contrast to the previously prepared S-substituted glutathiones, all of the title compounds exhibited noncompetitive inhibition of yeast glyoxalase I. A kinetic evaluation under Yonetani-Thorell conditions established the existence of two binding sites on the glyoxalase I enzyme.
通过将S-苄基-L-半胱氨酰甘氨酸或S-(对-溴苄基)-L-半胱氨酰甘氨酸与戊二酸酐,琥珀酸酐或适当封闭和活化的氨基酸缩合来制备八个S-和N-取代的L-半胱氨酰甘氨酸。与先前制备的S-取代的谷胱甘肽相反,所有标题化合物均显示出对酵母乙二醛酶I的非竞争性抑制。在Yonetani-Thorell条件下的动力学评估确定了乙二醛酶I酶上存在两个结合位点。
