Nucleic acid probe, method for designing nucleic acid probe, and method for detecting target sequence
-
, (2018/02/28)
The present invention provides a nucleic acid probe that can achieve high detection sensitivity and high specificity in mutation detection, mismatch detection, etc. by the PCR method, a method for designing such a nucleic acid probe, and a method for detecting a target sequence. The nucleic acid probe includes a nucleic acid molecule, and the nucleic acid molecule includes a plurality of fluorescent dye moieties that exhibit an excitonic effect. At least two of the fluorescent dye moieties that exhibit an excitonic effect are bound to the same base or two adjacent bases in the nucleic acid molecule with each fluorescent dye moiety being bound via a linker (a linking atom or a linking atomic group). The extension-side end of the nucleic acid molecule is chemically modified, thereby preventing an extension reaction of the nucleic acid molecule.

Nucleosides represent a major chemotherapeutic class for treating cancer, however their limitations in terms of cellular uptake, nucleoside kinase-mediated activation and catabolism are well-documented. The monophosphate pro-nucleotides known as ProTides represents a powerful strategy for bypassing the dependence on active transport and nucleoside kinase-mediated activation. Herein, we report the structural tuning of BVdU ProTides. Forty six phosphoramidates were prepared and biologically evaluated against three different cancer cell lines; murine leukemia (L1210), human CD4+T-lymphocyte (CEM) and human cervical carcinoma (HeLa). Twenty-fold potency enhancement compared to BVdU was achieved against L1210 cells. Interestingly, a number of ProTides showed low micromolar activity against CEM and HeLa cells compared to the inactive parent BVdU. The ProTides showed poor, if any measurable toxicity to non-tumourigenic human lung fibroblast cell cultures. Separation of four pairs of the diastereoisomeric mixtures and comparison of their spectral properties, biological activities and enzymatic activation rate is reported.

Pd-imidate complexes have been employed as efficient catalysts for the Heck alkenylation of unprotected 5-iodo-2′-deoxyuridine in acetonitrile. The protocol was also shown to work well for the unprotected 5-iodo-2′-deoxycytidine. A highly efficient scale-up synthesis of the HSV-1 inhibitor Brivudine (BVDU) is also accomplished in an overall yield of 72% over 3-steps. The catalyst also showed recyclability for 3 consecutive runs.

Nucleoside analogues are extensively used in the treatment of cancer and viral diseases. The antiproliferative properties of organorhenium(I) complexes, however, have been scarcely explored to date. Herein we present the syntheses, characterization, and in vitro evaluation of ReI(CO)3 core complexes of thymidine and uridine. For the binding of the Re I(CO)3 core, a tridentate dipicolylamine metal chelate was introduced at positions C5′, C2′, N3, and C5 with spacers of various lengths. The corresponding organometallic thymidine complexes were fully characterized by IR and NMR spectroscopy and mass spectrometry. Their cytotoxicity was assessed against the A549 lung carcinoma cell line. Toxicity is dependent on the site and mode of conjugation as well as on the nature and the length of the tether. Moderate toxicity was observed for conjugates carrying the rhenium moiety at position C5′ or N3 (IC50=124-160 μm). No toxicity was observed for complexes modified at C2′ or C5. Complex 53, with a dodecylene spacer at C5′, exhibits remarkable toxicity and is more potent than cisplatin, with an IC50 value of 6.0 μm. To the best of our knowledge, this is the first report of the antiproliferative properties of [M(CO)3]+1-nucleoside conjugates. In competitive inhibition experiments with A549 cell lysates and purified recombinant human thymidine kinase 1 (hTK-1), enzyme inhibition was observed for complexes modified at either N3 or C5′, but our results suggest that the toxicity cannot be attributed solely to interaction with hTK-1.

The present invention provides a primer that effectively can detect, for example, the double helix structure of a nucleic acid. The primer is a labeled nucleic acid containing at least one structure represented by the following formula (16), where B is an atomic group having a nucleobase skeleton, E is an atomic group having a deoxyribose skeleton, a ribose skeleton, or a structure derived from either one of them, or an atomic group having a peptide structure or a peptoid structure, and Z11 and Z12 are each an atomic group that exhibits fluorescence and are identical to or different from each other.

We describe a light-controlled template-directed reversible DNA photoligation via carbazole-tethered 5-carboxyvinyluracil. Carbazole-tethered 5-carboxyvinyl-2'-deoxyuridine-containing oligodeoxynucleotide (ODN) can be ligated by irradiation at 366 nm in the presence of template ODN, and the ligated ODN can be split by irradiation at 366 nm in the absence of template ODN.

Phosphoramidate derivatives of nucleotides and their use in the treatment of cancer are described. The base moieties of, for example, each of deoxyuridine, cytarabine, gemcitabine and citidine may be substituted at the 5-position. The phosphoramidate moiety has attached to the P atom an aryl-O moiety and an α-amino acid moiety. The α-amino acid moiety may correspond to or be derived from either a naturally occurring or a non-naturally occurring amino acid.
