ARYL PIPERIDINE DERIVATIVES AS INDUCERS OF LDL-RECEPTOR EXPRESSION

摘要

The invention relates to a compound of formula (I), wherein Ar1 represents phenyl, naphthyl or phenyl fused by a C3-8cycloalkyl, where each group is optionally substituted by methylenedioxy or one or two groups independently represented by R<1>; Ar2 represents phenyl or a 5-6 membered heteroaromatic group, where each group is optionally substituted by one to four groups independently selected from halogen, C1-4 alkyl and C1-4 alkoxy; Ar3 represents a phenyl or a 5-6 membered heteroaromatic group, where each group is optionally substituted by one to four groups independently selected from hydroxy, alkyl, C1-4 alkoxy, C2-4 alkenyl, C2-4 alkenyloxy, C1-4 perfluoroalkoxy, C1-4 acylamino or an electron withdrawing group; A represents -C(H)-; E represents -C1-6 alkylene-; X represents -CON(H or C1-4alkyl)- or -N(H or C1-4alkyl)CO-; Y represents a direct link; R<1> represents halogen, -S(C1-4 alkyl)-, -O-(C0-4 alkylene)-R<2> or -(C0-4alkylene)-R<2>, where each alkylene group may additionally incorporate an oxygen in the chain, with the proviso that there are at least two carbon atoms between any chain heteroatoms; R<2> represents: i) hydrogen, C1-4 perfluoroalkyl, C2-3 alkenyl, ii) phenyl, naphthyl, a 5- or 6-membered heteroaromatic group or 1,2,3,4-tetrahydronaphthyl, optionally substituted by one or two halogen, hydroxy, C1-4 alkyl, C1-4 alkoxy groups, iii) C3-8cycloalkyl, a 3-7 membered heterocycloalkyl, iv) amino, C1-4 alkylamino or di-C1-4alkylamino, with the proviso that there are at least two carbon atoms between any chain heteroatoms; to salts, solvates and compositions thereof and their use in treating disorders associated with elevated levels of circulating LDL-cholesterol.
