be used for solid-phase peptide synthesis, were designed and synthesized. Furthermore, a helical octapeptide with the following amino acid sequence was prepared, and its preferred conformation was analyzed based on its CD spectra: Ac-X1EYSAX2KA-NH2 (11: X1 = ApiC4N3, X2 = Ac6c). The side-chain azido functional group of peptide 11 was efficiently converted to various 1,2,3-triazole groups via Huisgen
设计并合成了具有功能化侧链的预组织环状α,α-二取代α-氨基酸(dAA),该功能化侧链可作为肽螺旋诱导剂,可用于固相肽合成。此外,制备具有以下氨基酸序列的螺旋八肽,并基于其CD光谱分析其优选的构象:Ac-X 1 EYSAX 2 KA-NH 2(11:X 1 = Api C4N3,X 2 = Ac 6 C)。肽11的侧链叠氮基官能团通过涉及不同类型炔烃的Huisgen 1,3-偶极环加成反应可将其有效地转化为各种1,2,3-三唑基团。结合构象预组织和侧链官能团优势的新型环状dAA衍生物应被证明是进一步开发生物活性肽的有用工具。
