This invention relates to pyridazine derivatives represented by the formula (1):
wherein R
1
represents a (substituted) aryl group, R
2
represents a phenyl group substituted at 4-position by a lower alkoxyl, group or a lower alkylthio group, R
3
represents a lower alkoxyl group, a halogenated lower alkyl group, a lower cycloalkyl group, a (substituted) aryl group, a (substituted) aryloxy group, a (substituted) nitrogen-containing heterocyclic ring residue, a (substituted) aminocarbonyl group or a lower alkylcarbonyl group, A represents a single bond, a lower alkylene group or a lower alkenylene group, X represents O or S, and the dashed line indicates that the carbon-carbon bond between the 4-position and the 5-position is a single bond or a double bond, or salts thereof; and also to medicines containing them as effective ingredients. These compounds have excellent inhibitory activity against interleukin-1β production, and are useful as preventives and therapeutics for immune system diseases, inflammatory diseases, ischemic diseases and the like.
本发明涉及由式(1)表示的吡嗪衍生物:
其中R1表示(取代的)芳基基团,R2表示在4位被低烷氧基团或低烷硫基团取代的苯基基团,R3表示低烷氧基团、卤代的低烷基团、低环烷基团、(取代的)芳基基团、(取代的)芳氧基基团、(取代的)含氮杂环环残基、(取代的)氨基甲酰基团或低烷基甲酰基团,A表示单键、低烷基烷基或低烯基烷基,X表示O或S,虚线表示4位和5位之间的碳-碳键为单键或双键,或其盐;以及含有它们作为有效成分的药物。这些化合物具有优异的抑制白细胞介素-1β产生的活性,可用作预防和治疗免疫系统疾病、炎症性疾病、缺血性疾病等。
