The present invention provides a compound of Formula (IA) or a pharmaceutically acceptable salt thereof:
wherein R
1
represents C
1-4
alkyl, C
2-6
alkenyl, C
2-6
alkynyl, C
3-6
cycloalkyl, C
3-6
cycloalkylmethyl-, phenyl-X— or heteroaryl, any of which may be optionally substituted; X represents —(CR
12
R
13
)
n
—; n represents 0 to 2; and R
7
, R
8
, R
9
, R
10
and R
11
independently represent H, halogen, or cyano; or optionally substituted C
1-6
alkyl, C
2-6
alkenyl, C
2-6
alkynyl or C
3-6
cycloalkyl; such that at least two of R
7
, R
8
, R
9
, R
10
and R
11
represent a group other than H and at least one of R
7
and R
11
represents a group other than H; and wherein the compound is other than N-[(2,4-dichlorophenyl)methyl]5-oxo-1-(phenylmethyl)-3-pyrrolidinecarboxamide. The compounds and salts are thought to modulate P2X7 receptor function and be capable of antagonizing the effects of ATP at the P2X7 receptor.
本发明提供了化合物式(IA)或其药学上可接受的盐:其中,R1代表C1-4烷基,C2-6烯基,C2-6炔基,C3-6环烷基,C3-6环烷基甲基,苯基-X-或杂环芳基,其中任何一个可以选择性地被取代;X代表-(CR12R13)n-;n代表0到2;R7、R8、R9、R10和R11分别独立地代表H、卤素或
氰基;或可选择性地取代的C1-6烷基,C2-6烯基,C2-6炔基或C3-6环烷基;其中至少有两个R7、R8、R9、R10和R11代表除H以外的基团,且至少有一个R7和R11代表除H以外的基团;所述化合物不同于N-[(2,4-二
氯苯基)甲基]5-氧代-1-(苯基甲基)-3-
吡咯烷基甲酰胺。这些化合物和盐被认为可以调节P2X7受体功能,并能够拮抗
ATP在P2X7受体上的作用。
