A new class of backbone-modified oligonucleotide analogs has emerged since the discovery of the Cu I -catalyzed [3+2] azide/alkyne cycloaddition reaction. These are oligonucleotide analogs with 1,4-disubstituted 1,2,3-triazoles as the internucleotide linkages. Of all such analogs known, only the triazole-linked deoxythymidine decamer [(dT)10] has been reported to show enhanced binding affinity to complementary
自从发现 Cu I 催化的 [3+2] 叠氮化物/炔环加成反应以来,出现了一类新的骨架修饰的寡核苷酸类似物。这些是具有 1,4-二取代的 1,2,3-三唑作为核苷酸间键的寡核苷酸类似物。在所有已知的类似物中,只有三唑连接的脱氧胸苷十聚体 [(dT)10] 被报道显示出与互补 DNA 的结合亲和力增强。重要的是,它是一个完全修改的 (dT)10 模拟。迄今为止,尚未描述具有相同骨架修饰的顺序异质寡核苷酸。以研究序列和规律为目的
