  Synthesis and Hybridization Properties of Oligonucleotides Containing Polyamines at the C-2 Position of Purines: A Pre-synthetic Approach for the Incorporation of Spermine into Oligodeoxynucleotides Containing 2-(4,9,13-Triazatridecyl)-2′-deoxyguanosine

  摘要：

  We have developed a synthesis of spermine-containing oligonucleotides (ODN-sper) which allows incorporation of multiple polyamine residues. This approach was based on the pertrifluoroacetylated 5'DMT-dGsper phosphoramidite synthon. Its coupling yield with resin-bound ODN decreased dramatically when close to the 3'-end. Optimization of the coupling conditions allowed 22-mer ODNs containing up to six spermine residues to be synthesized. Several ODNs of different sequences with 1-4 pendent spermines could be purified and their hybridization properties were evaluated. Duplex melting temperatures increased linearly with the number of polyamine.residues (DeltaT(m)/sper = 3.0 +/- 0.2 degreesC in 100 mM NaCl). This compares very favorably with values reported for duplexes of similar initial stability containing other cation-substituted bases. Moreover, the stability increase was neither sequence nor position-dependent, and even contiguous spermine residues did not crosstalk. Extrapolation based on these findings leads to the conclusion that a duplex formed with a 22-mer oligonucleotide containing seven spermine residues would be as stable as genomic DNA, which highlights its potential for DNA strand invasion.

  吡咯衍生的双功能亲电试剂的 DNA 链间交联反应：DNA 中共同靶位点的证据

  摘要：

  由吡咯衍生的双功能亲电试剂家族鉴定的 DNA 链间交联位点在合成 DNA 双链体中进行了体外研究。该家族包括还原活化的丝裂霉素 C (1)、氧化活化的吡咯里西啶生物碱（例如 2）、简单的吡咯 2,3- 和 3,4-双-（乙酰氧基甲基）-1-甲基吡咯（3 和 4），以及抗肿瘤剂物质 2,3-二氢-5-(3',4'-二氯苯基)-6,7-双(羟甲基)-1H-吡咯嗪双-(异丙基氨基甲酸酯) (IPP, 5)。本文证明这些试剂优先交联双链 DNA 中的共同靶位点，即序列 5'-d(CG) 处脱氧鸟苷残基的环外氨基

• Stable and Selective Antiparallel Type Triplex DNA Formation by Targeting a GC Base Pair with the TFO Containing One &lt;i&gt;N&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt;-Phenyl-2′-deoxyguanosine

  osine (PhdG) showed a stable and selective triplex DNA formation with the GC base pair as compared to the natural dG/GC triplet. However, the multiple incorporation of PhdG into the TFOs hampered the stable triplex DNA, instead, showed a tendency to form a higher order structure. Therefore, we concluded that the stable and selective triplex DNA formation is expected by the replacement of dG by PhdG

  反平行三链体DNA是由富含嘌呤的三链体形成寡核苷酸（TFO）与双链体DNA中的同嘌呤区之间的相互作用形成的。这种具有基因组DNA的结构的形成有望控制活细胞中的基因表达。在这项研究中，为了增强三链DNA的稳定性，我们设计了N2-芳基化的脱氧鸟苷衍生物。在这些类似物中，我们发现与天然dG / GC三联体相比，含有N2-苯基-2'-脱氧鸟苷（PhdG）的TFO具有稳定的，选择性的三联DNA形成，并带有GC碱基对。但是，将PhdG多次掺入TFO阻碍了稳定的三链DNA，相反，它倾向于形成更高阶的结构。所以，

  N2‐Alkyl‐2′‐deoxyguanosine triphosphate (N2‐alkyl‐dGTP) derivatives with methyl, butyl, benzyl, or 4‐ethynylbenzyl substituents were prepared and tested as substrates for human DNA polymerases. N2‐Benzyl‐dGTP was equal to dGTP as a substrate for DNA polymerase κ (pol κ), but was a poor substrate for pols β, δ, η, ι, or ν. In vivo reactivity was evaluated through incubation of N2‐4‐ethynylbenzyl‐dG

  An improved synthesis of the deoxy-2-fluoroinosine nucleoside is described, that makes use of mild fluorination (polyvinylpyridinium polyhydrogenfluoride) and O-silyl deprotection (triethylamine trihydrofluoride) reactions. The derived 5'-dimethoxytrityl-2-fluoroinosine-3'-phosphoramidite was incorporated into 10-, 15- and 20- mer oligonucleotides containing up to 7 non-natural bases.
