  合成对应于鸵鸟促肾上腺皮质激素的整个氨基酸序列的壬二肽。

  摘要：

  对应的鸵鸟促肾上腺皮质激素（ACTH）的全氨基酸序列的非天然肽通过四个肽片段的连续缩合合成：Z(OMe)-(15-19)-OH, Z(OMe)-(11-14)-OH, Boc-(5-10)-OH 和 Z-(1-4)-NHNH2，与 H-(20-39)-OBzl（一种鸵鸟型促皮质素样中间叶肽的合成中间体）结合，然后使用1M三氟甲磺酸-噻吩甲烷在三氟乙酸中进行去保护。合成的肽具有相对于合成的人ACTH 0.8的体内甾体生成效力。

  The docosapeptide corresponding to the entire amino acid sequence of canine motilin, a newly characterized gastric motor activity-stimulating polypeptide, was synthesized by the conventional solution method. All protecting groups employed were removed by 1 M trifluoromethanesulfonic acid-thioanisole-trifluoroacetic acid and the deprotected peptide was purified by gel-filtration on Sephadex G-25, followed by partition chromatography and reverse phase high performance liquid chromatography. When contractile activity on rabbit duodenal muscle was examined, synthetic canine motilin was as active as synthetic porcine motilin. The relative potencies of Lys1 and Ser1 derivatives prepared in the same manner as canine motilin were ca. 1/1000 and 1/250, respectively.

  合成了与犬动脉肽（犬motilin）完整氨基酸序列对应的多肽，这是一种新特征的刺激胃肠运动活性的多肽，使用传统的溶液法合成。所有使用的保护基团均通过1 M三氟甲烷磺酸-硫醚-三氟乙酸去除，去保护的多肽通过Sephadex G-25的凝胶过滤进行纯化，随后进行分配色谱和反相高效液相色谱。在对兔十二指肠肌肉的收缩活性进行检验时，合成的犬动脉肽活性与合成的猪动脉肽相当。以与犬动脉肽相同的方法制备的赖氨酸1和丝氨酸1衍生物的相对效能分别约为1/1000和1/250。

  As a starting material for the synthesis of mouse epidermal growth factor, a half of the molecule, the protected tetracosapeptide ester (positions 30-53), was synthesized by successive condensations of eight peptide fragments : (positions 51-53), (49-50), (46-48), (42-45), (39-41), (37-38), (34-36), (30-33).

  Eight Met- and Leu-enkephalin analogs substituted with L- or D-Arg at position 2 were synthesized using NG-mesitylene-2-sulfonylarginine. Among them, H-Tyr-D-Arg-Gly-Phe-Met-OH was found to possess an analgesic effect 2.4 times higher than that of morphine on a molar basis, when injected intracisternally. This compound was also found to produce analgesia when administered intravenously.

  Two alternative deprotecting procedures were employed for the synthesis of porcine vasoactive intestinal polypeptide (VIP). Besides HF, TFA-thioanisole was found to cleave all the protecting groups employed, Z, Bzl and Mts, suppressing a newly found side reaction, i.e., acid-catalyzed succinimide formation from Asp residues with the free carboxyl group. A small amount of the N-terminal His residue linked to Ser-Asp was found to be released on standing at pH 6.

  猪血管活性肠肽(VIP)的合成采用了两种不同的脱保护程序。除了氢氟酸外，发现TFA-硫代茴香醚能裂解所用的所有保护基团，包括苄酯、甲砷酸和三甲基硅基，并抑制了一种新发现的副反应，即自由羧基的天冬氨酸残基在酸性催化下形成琥珀酰亚胺。在pH 6下静置时，与Ser-Asp相连的N端组氨酸残基有少量被释放。
