isothiocyanate derivatives of commercial functional molecules to give target functionalized PNA monomer units 25–53. Various types of functionalized PNA monomer units could be efficiently incorporated into multiple predetermined positions in a PNA oligomer by SPPS (solid phase peptide synthesis) in the same way as for the four A(Cbz), G(Cbz), C(Cbz), and T PNA monomer units.
描述了一种用于官能化PNA(肽核酸)的新颖有效的合成方法,其中结合了功能性分子代替核碱基。新颖ω-AA-的Boc PNA-OH(20 - 24,AA =氨基酸)被设计为PNA前体引入该功能分子可有效地结合的单体单元。化合物20 - 24与OSu的(定量反应Ñ -hydroxysuccinimidyl)活性酯衍生物和商业功能分子的异硫氰酸酯衍生物,得到目标官能PNA单体单元25 - 53。可以通过SPPS(固相肽合成)以与四个A(Cbz),G(Cbz),C(Cbz),和T PNA单体单元。
