Abstract
We present procedures for nucleoside and oligonucleotide synthesis, binding affinity (Tm) and structural analysis (CD spectra) of 2'-deoxy-2',2''-difluoro-alpha-D-ribofuranosyl and 2'-deoxy-2',2''-difluoro-beta-D-ribofuranosyl oligothymidylates. Possible reasons for the thermal instability of duplexes formed between these compounds and RNA or DNA targets are discussed.
摘要
我们展示了2'-脱氧-2',2''-二氟-α-D-呋喃核糖基和2'-脱氧-2',2''-二氟-β-D-呋喃核糖基寡聚胸苷酸的核苷和寡核苷酸合成、结合亲和力（熔解温度）及结构分析（圆二色光谱）的方法。讨论了这些化合物与RNA或DNA靶标形成的双链体热不稳定性的可能原因。
