A family of structurally rigid dopamine D3 receptor selective ligands is described. The family of structurally rigid dopamine D3 receptor selective ligands has the formula wherein A is cis or trans —CH═CH—, —C═C—, or cyclohexyl. B is cis or trans —CH═CH— or absent. R1 represents an optionally substituted phenyl group, wherein said substituents are selected from the group consisting of: hydrogen, halogen, amino, nitro, hydroxyl, alkoxy, alkyl, acyl and pyridyl, and said substitution may occur at any of the ortho, meta, or para positions, or R1 represents a heteroaromatic ring. A preferred heteroaromatic ring is indole, quinoxoline, pyridyl, pyrimidyl, or imidazole. R2 and R3 may be independently hydrogen or a halogen, or R2 alone may be C1, C2, or C3 alkoxy, and m is 1 or 2, and n is 0, 1, or 2.
描述了一类结构刚性的多巴胺D3受体选择性配体。该结构刚性的多巴胺D3受体选择性配体的化学式如下:其中A为顺式或反式—CH═CH—、—C═C—或环己基;B为顺式或反式—CH═CH—或不存在;R1表示可选取代的苯基,所述取代基选自羟基、卤素、氨基、硝基、烷氧基、烷基、酰基和吡啶基,且该取代基可以出现在邻、间或对位上,或者R1表示杂环芳基。优选的杂环芳基为吲哚、喹啉、吡啶基、嘧啶基或咪唑基。R2和R3可独立地为氢或卤素,或者仅R2为C1、C2或C3的烷氧基,m为1或2,n为0、1或2。
