Synthesis of an oligonucleotide containing one methylphosphonate locked nucleic acid (LNA) thymine monomer using the phosphoramidite approach is described. The binding affinity of this 9-mer methylphosphonate LNA towards complementary DNA and RNA oligonucleotides was increased compared to the reference DNA, but decreased compared to the reference LNA. In the 9-mer sequence context studied, introduction
描述了使用亚磷酰胺方法合成包含一种甲基膦酸酯锁定的核酸(LNA)胸腺嘧啶单体的寡核苷酸。与参考DNA相比,该9聚体甲基膦酸酯LNA对互补DNA和RNA寡核苷酸的结合亲和力增加,但与参考LNA相比降低。在研究的9-mer序列背景下,与单个LNA单体相反,引入单个甲基膦酸LNA单体可有效抑制3'-外切核酸降解。
