AbstractWe examine the effect of crown ether ring sizes on structure and properties of three terminally protected tripeptides containing substituted dehydrophenylalanine residues; \(\hbox Bz-}\Delta \hbox Phe}\)(12-crown-4)-Phe-Phe-OMe, \(\hbox Bz-}\Delta \hbox Phe}\)(15-crown-5)-Phe-Phe-OMe, \(\hbox Bz-}\Delta \hbox Phe}\)(18-crown-6)-Phe-Phe-OMe. The resultant self-assembly of the peptides
摘要我们研究了冠醚环大小对含有取代的脱氢苯丙氨酸残基的三个末端保护的三肽的结构和性能的影响;\(\ hbox Bz-} \ Delta \ hbox Phe} \)(12-crown-4)-Phe-Phe-OMe,\(\ hbox Bz-} \ Delta \ hbox Phe} \)(15 -crown-5)-Phe-Phe-OMe,\(\ hbox Bz-} \ Delta \ hbox Phe} \)(18-crown-6)-Phe-Phe-OMe。肽的最终自组装产生纳米囊泡,其进一步转变为项链型结构,通过其SEM,LRTEM和AFM图像对其进行表征。我们还报告了在不同金属离子存在下这些囊泡的破坏。 图形概要:冠醚缀合的三肽P-12C4和P-15C5在存在\(\ hbox Hg} ^ 2 +} \)离子的情况下显示开启荧光。肽P-12C4和P-15C5自组装为纳米囊泡
