    Oxygen Replacement with Selenium at the Thymidine 4-Position for the Se Base Pairing and Crystal Structure Studies
    摘要:
    The T-A and C-G base pairing and stacking allow the formation of the stable DNA duplex structure for genetic information storage, transcription, and replication. To replace the oxygen of the nucleotide nucleobases with selenium for the studies of the base-pair recognition, the duplex stability, and the nuclei acid crystal structures, we have synthesized for the first time the 4-Se thymidine phosphoramidite and incorporated it into oligonucleotides via solid-phase synthesis with high coupling yield (99%). The Se modification on the nucleobase is relatively stable under the elevated temperature. Using the dU(Se) (2'-Se-dU) to facilitate the crystallization, we have successfully crystallized the DNA containing the 4-Se-T substitution and determined its structure at 1.50 A resolution. The UV-melting and X-ray crystal structure studies have indicated that the Se substitution on the nucleobase does not cause a significant structure perturbation, the large Se atom on the thymine can be successfully accommodated by the DNA duplex, and the Se-mediated hydrogen bond (longer than the usual hydrogen bond) is formed within the modified T-A base pair. In addition, the Se derivatization on the nucleobases further facilitates X-ray crystal structure determination of nucleic acids and their protein complexes via Se MAD phasing.

    可逆的二硒化物交联在含有2'-脱氧-6-硒代肌苷的寡核苷酸之间形成
    摘要:
    我们已经合成并表征了2'-脱氧-6-硒代肌苷的亚磷酰胺衍生物(d 6Se I),并通过固相合成将该修饰结合到寡核苷酸中。在从固相支持物切割和脱保护期间,该寡核苷酸的自发二聚化是通过在修饰的核碱基之间形成二硒化物交联而发生的。该交联可以容易地还原以恢复单链寡核苷酸。d 6Se的双链体的紫外热变性和圆二色谱我对所有四个天然核苷碱基配对发现,相对于2'-脱氧肌苷,在稳定性和结构上存在微小差异。这种含硒的核碱基修饰可能可用于DNA纳米材料和X射线晶体学。

  • Unexpected Formation of <i>ortho</i>-Benzoquinone-fused Tetraselenafulvalene (TSF): Synthesis, Structures, and Properties of a Novel TSF-based Donor–Acceptor Dyad
    作者:Akira Ueda、Hiromichi Kamo、Hatsumi Mori
    DOI:10.1246/cl.150701
    日期:2015.11.5
    Electrochemical oxidation of a catechol-fused tetraselenafulvalene (TSF) derivative unexpectedly gave its ortho-benzoquinone analogue, in contrast to the tetrathiafulvalene (TTF) system that afforded a hydrogen-bonded organic conductor. The obtained donor–acceptor dyad showed amphoteric redox character, a small HOMO–LUMO gap, effective intermolecular interactions, and NIR absorption.

    日期:2007.11.1
    Se-(2-cyanoethyl)phthalimide was synthesized from di-(2-cyanoethyl) diselenide. This reagent was found to be an efficient selenium transfer reagent in the synthesis of selenophosphates. Thus, nucleotide H-phosphonate diesters that are formed in situ through the H-phosphonate chemistry undergo quantitative reaction with Se-(2-cyanoethyl)phthalamide. The resulting Se-(2-cyanoethyl) oligonucleotide phosphoroselenoate

    日期:2011.4.15
    The synthesis of the 5′-Se-derivatized thymidine and phosphoramidite is reported, and the Se-phosphoramidite was incorporated into DNA. Because of its high nucleophilicity, this 5′-Se-moiety permits convenient postsynthetic modification of oligonucleotides. The proof of principle was successfully demonstrated by incorporating fluorescein into DNA. It was also found that the 5′-dye-labeled Se-DNA can
