已经开发了一种基于氧硫杂磷烷化学合成肽-寡核苷酸偶联物 (POC) 的新方法。分别制备的肽和寡核苷酸片段通过肽的官能化在合成后连接,通过将氧硫杂磷杂环戊烷残基直接连接在 N 末端或连接到 N 末端的接头的羟基进行连接。基于 DBU 辅助的寡核苷酸羟基对肽氧硫杂磷烷衍生物中磷原子的亲核攻击,共轭反应提供了所需的 POC。

A novel approach to the synthesis of peptide-oligonucleotideconjugates (POC) based on the oxathiaphospholane chemistry has been developed. Peptide and oligonucleotide fragments, which were separately prepared, were linked postsynthetically by the functionalization of the peptide either by attachment of the oxathiaphospholane residue directly at the N-terminus or at the hydroxy group of the linker
