  The present invention provides a compound of formula (I) or a pharmaceutically acceptable salt thereof wherein A is hydrogen, C1-4alkyl, C3-6cycloalkyl, C1-3alkoxy, C1-3alkoxy C1-4alkyl, C1-2fluoroalkyl, halogen, NR6 R7, optionally substituted heteroaryl (Het), or optionally substituted phenyl, and R1, R2, R3, R4, R5, R6 and R7 are as defined in the description. The compounds or salts are thought to modulate P2X7 receptor function and to be capable of antagonizing the effects of ATP at the P2X7 receptor. The invention also provides the use of the compound or salt in the treatment or prophylaxis of, for example, inflammatory pain, neuropathic pain, visceral pain, rheumatoid arthritis, osteoarthritis or neurodegenerative disorders.

  本发明提供了一种式(I)化合物或其药学上可接受的盐，其中A为氢、C1-4烷基、C3-6环烷基、C1-3烷氧基、C1-3烷氧基C1-4烷基、C1-2氟烷基、卤素、NR6 R7、任选取代的杂芳基(Het)或任选取代的苯基，且R1、R2、R3、R4、R5、R6和R7如说明书中所定义。这些化合物或盐被认为能够调节P2X7受体功能，并能拮抗ATP在P2X7受体上的作用。本发明还提供了该化合物或盐在治疗或预防例如炎症性疼痛、神经性疼痛、内脏疼痛、类风湿性关节炎、骨关节炎或神经退行性疾病中的用途。
