chemistry using solid phase synthesis, there is a great deal of interest in developing new solid phase linkers, which are stable during the solid phase synthesis process and yet readily cleavable under mild conditions. By taking advantage of a "trimethyl lock"-facilitated lactonization reaction, we have developed a redox-sensitive resin linker for the synthesis of C-terminal-modified peptides. The cleavage
随着使用固相合成的组合化学的迅速发展,人们对开发新的固相连接物有极大的兴趣,这些固相连接物在固相合成过程中稳定并且在温和条件下易于裂解。通过利用“三甲基锁”促进的内酯化反应,我们开发了一种氧化还原敏感性树脂接头,用于合成C末端修饰的肽。裂解仅需要温和的还原剂,例如亚硫酸氢钠,预计不会对常见的有机官能团造成任何问题。使用这个新的接头,合成了三个短肽,分离率高(70-90%)。这样的接头可潜在地用于合成修饰的肽文库,
