The present invention relates to 1-[(indol-3-yl)carbonyl]piperazine derivative according to the general formula (I), wherein R represents 1-4 substituents independently selected from H, (C1-4)alkyl (optionally substituted with halogen), (C 1-4)alkyloxy (optionally substituted with halogen), halogen, OH, NH2, CN and NO2; R1 is (C5-8)cycloalkyl or (C5-8)cycloalkenyl; R2 is H, methyl or ethyl; R3, R3', R4' R4', R5, R5' and R6' are independently hydrogen or (C1-4)alkyl, optionally substituted with (C1-4)alkyloxy, halogen or OH; R6 is hydrogen or (C1-4)alkyl, optionally substituted with (C1-4)alkyloxy, halogen or OH; or R6 forms together with R7 a 4-7 membered saturated heterocyclic ring, optionally containing a further heteroatom selected from O and S; R7 forms together with R6 a 4-7 membered saturated heterocyclic ring, optionally containing a further heteroatom selected from O and S; or R7 is H, (C1-4)alkyl or (C3-5)cycloalkyl, the alkyl groups being optionally substituted with OH, halogen or (C1-4)alkyloxy; or a pharmaceutically acceptable salt thereof. The invention also relates to pharmaceutical compositions comprising said 1-[(indol-3-yl)carbonyl]piperazine derivatives, and to the use of these derivatives in the treatment of pain, such as peri-operative pain, chronic pain neuropathic pain, cancer pain, and pain and spasticity associated with multiple sclerosis.
本发明涉及根据通式(I)的1-[(indol-3-yl)carbonyl]哌嗪衍生物,其中R代表独立选择的1-4个取代基,包括H,(C1-4)烷基(可选择用卤素取代),(C1-4)烷氧基(可选择用卤素取代),卤素,羟基,氨基,氰基和硝基;R1为(C5-8)环烷基或(C5-8)环烯基;R2为H,甲基或乙基;R3,R3',R4',R4',R5,R5'和R6'独立地为氢或(C1-4)烷基,可选择用(C1-4)烷氧基,卤素或羟基取代;R6为氢或(C1-4)烷基,可选择用(C1-4)烷氧基,卤素或羟基取代;或R6与R7一起形成一个含有O和S等进一步杂原子的4-7元饱和杂环;R7与R6一起形成一个含有O和S等进一步杂原子的4-7元饱和杂环;或R7为H,(C1-4)烷基或(C3-5)环烷基,烷基基团可选择用羟基,卤素或(C1-4)烷氧基取代;或其药学上可接受的盐。该发明还涉及包含所述1-[(indol-3-yl)carbonyl]哌嗪衍生物的药物组合物,并且涉及在治疗疼痛方面使用这些衍生物,如围手术疼痛,慢性疼痛,神经病性疼痛,癌症疼痛以及与多发性硬化症相关的疼痛和痉挛。
