A novel triazole linkage that mimics the phosphodiester backbone in DNA was designed, synthesised and evaluated. Unlike previous work which utilised copper to form a 1,4 triazole linkage in the DNA backbone, a ruthenium catalyst was used to yield a 1,5 triazole. The artificial linkage was incorporated into a DNA backbone via a phosphoramidite building block using solid phase synthesis. The biophysical properties of DNA with a 1,5 triazole linkage in the backbone were evaluated by UV melting and circular dichroism and compared to DNA modified with previously reported 1,4 triazole linkages of various lengths.

寻找理想的三唑:研究1,5-三唑作为电荷中性的DNA主链模拟物
设计,合成和评估模拟DNA中的磷酸二酯主链的新型三唑键。与以前的利用铜在DNA主链中形成1,4三唑键的工作不同,钌催化剂用于产生1,5三唑。使用固相合成,通过亚磷酰胺构件将人工连接结合到DNA主链中。通过紫外熔融和圆二色性评估骨架中具有1,5三唑键的DNA的生物物理特性,并将其与先前报道的各种长度的1,4三唑键修饰的DNA进行比较。
