The related tripeptides glycyl-L-prolyl-L-glutamic acid (GPE) and glycyl-L-2-methylprolyl-L-glutamic acid (G-2-MePE) were labelled with commercially available [1,2,3,4,5-13C5, 2-15N1]-L-glutamic acid in 3 steps in excellent overall yield with high isotope incorporation. A related cyclic dipeptide was labelled with [2,2-2H2, 2-15N1]glycine giving a mixture of compounds resulting from deuterium scrambling
相关的三肽甘氨酰-L-脯氨酰-L-谷氨酸 (GPE) 和甘氨酰-L-2-甲基脯氨酰-L-谷氨酸 (G-2-MePE) 用市售 [1,2,3,4, 5-13C5, 2-15N1]-L-谷氨酸分 3 个步骤以优异的总收率和高同位素掺入量获得。相关的环状二肽用 [2,2-2H2, 2-15N1] 甘氨酸标记,得到由氘扰乱产生的化合物混合物。版权所有 © 2006 John Wiley & Sons, Ltd.
