The solid-phase synthesis of the linear peptide II (Ac-KKYTVSI-SAA2-KKITVSI) containing the novel sugar amino acid SAA2 [(2S,3S,6R)-6-aminomethyl-3-hydroxytetrahydropyran-2-carboxylic acid] is described. Structural analysis by NMR and CD in 50% aqueous methanol indicates that peptide II adopts a β-hairpin conformation, as reported earlier for the non-modified peptide I (Ac-KKYTVSINGKKITVSI).
包含新型糖氨基酸SAA 2 [(2 S,3 S,6 R)-6-氨基甲基-3-羟基四氢吡喃-2-的线性肽II(Ac-KKYTVSI-SAA 2 -KKITVSI)的固相合成描述[羧酸]。通过NMR和CD在50%甲醇水溶液中进行的结构分析表明,肽II具有β-发夹构象,正如之前针对非修饰肽I(Ac-KKYTVSI NG KKITVSI)报道的那样。
