Abstract

##STR1## Aminopyrazole derivatives represented by formula (I), or salts thereof, wherein X.sup.1 and X.sup.2 are each a hydrogen atom or a halogen atom, or X.sup.1 and X.sup.2 may be united together to form a lower alkylenedioxy group, Q is a pyridyl group or a quinolyl group, R.sup.1 is a hydrogen atom, a substituted or unsubstituted lower alkyl or aryl group, R.sup.2 is a hydrogen atom, a lower alkyl group, or an aralkyl group, and R.sup.3 represents a hydrogen atom, an organic sulfonyl group, or --C(.dbd.Y)--R.sup.4 in which R.sup.4 is a hydrogen atom or an organic residue and Y is an oxygen or sulfur atom, provided that, when R.sup.3 is a hydrogen atom, R.sup.1 is a group other than a hydrogen atom and R.sup.2 is a hydrogen atom. These amimopyrazole 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 sis factor .alpha., interleukin 1, interleukin 6 or cyclooxygenase II.
