Starting from N- and C-protected aspartic or glutamic acids, new unnatural α-amino acids containing 3,4,5-trisubstituted 1,2,4-triazole heterocycles on their side chains have been synthesized. Two points of diversity could easily be achieved on the heterocyclic moiety, which could easily be incorporated in peptide sequences to modify or improve their pharmacokinetic properties.
从 N 和 C 保护的天冬氨酸或谷氨酸开始,已经合成了在其侧链上含有 3,4,5-三取代的 1,2,4-三唑杂环的新的非天然 α-氨基酸。杂环部分可以很容易地实现两点多样性,可以很容易地将其掺入肽序列中以修改或改善其药代动力学特性。
