Two building blocks, Boc-Lys(Bn4-DTPA)-OH and Fmoc-Lys(Bu4(t)-DTPA)-OH have been synthesized via the acylation of the epsilon-amino group of N(alpha)-protected lysine, using suitably protected tetra-esters of diethylene triamine pentaacetic acid (DTPA), a ligand with wide application as a chelating agent for complexing metal tons to peptides.
通过使用二乙烯三胺五乙酸(DTPA)的适当保护的四酯对N(α)-保护的赖氨酸的ε-氨基进行酰化反应,合成了两种结构单元,即Boc-Lys(Bn4-DTPA)-OH和Fmoc-Lys(Bu4(t)-DTPA)-OH。DTPA是一种广泛用作螯合剂以使金属离子与肽络合的配体。
