The present invention relates to a compound of formula (I) or a pharmaceutically acceptable salt thereof:
wherein R
1
represents C
1-6
alkyl or C
3-6
cycloalkyl, either of which is optionally substituted with 1, 2 or 3 halogen atoms; and
R
2
represents hydrogen, halogen, C
1-6
alkyl or C
3-6
cycloalkyl; and either of said C
1-6
alkyl or C

cycloalkyl is optionally substituted with 1, 2 or 3 halogen atoms.
The pyrazole compounds of formula (I) or salts thereof modulate P2X7 receptor function and are capable of antagonizing the effects of ATP at the P2X7 receptor (P2X7 receptor antagonists). The invention also relates to the use of such compounds or salts, or pharmaceutical compositions thereof, in the treatment or prevention of disorders/diseases mediated by the P2X7 receptor, for example pain, inflammation or a neurodegenerative disease.
本发明涉及公式(I)的化合物或其药学上可接受的盐:
其中,R1代表C1-6烷基或C3-6环烷基,其中任意一种均可选用1、2或3个卤素原子进行取代;而R2代表氢、卤素、C1-6烷基或C3-6环烷基;所述的C1-6烷基或C3-6环烷基中的任意一种均可选用1、2或3个卤素原子进行取代。
公式(I)的吡唑化合物或其盐可以调节P2X7受体功能,并能够拮抗ATP在P2X7受体上的作用(P2X7受体拮抗剂)。本发明还涉及在治疗或预防由P2X7受体介导的疾病/疾病(例如疼痛、炎症或神经退行性疾病)中使用这种化合物或盐,或其制剂。
