫基、烷基磺酰基、卤素烷基、烷酰胺基、烷二氧基、烷酰基以及其氧吡啶衍生物和其O-烷基醚;但是当X从--OCH.sub.2 --、--NHCH.sub.2 --和SCH.sub.2 --中选择时,R.sup.1不是羟基;这些化合物抑制角鲨烯合酶并且在治疗需要抑制角鲨烯合酶的疾病或医疗情况中是有用的。这些杂环衍生物在治疗高胆固醇血症和动脉硬化等情况中的使用也被提到,以及新的化合物、其制备方法和含有它们的药物组成物。
