Four double-headed nucleosides were prepared by the CuAAC reaction. Hereby, a triazole-containing linker connects an additional thymine or adenine to the 2′-position of 2′-deoxyuridine, a thymine to the 5′-position of thymidine and a thymine to the 6′-position of an LNA-thymidine monomer. Whereas no conclusive recognition effects of the additional thymines were found when introduced in LNA or at the
通过CuAAC反应制备了四个双头核苷。因此,含三唑的连接基连接额外的胸腺嘧啶或腺嘌呤 到的2'位置 2'-脱氧尿苷,胸腺嘧啶在5'- 胸苷和胸腺嘧啶在LNA-胸苷单体的6'-位。引入LNA或5'位置时,未发现其他胸腺嘧啶的结论性识别作用,两者胸腺嘧啶 和 腺嘌呤 当特别引入所谓的(+1)拉链基序时,发现2'位置的dDNA可以稳定dsDNA和DNA:RNA上下文中的三向连接,并在DNA双链体中产生交叉链相互作用。 。
