The specification describes the total synthesis of L-norleucine-13-motilin ased 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.
该规范描述了L-正异亮氨酸-13-莫替林的全合成,其基于将位于13位的L-甲硫氨酸基团替换为L-正异亮氨酸基团。根据当前肽合成的发展,莫替林的中心精氨酰-甲硫氨酰键(氨基酸12和13)在实践中几乎无法合成,而与之相反,对应于莫替林的正异亮氨酸-13-二十二肽可以更容易地进行合成,这为结构的比较快速的确定提供了可能,同时也可以提供有关甲硫氨酸生物效应特异性的重要信息。
