摘要:
The present invention provides a compound of formula (I) or a pharmaceutically acceptable salt thereof: wherein A is hydrogen, C1-4alkyl, C3-6cycloalkyl, C1-3alkoxy, C1-3alkoxy C1-4alkyl, C1-2fluoroalkyl, halogen, NR6R7, optionally substituted heteroaryl (Het), or optionally substituted phenyl, and R1, R2, R3, R4, R5, R6 and R7 are as defined in the description. The compounds or salts are thought to modulate P2X7 receptor function and to be capable of antagonizing the effects of ATP at the P2X7 receptor. The invention also provides the use of the compound or salt in the treatment or prophylaxis of, for example, inflammatory pain, neuropathic pain, visceral pain, rheumatoid arthritis, osteoarthritis or neurodegenerative disorders.
摘要:
The present invention therefore provides compounds of formula (I) or pharmaceutically acceptable salts thereof: (I) processes for their preparation, pharmaceutical compositions containing the same and to their use in the treatment of gastrointestinal and other disorders.

摘要:
The present invention relates to novel pyrazole derivatives of formula (I) which bind to the P2X7 receptor and are capable of interfering with the effects of ATP at the P2X7 receptor: and the use of such compounds or pharmaceutical compositions thereof in the treatment of disorders mediated by the P2X7 receptor, for example pain, inflammation and neurodegeneration.
摘要:
The present invention relates to a compound of formula (I) or a pharmaceutically acceptable salt thereof: 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.
摘要:
A compound of the formula (I), or a pharmaceutically acceptable salt thereof, or a pharmaceutically acceptable solvate thereof, wherein, X represents a moiety of formula (a), in which A.sup.1 represents --CH.dbd.CH.dbd., NH, S or O; A.sup.2 represents an oxo or a thioxo group; A.sup.3 represents H or an alkylcarbonyl group; and A.sup.4 represents hydroxy or NR.sup.s R.sup.t wherein R.sup.s and R.sup.t each independently represents H or alkyl; R.sup.0 and R.sup.1 each independently represents hydrogen or an alkyl group; R.sup.2 represents OCH.sub.2 CO.sub.2 H, or an ester or amide thereof, or R.sup.2 represents a moiety of formula (b), wherein R.sup.4 and R.sup.5 each independently represent hydrogen, alkyl, hydroxyalkyl, cycloalkyl or R.sup.4 together with R.sup.5 represents (CH.sub.2).sub.n wherein n is 2, 3 or 4; and R.sup.3 represents hydrogen, halogen, alkyl or alkoxy or R.sup.3 together with R.sup.2 represents a moiety of formula (c) or an ester or amide thereof, wherein R represents hydrogen, alkyl, hydroxymethyl or a moiety of formula (CH.sub.2).sub.n CO.sub.2 H, wherein n is zero or an integer 1, 2 or 3, or an ester or amide thereof; a process for the preparation of such a compound, a pharmaceutical composition containing such a compound and the use of such a compound and composition in medicine.
