This application discloses nucleoside analogs that when incorporated into a oligonucleotide, forms a nucleobase pair with either thymidine or cytidine that are present in a complementary strand at the paired position. These analogs are called “purine biversals”. Such compounds and their associated processes have utility in processes that detect complementary oligonucleotides, in particular oligonucleotides from natural sources and in complex biological mixtures, where the sequence of the complementary oligonucleotide being detected is not known precisely. The invention also includes compositions of matter that are oligonucleotides that contain purine biversals of the instant invention, and duplexes of said oligonucleotides.
该应用程序披露了一种核苷类似物,当其嵌入到寡核苷酸中时,与配对位置上互补链中的胸腺
嘧啶或
胞嘧啶形成核碱基对。这些类似物被称为“
嘌呤双向体”。这种化合物及其相关过程在检测互补寡核苷酸的过程中具有实用性,特别是在来自自然来源和复杂
生物混合物中的寡核苷酸,其中被检测的互补寡核苷酸的序列并不精确已知。该发明还包括含有本发明的
嘌呤双向体的寡核苷酸的物质组合物,以及所述寡核苷酸的双链。
