  C2′-Pyrene-Functionalized Triazole-Linked DNA: Universal DNA/RNA Hybridization Probes

  摘要：

  Development of universal hybridization probes, that is, oligonudeotides displaying identical affinity toward matched and mismatched DNA/RNA targets, has been a longstanding goal due to potential applications as degenerate PCR primers and microarray probes. The classic approach toward this end has been the use of "universal bases" that either are based on hydrogen-bonding purine derivatives or aromatic base analogues without hydrogen-bonding capabilities. However, development of probes that result in truly universal hybridization without compromising duplex thermostability has proven challenging. Here we have used the "click reaction" to synthesize four C2'-pyrenefunctionalized triazole-linked 2'-deoxyuridine phosphoramidites. We demonstrate that oligodeoxyribonucleotides modified with the corresponding monomers display (a) minimally decreased thermal affinity toward DNA/RNA complements relative to reference strands, (b) highly robust universal hybridization characteristics (average differences in thermal denaturation temperatures of matched vs mismatched duplexes involving monomer W are <1.7 degrees C), and (c) exceptional affinity toward DNA targets containing abasic sites opposite of the modification site (Delta T-m up to +25 degrees C). The latter observation, along with results from absorption and fluorescence spectroscopy, suggests that the pyrene moiety is intercalating into the duplex whereby the opposing nucleotide is pushed into an extrahelical position. These properties render C2'-pyrene-functionalized triazole-linked DNA as promising universal hybridization probes for applications in nucleic acid chemistry and biotechnology.

  三种P修饰的核苷酸：合成及其对二级核酸结构的影响

  摘要：

  使用CuAAC反应可完成三种pyr修饰的核苷的合成。因此，pyr通过三唑基亚甲基连接基连接到胸苷的5'-位置或2'-脱氧尿苷的2'-位置，或通过更刚性的三唑连接基连接到2'-脱氧尿苷的2'-位置。将三个核苷掺入寡核苷酸中，并将它们组合成不同的双链体和其他二级结构，并通过热稳定性和荧光研究对其进行分析。发现这三种单体对核酸复合物具有不同的影响。因此，如荧光强度的总体下降和随后双链体热稳定性的提高所表明的，连接至5'-位的pyr显示出插入双链体的趋势。通过刚性三唑连接基连接到2'-位的也显示插入的趋势，但双链稳定性降低，而通过三唑亚甲基连接基连接到2'-位的pyr主要位于小槽中，如荧光的增加，但在大多数情况下会导致双链体稳定性的增加。所有三个pyr核苷酸导致凸起的双链体和三向连接的热稳定。在某些情况下，当将两个pyr引入这些复合物的核心时，荧光准分子带的形成或消失可用于指示杂交过程。因此，这些

  Disclosed embodiments concern a probe comprising one or more pairs of monomers capable of targeting a nucleic acid target. The pair of monomers may be arranged in a manner that promotes thermoinstability of the probe complex, thus producing a probe capable of locating and/or detecting a target. The probe also may comprise one or more natural or non-natural nucleotides capable of Watson-Crick base pairing with an isosequential nucleic acid target. Particular disclosed embodiments concern a method of using the disclosed probe to target nucleic acids. In particular disclosed embodiments, the probe may be incubated with a target nucleic acid and then be detected.

  Synthesis of three pyrene-modified nucleosides was accomplished using the CuAAC reaction. Hereby, pyrene is attached either to the 5′-position of thymidine or to the 2′-position of 2′-deoxyuridine through triazolemethylene linkers, or to the 2′-position of 2′-deoxyuridine through a more rigid triazole linker. The three nucleosides were incorporated into oligonucleotides, and these were combined in
