A compound represented by general formula (I), possible stereoisomer and optical isomer thereof, and pharmaceutically acceptable salts thereof, wherein R1, R2, R3 and R4 represent each hydrogen, etc.; R6 and R7 represent each optionally substituted lower alkyl; A represents a group of general formula (II) (wherein R5 represents hydrogen, etc.); and n is an integer of from 2 to 6. These compounds can suppress the formation of active oxygen and an increase in intracellular calcium and thus are useful as a remedy for ischemic diseases.
通式(I)代表的化合物、其可能的立体异构体和光学异构体及其药学上可接受的盐,其中 R1、R2、R3 和 R4 分别代表氢等;R6 和 R7 分别代表任选取代的低级烷基;A 代表通式(II)的基团(其中 R5 代表氢等);n 为 2 至 6 的整数。这些化合物可抑制活性氧的形成和细胞内钙的增加,因此可用于治疗缺血性疾病。
