  A new porcine gastrointestinal 29-residue peptide, galanin, was synthesized in a satisfactory yield by assembling seven peptide fragments followed by deprotection with 1 M trifluoromethane-sulfonic acid-thioanisole in trifluoroacetic acid. Nin-Mesitylenesulfonyltryptophan was employed to suppress indole alkylation during Na-deprotection. β-Cycloheptylaspartate was employed to suppress base-catalyzed succinimide formation. The synthetic peptide exhibited a powerful contractile activity on rat ileum, but not on guinea pig ileum and caused sustained hyperglycemia in dogs.

  一种新的猪胃肠道29残基肽——加拉宁，通过组合七个肽片段合成，并在三氟醋酸中使用1 M三氟甲烷磺酸-硫代苯醚进行去保护，获得了令人满意的产率。在钠去保护过程中，采用了九甲苯磺酰色氨酸以抑制吲哚烷基化。使用β-环庚基天冬氨酸来抑制碱催化的琥珀酰亚胺形成。合成的肽在大鼠回肠上表现出强有力的收缩活性，但在豚鼠回肠上没有影响，并且在狗身上引起持续性高血糖。

  Eight peptide fragments were prepared by known amide-forming reactions as building blocks for the solution synthesis of the dotetracontapeptide corresponding to the entire amino acid sequence of human intestinal GIP (gastric inhibitory polypeptide or glucose-dependent insulinotropic polypeptide). Besides Lys(Z), Trp(Mts) and Gln-OBzl, two new amino acid derivatives, Asp(OChp) and Glu(OChp) [Mts=mesitylenesulfonyl, Chp=cycloheptyl], were employed to suppress various side reactions. These fragments were successively assembled by the azide procedure to minimize racemization and all protecting groups employed were removed from the protected GIP by using 1M trifluoromethanesulfonic acid-thioanisole in trifluoroacetic acid.Synthetic GIP exhibited a significant glucose-dependent insulinotropic activity in dogs, but failed to produce any notable anti-gastric activity in rats.

  八个肽段通过已知的酰胺形成反应作为构建块，用于合成对应于人类肠道GIP（胃抑制多肽或葡萄糖依赖性胰岛素促进肽）完整氨基酸序列的四十肽。此外，除了Lys(Z)、Trp(Mts)和Gln-OBzl，还使用了两个新的氨基酸衍生物Asp(OChp)和Glu(OChp) [Mts=美克烯磺酰基，Chp=环庚基]，以抑制各种副反应。这些肽段通过叠氮化程序逐步组合，以最小化消旋化，所有使用的保护基团均通过在三氟乙酸中使用1M三氟甲烷磺酸-硫代苯醚去除。合成的GIP在犬中表现出显著的葡萄糖依赖性胰岛素促进活性，但未能在大鼠中产生任何显著的抗胃活性。

  Two enkephalin-containing peptides, peptide E and dynorphin (1-24), were synthesized by conventional solution methods employing a new Trp derivative, Nin-(2, 4, 6-triisopropylphenylsulfonyl)tryptophan [Trp(Tps)]. All protecting groups employed including the Tps group were removed by treatment with 1 M trifluoromethanesulfonic acid (TFMSA)-thioanisole in trifluoroacetic acid (TFA) at the final steps of these syntheses. Subsequent purifications by Sephadex G-25 chromatography, CM-Biogel A ion exchange chromatography, and reversed-phase high-performance liquid chromatography afforded highly purified samples. Both synthetic peptide E and dynorphin (1-24) exhibited high in vitro opioid activity. The usefulness of this new tryptophan derivative for practical peptide synthesis was established through these syntheses of complex Trp-containing peptides.

  我们采用一种新的 Trp 衍生物 Nin-(2,4,6-三异丙基苯磺酰基)色氨酸[Trp(Tps)]，通过传统的溶液方法合成了两种含脑啡肽的肽类--肽 E 和达因吗啡肽 (1-24)。在这些合成的最后步骤中，通过在三氟乙酸（TFA）中使用 1 M 三氟甲磺酸（TFMSA）-硫代苯甲醚处理，除去了包括 Tps 基团在内的所有保护基团。随后通过 Sephadex G-25 色谱、CM-Biogel A 离子交换色谱和反相高效液相色谱进行纯化，得到了高度纯化的样品。合成肽 E 和达因吗啡肽 (1-24) 在体外均表现出很高的阿片活性。通过这些含 Trp 的复杂多肽的合成，我们确定了这种新型色氨酸衍生物在实际多肽合成中的用途。

  A 36-residue peptide amide corresponding to the entire amino acid sequence of chicken antral peptide was synthesized by assembling seven peptide fragments via the azide, followed by thioanisole-mediated deprotection with trimethylsilyl bromide and trimethylsilyl trifluoromethanesulfonate in trifluoroacetic acid.The synthetic peptide stimulated gastric secretion, but not pancreatic secretion.
