de (ODN) analogs to be used in biotechnological applications, we report here the synthesis, characterization and nucleic acid binding studies of novel nucleopeptides, that we called ε-lys/γ-dabPNAs, containing a backbone of alternated l-diaminobutyric acid and l-lysine moieties. Exploring the hybridization properties of the new ODN analog, we found, by circular dichroism and UV spectroscopies, that
为了开发用于生物技术应用的新的寡脱氧核糖核苷酸(ODN)类似物,我们在此报告了新型核苷酸肽的合成,表征和核酸结合研究,我们称其为ε-lys / γ- dabPNA,其中包含交替骨架1-二氨基丁酸和1-赖氨酸部分。通过圆二色性和紫外分光光度法研究了新型ODN类似物的杂交特性,发现高纯胸腺嘧啶ε-lys / γ-dabPNA六聚体结合互补序列的DNA和RNA。此外,对替代核苷酸肽的人血清稳定性测定证明了显着的降解抗性。这些结果鼓励我们加深对该类似物的了解,以评估其在抗原/反义或诊断应用中的可能用途。
