Aminopyrazole derivatives represented by formula (I), or salts thereof, wherein X1 and X2 are each a hydrogen atom or a halogen atom, or X1 and X2 may be united together to form a lower alkylenedioxy group, Q is a pyridyl group or a quinolyl group, R1 is a hydrogen atom, a substituted or unsubstituted lower alkyl or aryl group, R2 is a hydrogen atom, a lower alkyl group, or an aralkyl group, and R3 represents a hydrogen atom, an organic sulfonyl group, or -C(=Y)-R4 in which R4 is a hydrogen atom or an organic residue and Y is an oxygen or sulfur atom, provided that, when R3 is a hydrogen atom, R1 is a group other than a hydrogen atom and R2 is a hydrogen atom. These aminopyrazole derivatives or their salts have excellent p38MAP kinase inhibiting activities and are hence useful in the prevention or treatment of diseases associated with tumor necrosis factor α, interleukin 1, interleukin 6 or cyclooxygenase II.
由式(I)代表的氨基吡唑衍生物或其盐,其中X1和X2各自为氢原子或卤原子,或X1和X2可结合在一起形成低级亚烷基二氧基,Q为吡啶基或喹啉基,R1为氢原子、取代或未取代的低级烷基或芳基、R2 是氢原子、低级烷基或芳烷基,R3 代表氢原子、有机磺酰基或-C(=Y)-R4,其中 R4 是氢原子或有机残基,Y 是氧原子或硫原子,但当 R3 是氢原子时,R1 是氢原子以外的基团,R2 是氢原子。这些氨基吡唑衍生物或其盐类具有优异的 p38MAP 激酶抑制活性,因此可用于预防或治疗与肿瘤坏死因子 α、白细胞介素 1、白细胞介素 6 或环氧合酶 II 有关的疾病。
