protecting group for peptide synthesis was demonstrated. The synthesis of the chemotactic peptide For-Met-Leu-Phe-OH as well as the synthesis of Met-enkephalin using CAM ester as carboxyl terminal protection were performed. These esters showed good stability during acidolytic removal of BOC N-protecting group, during hydrogenolysis of Z N-protecting group and during removal of FMOC N-protecting group. CAM
证明了羧酰胺基甲基酯(CAM酯)作为用于肽合成的羧基保护基的用途。进行了趋化肽For-Met-Leu-Phe-OH的合成以及使用CAM酯作为羧基末端保护的Met-脑啡肽的合成。这些酯在酸解去除BOC N-保护基期间,Z N-保护基的氢解期间和FMOC N-保护基的去除期间显示出良好的稳定性。CAM酯可被NaOH 0.5 N或Na 2 CO 3迅速裂解。但是,当序列中存在天冬氨酸的β-苄基酯时,我们未能成功地选择性除去CAM酯。

An object of the present invention is to provide methods of discovering drugs effective for tough targets, which have conventionally been discovered only with difficulty. The present invention relates to novel methods for cyclizing peptide compounds, and novel peptide compounds and libraries comprising the same, to achieve the above object.
