The invention provides a compound of the formula (I): for use in medicine: or salts or tautomers or N-oxides or solvates thereof; wherein R
1
is an optionally substituted heterocyclic group having from 3 to 12 ring members provided that the cyclic group joined to the pyrazole contains at least one heteroatom selected from N, O or S; A is a bond or —Y—(B)
n
—; B is C═O, NR
g
(C═O) or O(C═O) wherein R
g
is hydrogen or C
1-4
hydrocarbyl optionally substituted by hydroxy or C
1-4
alkoxy; n is 0 or 1; Y is a bond or an alkylene chain of 1,2 or 3 carbon atoms in length; R
2
is hydrogen; halogen; C
1-4
alkoxy (e.g. methoxy); or a C
1-4
hydrocarbyl group optionally substituted by halogen (e.g. fluorine), hydroxyl or C
1-4
alkoxy (e.g. methoxy); R
3
is selected from optionally substituted carbocyclic and heterocyclic groups having from 3 to 12 ring members or an optionally substituted C
1-8
hydrocarbyl group; with the proviso that R
1
is not formula (II): where X, R
3′
and R
4′
are defined in the claims.
该发明提供了一种具有以下化学式(I)的化合物,用于医药用途:或其盐或互变异构体或N-氧化物或溶剂化物;其中R1是一个可选择取代的杂环基团,具有3到12个环成员,但与吡唑环连接的环中至少包含N、O或S中的一个杂原子;A是一个键或—Y—(B)n—;B是C═O、NRg(C═O)或O(C═O),其中Rg是氢或C1-4烃基,可选择取代为羟基或C1-4烷氧基;n为0或1;Y是一个键或长度为1、2或3个碳原子的烷基链;R2是氢、卤素、C1-4烷氧基(例如甲氧基)或可选择取代为卤素(例如氟)、羟基或C1-4烷氧基(例如甲氧基)的C1-4烃基;R3从具有3到12个环成员的可选择取代的碳环和杂环基团中选择或可选择取代的C1-8烃基;但R1不是化学式(II):其中X、R3'和R4'在权利要求中有定义。
