  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.

  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.
