    • The present invention relates to a compound of formula (I) or a pharmaceutically acceptable salt thereof: (I) wherein R1 represents C1-6 alkyl or C3-6 cycloalkyl, either of which is optionally substituted with 1, 2 or 3 halogen atoms; and R2 represents hydrogen, halogen, C1-6 alkyl or C3-6 cycloalkyl; and either of said C1-6 alkyl or C3-6 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.
    • 本发明涉及式(I)化合物或其药学上可接受的盐:(I)其中R 1表示C 1-6烷基或C 3-6环烷基,其任一个任选被1,2或3个卤素原子取代; 并且R 2表示氢,卤素,C 1-6烷基或C 3-6环烷基; 并且所述C 1-6烷基或C 3-6环烷基中的任一个任选被1,2或3个卤素原子取代。 式(I)的吡唑化合物或其盐调节P2X7受体功能,并且能够拮抗ATP在P2X7受体(P2X7受体拮抗剂)下的作用。 本发明还涉及这些化合物或其盐或其药物组合物在治疗或预防P2X7受体介导的疾病/疾病中的用途,例如疼痛,炎症或神经变性疾病。
