A medicine or reagent comprising a bipyrazole derivative of the following formula (I), ##STR1## wherein R.sub.1 and R.sub.2 are individually a hydrogen atom, aryl group, alkyl group having 1-5 carbon atoms, or alkoxycarbonylalkyl group having a total of 3-6 carbon atoms, R.sub.3 and R.sub.4 are individually a hydrogen atom, alkyl group having 1-5 carbon atoms, cycloalkyl group having 5-7 carbon atoms, hydroxyalkyl group having 1-3 carbon atoms, benzyl group, naphthyl group, or substituted or unsubstituted phenyl group, as an active component. The medicine is useful for effectively capturing active oxygen and free radicals which cause adult diseases such as cerebral ischemia, heart disease, digestive system disease, and carcinoma, as well as inflammation, and for diagnosing diseases associated with in vivo free radicals.
一种药物或试剂,包括以下式(I)的双吡唑衍生物,其中R.sub.1和R.sub.2分别是氢原子、芳基、具有1-5个碳原子的烷基、或具有总共3-6个碳原子的烷氧羰基烷基;R.sub.3和R.sub.4分别是氢原子、具有1-5个碳原子的烷基、具有5-7个碳原子的环烷基、具有1-3个碳原子的羟基烷基、苄基、萘基,或取代或未取代的苯基,作为活性成分。该药物对于有效捕捉引起成人疾病(如脑缺血、心脏病、消化系统疾病和癌症)以及炎症的活性氧和自由基非常有用,并用于诊断与体内自由基相关的疾病。
