为了研究锚定在可溶性聚合物载体上的肽的含量和链长对肽无氨基末端反应性的影响,氯甲基化聚苯乙烯是在基质上合成肽的起始材料,由(氯甲基)苯乙烯与苯乙烯共聚而成。通过共聚,树脂上的氯甲基含量易于控制并且可再现。五肽-(Ala2-Leu3)- 和十肽-(Ala2-Leu3-Pro2-Leu3)- 的重复肽链延伸通过常规方法进行,使用具有不同 Ile 含量的可溶性聚合物载体–Ile,用作内部参考,通过对所得肽树脂的氨基酸分析来评估偶联产率。
This paper describes an original methodology for peptide bond synthesis avoiding toxic solvents and reactants. Ball-milling stoichiometric amounts of Boc-protected α-amino acid N-carboxyanhydrides (Boc-AA-NCA) or Boc-protected α-amino acid N-hydroxysuccinimideesters (Boc-AA-OSu) with α-amino acid alkyl ester salts in the presence of NaHCO3 and a minimal quantity of EtOAc led to the production of di-

Herein we correlate secondary structure perturbation with changes in the solid-state moleculararchitectures of an elongated hexagonal plate-shaped foldecture derived from the self-assembly of rigid 12-helical [small beta]-peptide foldamers to which...
