Abstract

The invention discloses a preparation method of solid phase peptide synthesis atosiban which includes the following steps: taking Rink Amide resins, Rink Amide MBHA resins or Rink Amide AM resins as starting materials and taking Fmoc amino acids as monomers, amino acids are grafted one by one and mercaptopropionic acids (Map(SX)) are protected by the last peptide chain; after protected nonapeptide resins are obtained, the acellular side-chain protective groups and cutting peptides are synchronized; then cutting peptides is carried out, and reduced crude atosiban is collected; the pH value is adjusted to 7.5 to 10.0, and oxidized crude atosiban is collected; target products are obtained by the separation and purification by preparative HPLC(C18 or C8 column). The preparation method is convenient in material source, simplifies technology and reduces cost; and the preparation method is low in the pollution of three wastes and is high in yield, and the preparation method is convenient for being industrialized and has good industrialization prospect.

Description

technical field

[0001] The invention relates to a preparation method of atosi-like, in particular to a preparation method of solid-phase polypeptide synthesis of atosi-like. Background technique

[0002] Chinese name: Atosiban, Atosiban acetate, Atosiban, Atosiban acetate.

[0003] English name: Atosiban, Atosiban Acetate.

[0004] The structural formula is:

[0005]

[0006] The molecular formula is: C 43 h 67 N 11 o 12 S 2

[0007] Molecular weight: 994.2

[0008] Atosi is generally clinically a cyclic peptide oxytocin competitive antagonist that can be injected intravenously on receptors in the uterus, decidua, and fetal membranes. After using this product, it can inhibit uterine contractions in a dose-related manner, and reduce the secretion of prostaglandins mediated by the cyclic peptide oxytocin, so as to achieve the purpose of fetal protection. It can be used for people over 18 years old, with a gestational age of 24-33 weeks, and a normal fetal heart rat...
