摘要： Compounds of formula (I) wherein R.sup.1 is hydrogen or hydroxy; R.sup.2 is hydrogen; or R.sup.1 and R.sup.2 are joined together so that CR.sup.1 14 CR.sup.2 is a double bond; X is selected from --Ch.sub.2 CH.sub.2 --, --C.dbd.CH--, --C.tbd.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); Ar is phenyl which bears one or more substituents independently selected from the groups (1-6C)alkyl, (2-6C)alkenyl, (2-6C)alkynyl, (1-6C)alkoxy, (1-6C)alkoxycarbonyl, (1-6C)alkoxycarbonyl(1-6C)alkyl, (1-6C)alkoxy(1-6C)alkyl, (1-6C)alkylamino, di-�(1-6C)alkyl!amino, carbamoyl, (1-6C) alkylcarbamoyl, di-�(1-6C)alkyl!carbamoyl, (1-6C)alkenyl and oxime derivatives thereof and O--(1-6C)alkyl ethers of said oximes (1-6C)alkylthio, (1-6C)alkylsulphinyl and (1-6C)alkylsulphonyl when substituted by one or more groups selected from (1-6C)alkoxycarbonyl, (1-6C)alkanoyl and oxime derivatives thereof and O-(1-6C)alkyl ethers of said oxime derivatives, (1-6C)alkanoylamimo, (1-6C)alkanoyloxy, (1-6C)alkanoyloxy(1-6)alkyl, carbamoyl, N-(1-6C)alkylcarbamoyl, N,N-di�(1-6C)alkyl!carbamoyl, amino, (1-6C)alkylamino, di-�(1-6C)alkyl!amino, (1-6C)alkoxy, (2-6C)alkenyloxy, (1-6C)alkylthio, (1-6C)alkylsulphinyl, (1-6C)alkylsulphonyl, halogeno(1-6C)alkyl (2-6C)alkenyl, (2-6C)alkynyl, phenyl, phenoxy, cyano, nitro, hydroxy and carboxy; and wherein Ar may bear further substituents; and their pharmaceutically acceptable salts inhibit squalene synthese and are hence useful in lowering cholesterol levels in blood plasma Processes for preparing compounds of formula (I) are also referred to as well as pharmaceutical compositions containing them and their use in medicine.
