The present invention relates to a compound of formula (I) or a pharmaceutically acceptable salt thereof:
wherein: R
2
represents hydrogen, halogen, C
1-6
alkyl, C
6-10
arylmethyl-, C
2-6
alkenyl, C
2-6
alkynyl or C
3-6
cycloalkylmethyl-; and any of said C
1-6
alkyl, C
6-10
arylmethyl-, C
2-6
alkenyl, C
2-6
alkynyl or C
3-6
cycloalkylmethyl- is optionally substituted with 1, 2 or 3 halogen atoms; and R
3
represents hydrogen, fluorine or methyl;
or R
2
and R
3
together with the carbon atoms to which they are attached form a benzene ring optionally substituted with 1, 2 or 3 substituents, which may be the same or different, selected from the group consisting of C
1-6
alkyl, C
2-6
alkenyl and C
2-6
alkynyl.
The compounds or salts modulate P2X7 receptor function and are capable of antagonizing the effects of ATP at the P2X7 receptor. The invention also provides the use of such compounds or salts, or pharmaceutical compositions thereof, in the treatment of disorders mediated by the P2X7 receptor, for example pain, inflammation or neurodegeneration.
本发明涉及式(I)的化合物或其药学上可接受的盐:其中:R2代表氢、卤素、C1-6烷基、C6-10芳基甲基、C2-6烯基、C2-6炔基或C3-6环烷基甲基;所述的任何C1-6烷基、C6-10芳基甲基、C2-6烯基、C2-6炔基或C3-6环烷基甲基均可选地用1、2或3个卤素原子取代;R3代表氢、氟或甲基;或R2和R3与它们连接的碳原子一起形成一个苯环,该苯环可选地用1、2或3个取代基取代,所述取代基可以是相同的或不同的,选自C1-6烷基、C2-6烯基和C2-6炔基的群。这些化合物或盐调节P2X7受体功能,并能够拮抗ATP在P2X7受体的作用。本发明还提供了这种化合物或盐的用途,或其制成的药物组合物,用于治疗由P2X7受体介导的疾病,例如疼痛、炎症或神经退行性疾病。
