The invention provides a compound of formula (I) or a pharmaceutically acceptable salt thereof: (I) wherein: A represents an aryl, heteroaryl or heterocyclyl group; and any ring or ring system of said aryl or heteroaryl is optionally substituted with 1 to 3 substituents, which may be the same or different, selected from the group consisting of halogen, C1-6 alkyl, -CF3, - OCF3, cyano, C1-6 alkoxy, -NR10R11, -X-aryl, -X-heteroaryl and -X-heterocyclyl; R1, R2, R3, R4 and R5 independently represent hydrogen, fluorine, chlorine, -CF3, cyano or C1-6 alkyl, such that at least one of R1, R2, R3, R4 and R5 is other than hydrogen; R6, R7, R8, R9, R10 and R11 independently represent hydrogen or C1-6 alkyl; X represents a linker selected from a bond, -(CH2)n- and -O-(CH2)n-; and n represents an integer from 1 to 3. The compounds or salts modulate P2X7 receptor function and are capable of antagonizing the effects of ATP at the P2X7 receptor ("P2X7 receptor antagonists").
本发明提供了一种式(I)化合物或其药学上可接受的盐:(I)其中:A代表芳基、杂芳基或杂环基团;上述芳基或杂芳基的任何环或环系可选地被1至3个取代基取代,这些取代基可以相同或不同,选自卤素、C1-6烷基、-CF3、-OCF3、氰基、C1-6烷氧基、-NR10R11、-X-芳基、-X-杂芳基和-X-杂环基;R1、R2、R3、R4和R5各自独立地代表氢、氟、氯、-CF3、氰基或C1-6烷基,使得R1、R2、R3、R4和R5中至少有一个不是氢;R6、R7、R8、R9、R10和R11各自独立地代表氢或C1-6烷基;X代表连接子,选自键、-(CH2)n-和-O-(CH2)n-;n代表1至3的整数。这些化合物或盐能够调节P2X7受体功能,并能拮抗ATP在P2X7受体上的效应(“P2X7受体拮抗剂”)。
