  Pyrrolidino-DNA

  摘要：

  We synthesized pyrrolidino-C-nucleosides, incorporated them into oligodeoxynucleotides and investigated their pairing properties. The thermal duplex and triplex stabilities were measured. While triplex formation is destabilized in the case of pyrrolidino-pseudo-U and -T, pyrrolidino-pseudo-iso-C leads to an increase of the T-m value for third strand dissociation. Duplexes Lire destabilized with all pyrrolidino-C-nucleosides.

  摘要：

  [GRAPHICS]A novel method for the synthesis of pyrrolidine C-nucleosides has keen developed, The key step of the synthesis is the palladium(0)-mediated coupling of a disubstituted N-protected 2-pyrroline and 5-iodouracil.

  Pyrrolidino pseudo-C-nucleosides are isosteres of natural deoxynucleosides which are protonated at the pyrrolidino ring nitrogen under physiological conditions. As constituents of a triplex forming oligodeoxynucleotide (TFO), the positive charge is expected to stabilise DNA triple helices via electrostatic interactions with the phosphodiester backbone of the target DNA. We describe the synthesis of the pyrrolidino isocytidine pseudonucleoside and the corresponding phosphoramidite building block and its incorporation into TFOs. Such TFOs show substantially increased DNA affinity compared to unmodified oligodeoxynucleotides. The increase in affinity is shown to be due to the positive charge at the pyrrolidino subunit.

  吡咯烷假C-核苷是天然脱氧核苷的电子等排体，其在生理条件下在吡咯烷环氮处质子化。作为形成三链体的寡脱氧核苷酸 (TFO) 的组成部分，正电荷有望通过与目标 DNA 的磷酸二酯主链的静电相互作用来稳定 DNA 三螺旋。我们描述了吡咯烷异胞苷假核苷和相应的亚磷酰胺结构单元的合成以及将其掺入 TFO 中。与未修饰的寡脱氧核苷酸相比，此类 TFO 显示出显着增加的 DNA 亲和力。亲和力的增加被证明是由于吡咯烷亚基上的正电荷。
