摘要

Process for preparing peptides that have influence on the function of the pituitary gland.Comprising: (a) make Short peptides or amino acids together to form an intermediate Compound of formula (ii), which is a protecting Group; (b) Splitting the Protecting groups or the link of Anchoring Peptide of formula (ii), treating the compound with HF, 0jc, to obtain the peptid Or of formula (i); and (c) convert the Peptide, resulting in an addition of non-toxic Salt thereof.Being: r40k Wing, or desr40 carboxyl portion; and The residue of the c-terminal amino acid; x1 to X7, x8 H or Protective Group and protective Group, the Resin Anchor bracket or des X8, in whose Case The residue in the c-terminal carboxyl and has a portion that is used for promo. See the release of growth hormone by the pituitary gland in Mammals.
