14元环异酪氨酸是从茜草科植物中获得的RA系列抗肿瘤双环肽的核心结构。在这项研究中,一个有效的方法合成环异酪氨酸从商业上可获得的L-酪氨酸衍生物。利用合成的环异酪氨酸和结构修饰的环异酪氨酸,设计并合成了几种RA-VII类似物,以探索RA-系列肽的环异酪氨酸部分的构效关系,并合成了新分离的天然肽以确定其结构。
The 14-membered cycloisodityrosine is the core structure of RA-series antitumor bicyclic peptides obtained from Rubia plants (Rubiaceae). In this study, an efficient method for the synthesis of cycloisodityrosines from commercially available l-tyrosine derivatives was developed. Using synthetic cycloisodityrosines and cycloisodityrosines with modified structures, several RA-VII analogues were designed and synthesized to explore structure–activity relationships of the cycloisodityrosine moiety of the RA-series peptides, and newly isolated natural peptides were synthesized to establish their structures.
