with the para isomer, [I]0.5 values for rat liver glyoxalase I and II were 925 and 12 microM, respectively. This is in marked contrast to other glyoxalase II competitive inhibitors, which in general are even more effective against glyoxalase I. The S-(o-, m-, and p-nitrocarbobenzoxy)glutathiones have found utility as affinity ligands for the purification of rat liver glyoxalase II and may well have use
合成和研究了哺乳动物肝乙二醛酶II的三种有效竞争性抑制剂,即S-(o-,间-和对-硝基羰基苯甲氧基)-谷胱甘肽。作为大鼠肝乙二醛酶II抑制剂的邻,间和对位异构体的Ki值分别为15、9和6.5 microM。谷胱甘肽衍生物虽然表现出明显的乙二醛酶II竞争性抑制作用,但几乎没有活性作为乙二醛酶I的抑制剂。例如,对于对位异构体,大鼠肝脏乙二醛酶I和II的[I] 0.5值分别为925和12 microM。这与其他乙二醛酶II竞争性抑制剂形成鲜明对比,后者通常对乙二醛酶I甚至更有效。S-(o-,m-,
