CA 2303839

The present invention relates to new piperidyl- or piperazinyl-substituted indan derivatives having formula (I) wherein X is N or CH; Y is NR2HC2, CH2NR2, NR2CO, CONR2 or NR2SO2, wherein R2 is H or C1-C6 alkyl; R1 is H, C1-C6 alkyl or C3-C6 cycloalkyl; R3 is C1-C6 alkyl, C3-C6 cycloalkyl or (CH2)n-aryl, wherein aryl is phenyl or a heteroaromatic ring containing one or two heteroatoms selected from N, O and S which may be mono- or di-substituted; n is 0-4; R9 is H, C1-C6 alkyl, C3-C6 cycloalkyl OCF3, OCHF2, OCH2F, halogen, CN, CF3, OH, C1-C6 alcoxy, C1-C6 alcoxy-C1-C6 alkyl, NR6R7, SO3CH3, SO3CF3, SO2NR6R7, an unsubstituted or substituted heterocyclic or heteroaromatic ring containing one or two heteroatoms selected from N and O, wherein the substituent(s) is(are) C1-C6 alkyl; or COR8, wherein R6, R7 and R8 are as defined above, as R-enantiomers, S-enantiomers or racemates in the form of a free base or pharmaceutically acceptable salts or solvates thereof, a process for their preparation, pharmaceutical compositions containing said therapeutically active compounds and to the use of said active compounds in therapy.

Ces dérivés se présentent sous forme de R-énantiomères, S-énantiomères ou racémates sous la forme d'une base libre ou de sels pharmaceutiquement acceptables ou des solvates de ceux-ci. L'invention concerne également leur procédé de préparation, les compositions pharmaceutiques contenant ces composés d'action thérapeutique et l'utilisation de ces composés actifs en thérapie.
