专利号:US-3978035-A 优先权日:1973-03-27 标 题 :13-Norleucine-14-desamido motilin, a method for preparing it and an agent containing it 发明人:WUNSCH ERICH; WENDLBERGER GERHARD; JAEGER ERNST; SCHARF REGINE; DEIMER KARL-HEINZ; STOCKER HANS 权利人:MAX PLANCK GESELLSCHAFT 摘要:The specification describes the total synthesis of L-norleucine-13-motilinased on the replacement of the L-methionine radical located in the 13-position by an L-norleucine radical. In accordance with the present day development of peptide synthesis the central arginyl-methionyl-bond (amino acids 12 and 13 of motilin) can in practice hardly be synthesised, while on the other hand the norleucine-13-docosapeptide corresponding to motilin can be more readily produced synthetically, and this provides for a comparatively rapid determination of structure and can give important information as regards the biological effect specificity of methionine.
