Synthesis and conformational studies of 3,4-di-O-acylated furanoid sugar amino acid-containing analogs of the receptor binding inhibitor of vasoactive intestinal peptide
摘要:
Structural analysis of the di-O-caprylated Gaa-containing analog of the receptor binding inhibitors of vasoactive intestinal peptide by various NMR techniques and constrained molecular dynamics (XID) simulation studies established a well-defined beta-turn structure in DMSO-d(6) with an intramolecular hydrogen bond between TyrNH -> MetCO.

Synthesis of 3,4-di- O -acylated glucose-derived furanoid sugar amino acids (Gaa): conformational analysis of a Leu-enkephalin analog containing di- O -myristoylated Gaa
3,4-Di-O-acylated derivatives 1–3 of a glucose-derived furanoidsugaraminoacid (Gaa) were synthesized as novel peptide building blocks to study their effects on peptideconformation. Structural analysis of the di-O-myristoylated Gaa 3-containing Leu-enkephalin analog 4 by various NMR techniques and constrained molecular dynamics (MD) simulation studies established a well-defined β-turn structure
3,4-二- ö -acylated衍生物1 - 3葡萄糖衍生的糖呋喃氨基酸(GAA)的合成为新的肽构建块来研究它们对肽的构象的影响。通过各种NMR技术和受约束的分子动力学(MD)模拟研究,对含二O-肉豆蔻酰化的GAA 3的亮脑啡肽类似物4进行结构分析,建立了具有分子内氢键的DMSO- d 6中定义明确的β-转角结构。在PheNH→TyrCO之间。
