The invention relates to 2-naphthamide derivatives, in the form of bases or of salts, corresponding to the following general formula (I): ##STR1## in which: the Z-Y entity represents an N--CH.sub.2, C.dbd.CH or CH--CH.sub.2 group; R.sup.1 represents a hydrogen, fluorine, bromine or iodine atom or a hydroxyl, methoxy, nitrile or nitro group; R.sup.2 represents a hydrogen or bromine atom or a hydroxyl, methoxy, nitrile or nitro group; the R.sub.1 and R.sub.2 substituents both being situated on the same ring of the naphthamide unit or each being situated on one of the rings; R.sup.3 and R.sup.4 can be identical or different and each independently represent a hydrogen or chlorine atom or a methoxy or methyl group or an electron-withdrawing group. The invention also relates to their therapeutic applications as partial agonists of the dopamine D.sub.3 receptor. The invention applies more particularly to the treatment of neuropsychiatric conditions involving the dopamine D.sub.3 receptor, in particular psychotic and depressive states, to the treatment of drug-dependence states or to the treatment of disorders of a sexual nature.
本发明涉及2-萘酰胺衍生物,其形式为盐或碱,对应以下一般式(I):##STR1## 其中:Z-Y实体代表N-CH.sub.2,C.dbd.CH或CH-CH.sub.2基团;R.sup.1代表氢,氟,溴或碘原子或羟基,甲氧基,腈或硝基基团;R.sup.2代表氢或溴原子或羟基,甲氧基,腈或硝基基团;R.sub.1和R.sub.2取代基均位于萘酰胺单元的同一环上或各位于一个环上;R.sup.3和R.sup.4可以相同也可以不同,分别独立地代表氢或氯原子或甲氧基或甲基基团或电子吸引基团。本发明还涉及它们作为多巴胺D.sub.3受体的部分激动剂的治疗应用。本发明特别适用于治疗涉及多巴胺D.sub.3受体的神经精神疾病,特别是精神病和抑郁症,治疗药物依赖状态或治疗性质障碍。
