The invention relates to a group of new piperazine and piperidine compounds having interesting pharmacological properties. It has been found that compounds of the formula (a) <CHEM> wherein A represents a heterocyclic group of 5-7 ring atoms wherein 1 - 3 heteroatoms from the group O, N and S are present, R1 is hydrogen or fluoro, R2 is C1-4-alkyl, C1-4-alkoxy or an oxo group, and p is 0, 1 or 2, Z represents carbon or nitrogen, and the dotted line is a single bond when Z is nitrogen, and a single or double bond when Zis carbon, R3 and R4 independently are hydrogen or C1-4-alkyl, n has the value 1 or 2, R5 is 2-pyridyl, 3-pyridyl or 4-pyridyl substituted at the meta-position with respect to the methylene bridge with a group Y, and optionally substituted with (R6)q, Y is phenyl, furanyl or thienyl, which groups may be substituted with 1-3 substituents of the group hydroxy, halogen, CF3, C1-4-alkoxy, C1-4-alkyl, cyano, aminocarbonyl, mono- or di-C1-4-alkylaminocarbonyl, R6 is halogen, hydroxy, C1-4-alkoxy or C1-4-alkyl, and q is 0, 1, 2 or 3 and salts thereof, show affinities for both the dopamine D2-, D3-, D4- receptors and the serotonin 5-HT1A receptor. |
