  摘要：

  均一化修饰的磷酸二酯或硫代磷酸酯寡核苷酸，包含2'-脱氧-2'-氟腺苷、-鸟苷、-尿苷和-胞苷，首次在此报道，当它们与RNA杂交时，表现出一致的叠加性稳定性提升，同时不会影响碱基配对的特异性。2'-脱氧-2'-氟修饰的寡核苷酸与RNA杂交的圆二色光谱表明，杂交双链呈现完全的A型构象。以磷酸二酯形式存在的2'-脱氧-2'-氟修饰的寡核苷酸对核酸酶不具抵抗力；然而，以硫代磷酸酯形式存在的修饰寡核苷酸则具有极高的核酸酶抗性，并且保留了对RNA靶标的卓越结合亲和力。2'-脱氧-2'-氟修饰对RNA-DNA双链的稳定化效果被证明优于2'-O-甲基核糖的替代。与均一化2'-脱氧-2'-氟修饰寡核苷酸形成的RNA杂交双链不支持HeLa细胞中RNase H活性；然而，将修饰引入到“嵌合”寡核苷酸中已被证明可以激活哺乳动物的RNase H。均一化修饰的2'-脱氧-2'-氟硫代磷酸酯寡核苷酸提供了反义分子，具有（1）对RNA靶标的高结合亲和力和选择性，以及（2）对核酸酶的稳定性。

  摘要：

  An efficient conversion from commercially available 2,6-diaminopurine-2',3',5'-tri-O-benzyl arabinoside to arabinosylguanine and its further transformation to 2'-deoxy-2'-fluoro-guanosine is outlined. This process has been used to produce more than one hundred grams of final product.

  Oligomeric compounds including oligoribonucleotides and oligoribonucleosides are provided that have subsequences of 2′-pentoribofuranosyl nucleosides that activate dsRNase. The oligoribonucleotides and oligoribonucleosides can include substituent groups for increasing binding affinity to complementary nucleic acid strand as well as substituent groups for increasing nuclease resistance. The oligomeric compounds are useful for diagnostics and other research purposes, for modulating the expression of a protein in organisms, and for the diagnosis, detection and treatment of other conditions susceptible to oligonucleotide therapeutics. Also included in the invention are mammalian ribonucleases, i.e., enzymes that degrade RNA, and substrates for such ribonucleases. Such a ribonuclease is referred to herein as a dsRNase, wherein “ds” indicates the RNase's specificity for certain double-stranded RNA substrates. The artificial substrates for the dsRNases described herein are useful in preparing affinity matrices for purifying mammalian ribonuclease as well as non-degradative RNA-binding proteins.
