  • Patent number: 7605162
    Abstract: The invention relates to a novel group of phenylpiperazines having interesting pharmacological properties such as a high affinity for the dopamine D2 receptor and/or the serotonin reuptake site, and the ability to treat conditions related to disturbances in the dopaminergic and/or the serotonergic systems such as anxiety disorders, depression, Parkinson's disease, and schizophrenia. The invention relates to a group of novel phenylpiperazine derivatives of the formula (I): wherein: X is a group of formula 1, 2, 3, 4, 5, 6, or 7 as defined in the text, m has the value 2 to 6; n has the value 0-2; R5 and R6 are independently H or alkyl (1-3C); or R5+R6 represent a group —(CH2)—p wherein p has the value 3-5, and R7 is alkyl (1-3C), alkoxy (1-3C), halogen or cyano; or R6+R7 (R7 at position 7 of the indole group) represent a group —(CH2)q wherein q has the value 2-4, and salts thereof.

  • Patent number: 6780864
    Abstract: The invention relates to a group of novel piperazine and piperidine derivatives of formula (I), wherein: S1 is hydrogen, halogen, alkyl (1-3C), CN, CF3, OCF3, SCF3, alkoxy (1-3C), amino or mono- or dialkyl (1-3C) substituted amino, or hydroxy; X represents NR3, S, CH2, O, SO or SO2, wherein R3 is H or alkyl (1-3C); . . . Z represents ═C or —N; —R1 independently represent H or alkyl (1-3C), or R1 and R2 together can form a bridge 2 or 3 C-atoms; R4 is hydrogen or alkyl (1-3C); Q is methyl, ethyl, ethyl substituted with one or more fluorine atoms, cyclopropyl—methyl, optionally substituted with one or more fluorine atoms, and salts and prodrugs thereof. It has been found that these compounds have both partial dopamine D2-receptor agonism and partial serotonin 5-HT1A-receptor agonism mediated activities.
