Abstract A series of eleven 5-substituted-indole nucleoside residues were synthesized and incorporated into 15-mer oligodeoxynucleotide duplexes with each of the four natural bases (A, G, C, T) paired with the non-natural residues. The universal base properties of these residues were evaluated by comparing the stabilities of these complexes determined by UV thermal denaturation experiments. All of
摘要 合成了一系列 11 个 5 取代的吲哚核苷残基,并将其掺入 15 聚体寡脱氧核苷酸双链体中,其中四种天然碱基(A、G、C、T)中的每一个都与非天然残基配对。通过比较由紫外热变性实验确定的这些复合物的稳定性,评估了这些残基的通用碱基特性。所有取代的吲哚比未取代的吲哚残基更稳定,并且取代基对吲哚π体系的电子影响的测量与稳定性相关。几个残基比先前研究的 5-硝基吲哚残基更混杂,但取代基和选择性之间的关系尚不清楚。
