  摘要：

  犬胃泌素释放多肽（cGRP，其特征为类似于蚕豆蛋白的 27 个残基的多肽）是通过连续缩合 7 个纯度已确定的多肽片段，然后在三氟乙酸中用三氟甲磺酸进行脱保护而合成的。在去保护层之前，先用苯基硫代三甲基硅烷在一定量的三氟甲磺酸三甲基硅酯催化下进行短暂处理，还原受保护 cGRP 中的 Met(O) 残基。经 HPLC 纯化的均相产物与合成的人 GRP 相似，能显著提高大鼠血浆中的免疫活性胃泌素水平。

  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。

  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。

  A tetracontapeptide corresponding to the entire amino acid sequence of a frog skin peptide, sauvagine, was synthesized by assembling eight peptide fragments of established purity followed by deprotection with 1 M trimethylsilyl trifluoromethanesulfonate-thioanisole in trifluoroacetic acid. The synthetic peptide stimulated secretion of immunoreactive corticotropin from rat pituitary cells and its potency was estimated to be equivalent to that of synthetic ovine corticotropin releasing factor. Synthetic sauvagine displayed long-lasting hypotensive action in rats.

  The dotetracontapeptide corresponding to the revised amino acid sequence of porcine GIP (glucose-dependent insulinotropic polypeptide; originally named gastric inhibitory polypeptide) was synthesized by assembling eight peptide fragments of established purity, followed by thioanisole-mediated deprotection with trifluoromethanesulfonic acid in trifluoroacetic acid. The cycloheptyl esters of aspartic acid and glutamic acid were employed to suppress base-catalyzed side reactions. When tested in dogs, the synthetic peptide produced a significant increase of immunoreactive insulin in blood under background infusion of glucose.
