  Seven peptide fragments were synthesized by known amide-forming reactions as building blocks for the solution-phase synthesis of the heptatriacontapeptide amide corresponding to the entire amino acid sequence of human calcitonin gene-related peptide (hCGRP). S-1-Adamantyl-cysteine [O. Nishimura, C. Kitada, and M. Fujino, Chem. Pharm. Bull., 26, 1576 (1978)] was employed, together with amino acid derivatives bearing protecting groups removable by 1 M trifluoromethanesulfonic acid-thioanisole in trifluoroacetic acid.

  七个肽片段通过已知的酰胺形成反应合成，作为溶液相合成与人类降钙素基因相关肽（hCGRP）完整氨基酸序列相对应的七十氨基肽酰胺的构建块。采用了S-1-亚当烷基半胱氨酸 [O. Nishimura, C. Kitada, 和 M. Fujino, Chem. Pharm. Bull., 26, 1576 (1978)]，同时使用了具有保护基团的氨基酸衍生物，这些保护基团可通过1 M三氟甲磺酸-硫醇醚在三氟乙酸中去除。

  The tetratriacontapeptide amide corresponding to positions 1 to 34 of human parathyroid hormone, H-(hPTH 1-34)-NH2, was synthesized by the solution method. As a deprotecting reagent, 1M trifluoromethanesulfonic acid-thioanisole in trifluoroacetic acid was employed. When mouse bone adenyl cyclase activity was measured, our synthetic active fragment of human PTH exhibited an activity of 3380-4400 IU/mg.

  A recently found gastrointestinal hormone, PHI (heptacosapeptide), was synthesized in a different manner from that of Moroder et al. [Z. Naturforsch., 37b, 772 (1982) ]. Our synthesis was carried out by successive azide condensation of six peptide fragments (23-27, 19-22, 15-18, 11-14, 7-10, and 1-6), followed by deprotection with 1 M trifluoromethanesulfonic acid-thioanisole in trifluoroacetic acid. The deprotected peptide was purified by gel-filtration on Sephadex G-25, followed by ion-exchange chromatography on CM-Biogel A and reverse phase high-performance liquid chromatography on μBondapak C18. The homogeneous product thus obtained produced a remarkable decrease in systemic blood pressure in anesthetized rats. In addition, Nα-biotinyl-PHI was synthesized for histochemical receptor-binding studies.

  最近发现的一种胃肠激素PHI（七十七肽）与Moroder等人合成的方式不同[Z. Naturforsch., 37b, 772 (1982)]。我们的合成是通过六个肽片段（23-27、19-22、15-18、11-14、7-10和1-6）的连续叠加聚合反应进行的，随后用1 M三氟甲烷磺酸-硫醚在三氟乙酸中去保护。去保护的肽通过Sephadex G-25进行凝胶过滤纯化，随后进行CM-Biogel A上的离子交换色谱以及μBondapak C18上的反相高效液相色谱。由此获得的均匀产品在麻醉大鼠中显著降低了全身血压。此外，合成了Nα-生物素化-PHI用于组织化学受体结合研究。

  As a starting material for the synthesis of human parathyroid hormone (1-38), a C-terminal-protected eicosapeptide ester (positions 19-38) was synthesized by successive condensation of four peptide fragments; (positions 29-38), (25-28), (22-24) and (19-21).

  作为合成人甲状旁腺激素（1-38）的起始原料，通过连续缩合（29-38 位）、（25-28 位）、（22-24 位）和（19-21 位）四个肽段，合成了一个 C 端保护的二十肽酯（19-38 位）。

  The usefulness of a new deprotecting procedure was demonstrated in the solution syntheses of two porcine spinal cord peptides, designated neuromedin U-8 and neuromedin U-25. Protected neuromedin U-8 (8-residue peptide), prepared by condensation of two fragments, served as a C-terminal amino component for the synthesis of neuromedin U-25 (25-residue peptide). Onto this fragment, five peptide fragments were successively condensed by the azide procedure to construct the entire amino acid sequence of neuromedin U-25, a possible biosynthetic precursor of neuromedin U-8. All protecting groups were cleaved from protected neuromedin U-8 and neuromedin U-25 by 1 M trimethylsilyl trifluoromethanesulfonate-thioanisole in trifluoroacetic acid. The results were compared with those obtained by trifluoromethanesulfonic acid deprotection. In terms of contractile activity in rat uterus, neuromedin U-25 was twice as active as neuromedin U-8.

  在溶液合成两种猪脊髓多肽（分别为神经生长因子 U-8 和神经生长因子 U-25）的过程中，证明了新的去保护程序的实用性。通过缩合两个片段制备的受保护神经生长素 U-8（8 个残基的多肽）可作为合成神经生长素 U-25（25 个残基的多肽）的 C 端氨基成分。在这一片段上，用叠氮程序连续缩合了五个肽片段，从而构建了神经生长素 U-25 的整个氨基酸序列，它可能是神经生长素 U-8 的生物合成前体。在三氟乙酸中用 1 M 三甲基硅基三氟甲磺酸-硫代苯甲醚裂解了受保护的神经生长素 U-8 和神经生长素 U-25 上的所有保护基团。结果与三氟甲磺酸脱保护法的结果进行了比较。在大鼠子宫收缩活性方面，神经生长素 U-25 是神经生长素 U-8 的两倍。
