We previously reported an efficient peptide synthesis method, AJIPHASE®, that comprises repeated reactions and isolations by precipitation. This method utilizes an anchor molecule with long-chain alkyl groups as a protecting group for the C-terminus. To further improve this method, we developed a one-pot synthesis of a peptide sequence wherein the synthetic intermediates were isolated by solvent extraction
我们先前报道了一种有效的肽合成方法AJIPHASE®,该方法包括重复的反应和通过沉淀分离。该方法利用具有长链烷基的锚分子作为C末端的保护基。为了进一步改进该方法,我们开发了一种肽序列的一锅法合成方法,其中合成中间体通过溶剂萃取而不是沉淀法进行分离。在新工艺中使用了支链锚分子,与以前的方法相比,该方法显着提高了长肽的溶解度和操作效率,而以前的方法采用沉淀法进行分离和使用直链脂族基团。这种基于溶剂萃取的策略的另一个先决条件是使用硫代苹果酸和DBU进行Fmoc脱保护,
