    • The present invention relates to N-null(1-dimethylaminocycloalkyl)methylnullbenzamide derivatives having the general formula I 1 wherein n is 0, 1, 2 or 3; R1 and R2 are independently H, (C1-4)alkyl or (C1-4)alkyloxy; R3 is (C3-8)alkyl, (C4-7)cycloalkyl, (C4-7)cycloalkyl (C1-3)alkyl, (C6-12)aryl(C1-3)alkyl (wherein the aryl moiety is optionally substituted with 1-3 substituents selected from (C1-4)alkyl, (C1-4)alkyloxy, halogen, trifluoromethyl and methoxycarbonyl), or (C4-9)heteroaryl(C1-3)alkyl; or a pharmaceutically acceptable salt thereof. The invention also relates to pharmaceutical compositions comprising said derivatives, and to the use of these N-null(1-dimethylaminocycloalkyl)methylnullbenzamide derivatives in the treatment of disorders or conditions which are responsive to inhibition of the GlyT-2 transporter, such as muscle spasticity, epilepsy and, particularly, acute, chronic and neuropathic pain.
    • 本发明涉及具有通式I的N - [(1-二甲基氨基环烷基)甲基]苯甲酰胺衍生物,其中n为0,1,2或3; R1和R2独立地为H,(C1-4)烷基或(C1-4)烷氧基; R3为(C3-8)烷基,(C4-7)环烷基,(C4-7)环烷基(C1-3)烷基,(C6-12)芳基(C1-3)烷基(其中芳基部分任选被 1-3个选自(C 1-4)烷基,(C 1-4)烷氧基,卤素,三氟甲基和甲氧基羰基的取代基)或(C 4-9)杂芳基(C 1-3)烷基; 或其药学上可接受的盐。 本发明还涉及包含所述衍生物的药物组合物,以及这些N - [(1-二甲基氨基环烷基)甲基]苯甲酰胺衍生物用于治疗对抑制GlyT-2转运蛋白有反应的病症或病症的用途,例如 肌肉痉挛,癫痫,特别是急性,慢性和神经性疼痛。
