The present invention relates to novel compounds of formula (I) or a pharmaceutically acceptable salt thereof:
1. wherein G is selected from a group consisting of: phenyl, pyridyl, benzothiazolyl, indazolyl; p is an integer ranging from 0 to 5;
R
1
is independently selected from a group consisting of: halogen, hydroxy, cyano, C
1-4
alkyl, haloC
1-4
alkyl, C
1-4
alkoxy, halo
1-4
alkoxy, C
1-4
alkanoyl; or corresponds to a group R
5
;
R
2
is hydrogen or C
1-4
alkyl;
R
3
is C
1-4
alkyl;
R
4
is hydrogen, or a phenyl group, a heterocyclyl group, a 5- or 6-membered heteroaromatic group, or a 8- to 11-membered bicyclic group, any of which groups is optionally substituted by 1, 2, 3 or 4 substituents selected from the group consisting of: halogen, cyano, C
1-4
alkyl, haloC
1-4
alkyl, C
1-4
alkoxy, C
1-4
alkanoyl;
R
5
is a moiety selected from the group consisting of: isoxazolyl, —CH
2
—N-pyrrolyl, 1,1-dioxido-2-isothiazolidinyl, thienyl, thiazolyl, pyridyl, 2-pyrrolidinonyl, and such a group is optionally substituted by one or two substituents selected from: halogen, cyano, C
1-4
alkyl, halo
1-4
alkyl, C
1-4
alkoxy, C
1-4
alkanoyl;
and when R
1
is chlorine and p is 1, such R
1
is not present in the ortho position with respect to the linking bond to the rest of the molecule; and when R
1
corresponds to R
5
, p is 1; or a salt thereof which are useful as modulators of dopamine D
3
receptors, e.g. to treat drug dependency or as antipsychotic agents.
本发明涉及公式(I)的新化合物或其药学上可接受的盐:1.其中G选自以下组中的一组:苯基,吡啶基,苯并噻唑基,吲哚基;p为0至5的整数;R1独立地选自以下组中的一组:卤素,羟基,氰基,C1-4烷基,卤代C1-4烷基,C1-4烷氧基,卤代1-4烷氧基,C1-4酰基;或对应于R5基团;R2为氢或C1-4烷基;R3为C1-4烷基;R4为氢,苯基,杂环基,5-或6-成员杂芳基,或8-至11-成员双环基中的一种,其中任何一种基团均可选择性地被1、2、3或4个来自以下组的取代基所取代:卤素,氰基,C1-4烷基,卤代C1-4烷基,C1-4烷氧基,C1-4酰基;R5是从以下组中选择的一部分:异噁唑基,-CH2-N-吡咯基,1,1-二氧化-2-异硫氮基,噻唑基,噻唑基,吡啶基,2-吡咯烷基,这样的基团可以选择地被一个或两个取代基所取代:卤素,氰基,C1-4烷基,卤代1-4烷基,C1-4烷氧基,C1-4酰基;当R1为氯且p为1时,该R1不位于与分子的其余部分的连接键的邻位上;当R1对应于R5时,p为1;或其盐,它们可用作多巴胺D3受体的调节剂,例如用于治疗药物依赖或作为抗精神病药物。
