Nitroxyl compounds represented by general formula (I) which are usable in acquiring information about active oxygen or in vivo free radicals as biological images such as magnetic resonance images or magnetoencephalograms, wherein A represents hydrogen or -L-(CH2)n-OCOR (wherein L represents -COO- or -alkylene-COO-; and R represents C1-4 alkyl); R1, R2, R3, and R4 represent each C1-4 alkyl; and n is a number of from 1 to 4. Drugs and reagents containing the above compounds are usable in preventing, treating or diagnosing ischemic diseases, digestive diseases, cancer, cranial nervous diseases accompanied by nerve degeneration, inflammation, cataracts, or drug-induced organopathy.
通式(I)代表的硝氧化合物,可用于获取活性氧或体内自由基的信息,作为生物图像,如磁共振图像或磁共振脑电图,其中 A 代表氢或-L-(CH2)n-OCOR(其中 L 代表-COO-或-亚烷基-COO-;R 代表 C1-4 烷基);R1、R2、R3 和 R4 分别代表 C1-4 烷基;n 是 1 到 4 的数字。含有上述化合物的药物和试剂可用于预防、治疗或诊断缺血性疾病、消化系统疾病、癌症、伴有神经变性的颅神经疾病、炎症、白内障或药物引起的器官病变。
