端基含甘露糖的聚赖氨酸的合成及其聚集行为
DOI: 10.3724/SP.J.1105.2013.13042, PP. 774-780
Keywords: 甘露糖,聚赖氨酸,糖肽,囊泡,胶束
Abstract:
设计合成了2种含炔基的甘露糖衍生物(A-Man和A-DiMan)及2-［2-(2-叠氮乙氧基)-乙氧基］-乙胺(N3-TEG-NH2).以N3-TEG-NH2为引发剂引发Nε-苄氧羰基-L-赖氨酸酸酐(Lys(Z)-NCA)的开环聚合,得到2种分子量不同的端基含叠氮基团的聚赖氨酸,N3-P(Lys(Z))15和N3-P(Lys(Z))35,分别与A-Man和A-DiMan进行点击化学反应得到4种端基含甘露糖的聚合物.用透射电镜研究了4种聚合物在水溶液中的聚集行为,结果表明,基于P(Lys(Z))15的2种糖聚合物聚集形成囊泡,而基于P(Lys(Z))35的2种糖聚合物则聚集形成胶束.
