The invention relates to A 1-(biphenyl-4-ylmethyl)imidazolidine-2,4-dione derivative having the general Formula I
wherein R1 is H, (C1-6)alkyl (optionally substituted with oxo, OR4, COOR5, halogen or CN), (C2-6)alkenyl, (C2-6)alkynyl, (C3-6)cycloalkyl or (C3-6)cycloalkyl(C1-3)alkyl; R2 and R2′ are independently H or (C1-3)alkyl; or R2 and R2′ form together with the carbon atom to which they are bound a (C3-5)cycloalkyl group; R3 represents H or 1 to 4 F substituents; Y represents
or NR8R9; X represents CHR6, CF2, O, S, SO or SO2; R4 and R5 are (C1-6)alkyl; R6 is H, OR7 or CN; R7 is (C1-3)alkyl; R8 is (C5-7)cycloalkyl comprising a heteroatom selected from O, S, SO and SO2; R9 is H or (C1-4)alkyl; o and m represent the ortho or meta position of the substituent Y—CH2; or a pharmaceutically acceptable salt thereof; as well as to the use of said 1-(biphenyl-4-ylmethyl)imidazolidine-2,4-dione derivatives in the treatment of pain such as for example peri-operative pain, chronic pain, neuropathic pain, cancer pain and pain and spasticity associated with multiple sclerosis.
本发明涉及一种具有通式I的1-(联苯基-4-甲基)咪唑啉-2,4-二酮衍生物,其中R1为H、(C1-6)烷基(可选地被氧代、OR4、COOR5、卤素或CN取代)、(C2-6)烯基、(C2-6)炔基、(C3-6)环烷基或(C3-6)环烷基(C1-3)烷基;R2和R2'分别为H或(C1-3)烷基;或R2和R2'与它们所连接的碳原子一起形成一个(C3-5)环烷基;R3代表H或1至4个F取代基;Y代表或NR8R9;X代表CHR6、CF2、O、S、SO或SO2;R4和R5为(C1-6)烷基;R6为H、OR7或CN;R7为(C1-3)烷基;R8为包含从O、S、SO和SO2中选择的杂原子的(C5-7)环烷基;R9为H或(C1-4)烷基;o和m表示取代基Y—CH2的邻位或间位;或其药学上可接受的盐;以及所述1-(联苯基-4-甲基)咪唑啉-2,4-二酮衍生物在治疗疼痛方面的用途,例如围手术期疼痛、慢性疼痛、神经病理性疼痛、癌症疼痛以及与多发性硬化相关的疼痛和痉挛。
