摘要:
核酸和核酸-蛋白质复合物的硒衍生化为解决 X 射线晶体学中的相位问题提供了强有力的工具。核苷酸中的硒原子可以作为晶体衍射中的精细散射中心。为了合成含有多个硒原子的核苷酸,为晶体结构测定提供强大的相位能力,我们在此报告了在一个核碱基中含有两个硒原子的胸苷类似物的合成。合成的新型含硒核苷酸和寡核苷酸 DNA 具有红移紫外光谱和黄色。它们的独特性质有助于相位测定、核酸检测以及核酸和核酸-蛋白质复合物的光谱研究。

Synthesis of di-2-cyanoethyl diselenide is reported for the first time. Using this reagent, incorporation and protection of selenium functionality can be achieved in one step with high yield, and the deprotection condition is mild, which allows alkylation simultaneously.

The selenium derivatization of nucleic acids and nucleic acid-protein complexes has provided a powerful tool to solve phase problem in X-ray crystallography. Selenium atoms in the nucleotides can serve as fine scattering centers in crystal diffraction. Towards the synthesis of multiple selenium atom-containing nucleotides, which offers strong phasing power to facilitate crystal structure determination, we report here the synthesis of the thymidine analogue containing two Se atoms in one nucleobase. The novel Se-containing nucleoside and oligonucleotide DNAs were synthesized and found with the red-shifted UV spectrum and yellow color. Their unique properties are useful in phase determination, nucleic acid-based detection as well as spectroscopic studies of nucleic acids and nucleic acid-protein complexes.
