Novel oligonucleotide dimers containing hydroxamate linkages (15 and 16) were synthesized, incorporated into oligonucleotide sequences and studied for their hybridization properties with complementary DNA and RNA targets. The modified oligonucleotides showed similar binding properties and enhanced resistance to exonucleases compared to natural oligonucleotides.
合成了包含异羟肟酸酯键(15和16)的新型寡核苷酸二聚体,将其掺入寡核苷酸序列中,并研究了它们与互补DNA和RNA靶标的杂交特性。与天然寡核苷酸相比,修饰的寡核苷酸显示出相似的结合特性并增强了对核酸外切酶的抗性。
