与 水淬 相关的网络例句 [注:此内容来源于网络,仅供参考]

The present invention relates to a process for rapid solution synthesis of a peptide, the process comprising repetitive cycles of steps-: a coupling step, using an excess of an activated carboxylic component to acylate an amino component, a quenching step in which a scavenger is used to remove residual activated carboxylic functions, wherein the scavenger may also be used for deprotection of the growing peptide, one or more aqueous extractions and optionally, a separate deprotection step, followed by one or more aqueous extractions, characterised in that the process comprises at least one step, referred to as step, in which an amine or a thiol comprising a free anion or a latent anion is used as a scavenger of residual activated carboxylic functions.

本发明涉及快速溶液合成肽的方法,该方法包括步骤-的重复循环:偶联步骤,使用过量的活化羧基成分酰化氨基成分,淬灭步骤,在该步骤中使用清除剂除去残余的活化羧基官能团,其中该清除剂还可以用于使生长中的肽去保护,一或多个水抽提和任选地,独立的去保护步骤,之后进行一或多次水抽提,其特征在于该方法包括至少一个步骤,称作步骤,在该步骤中包含自由阴离子或潜阴离子的胺或硫醇用作残余活化羧基官能团的清除剂。
