2-Nitrobenzylamino-type anchoring groups were incorporated on 2% butanediol dimethacrylate cross-linked polystyrene support. The resultant photolabile polymeric supports were used for the synthesis of fully protected peptides and their final cleavage as C-terminal peptide acids, peptide amides and peptide N-alkyl amides by photolysis under mild neutral conditions. The photosensitive chromophore has
将2-硝基苄基氨基型锚定基团结合在2%丁二醇二甲基丙烯酸酯交联的聚苯乙烯载体上。所得的对光不稳定的聚合物载体用于合成完全保护的肽,并最终裂解为C端肽酸,肽酰胺和肽N-烷基酰胺在温和的中性条件下光解。光敏发色团具有双重功能,即在支持物和生长中的肽链之间起锚定键的作用,并在光解裂解过程中用作将C末端羧基转化为修饰形式的潜在试剂。通过在TFE / DCM混合物中以350 nm照射肽基树脂获得C末端修饰的肽。通过以非常高的产率和纯度合成肽的保护的衍生物来说明新树脂的功效。通过氨基酸分析,TLC和MALDI TOF MS检查肽的身份。
