arboxyanhydride (glyco-K NCA) monomers is described. These monomers employ C-linked sugars and amide linkages to lysine for improved stability without sacrificing biochemical properties. Three glyco-K NCAs were synthesized, purified, and found to undergo living polymerization using transition metal initiation. These are the first living polymerizations of glycosylated NCAs and were used to prepare
描述了新的糖基化-L-赖氨酸-N-羧酸酐(糖-K NCA)单体的制备。这些单体使用 C 连接的糖和酰胺键连接到赖氨酸以提高稳定性而不牺牲生化特性。合成、纯化了三种糖基 K NCA,并发现它们使用过渡金属引发进行活性聚合。这些是糖基化 NCA 的首次活性聚合,用于制备定义明确的高分子量糖多肽以及阻断和统计糖多肽。这种方法解决了从 N-羧酸酐直接合成糖多肽中与单体合成、纯化和聚合相关的许多长期存在的问题,并提供了具有 100% 糖基化的多肽。
