The invention provides a compound of formula (I) or a pharmaceutically acceptable salt thereof wherein: A is C1-6alkyl, C3-6cycloalkyl, -CH2-R6, -CHMe-R7, -CMe2-R7, or optionally substituted aryl; wherein, when A is optionally substituted aryl, said aryl group is optionally substituted with 1 to 3 substituents, which may be the same or different, selected from the group consisting of halogen, C1-6alkyl, -CF3, C1-4alkoxy, C1fluoroalkoxy, cyano, NR8R9; and pyridyl wherein the pyridyl is optionally substituted by one methyl; R1 is chlorine, fluorine, -CF3, cyano or C1-6alkyl; R2, R3 and R5 independently are hydrogen, fluorine, chlorine, -CF3, cyano or C1-6alkyl, such that at least one of R2, R3 and R5 is other than hydrogen; R4 is hydrogen. These compounds and salts are thought to be P2X7 receptor antagonists. The invention also provides the use of the compound or salt for the manufacture of a medicament for the treatment of pain, inflammation, rheumatoid arthritis, osteoarthritis, or a neurodegenerative disease.
该发明提供了一个具有以下式(I)的化合物或其药用盐,其中:A为C1-6烷基,C3-6环烷基,-CH2-R6,-CHMe-R7,-CMe2-R7或可选择地取代的芳基;其中,当A为可选择地取代的芳基时,所述芳基可选择地取代为1至3个取代基,这些取代基可以相同或不同,选自卤素,C1-6烷基,-CF3,C1-4烷氧基,C1氟烷氧基,氰基,NR8R9;和吡啶基,其中吡啶基可选择地被一个甲基取代;R1为氯,氟,-CF3,氰基或C1-6烷基;R2、R3和R5独立地为氢,氟,氯,-CF3,氰基或C1-6烷基,使得R2、R3和R5中至少有一个不是氢;R4为氢。这些化合物和盐被认为是P2X7受体拮抗剂。该发明还提供了该化合物或盐用于制备用于治疗疼痛、炎症、类风湿关节炎、骨关节炎或神经退行性疾病的药物的用途。
