  Chemical synthesis and characterization of duplex DNA containing a new base pair: a nondisruptive, benzofused pyrimidine analog

  摘要：

  A new base pair appropriate for incorporation into B-DNA was designed with the goal of allowing fusion of a benzene substituent across the 4 and 5 carbons of a pyrimidine analog. Such a residue may have utility in the preparation of DNA duplexes bearing precisely spatially positioned and conformationally constrained unnatural substituents such as reporter groups. The design called for the incorporation of the beta-anomer of a C-linked deoxyriboside of 2-hydroxyquinoline (dQ) opposite the beta-N9 deoxyriboside of 2-aminopurine (dAP). Several duplex DNAs were synthesized containing this new base pair as well as the analog in which 2-hydroxypyridine replaces 2-hydroxyquinoline (dP). Phosphoramidites 17 and 18 were synthesized and incorporated into synthetic oligonucleotides using automated methodology. That dQ and dP had been incorporated without chemical modification was proven by enzymatic digestion of the synthetic oligonucleotides to the component nucleosides and analysis by HPLC. Native polyacrylamide gel electrophoresis revealed that admixture of complementary strands containing dP or dQ opposite dAP gave new substances with mobility comparable to a duplex DNA of the same length containing only Watson-Crick base pairs. Solution circular dichroism measurements were consistent with these substances existing in the B conformation. T(m), DELTAH, and DELTAS were measured for synthetic duplex DNAs containing pairings of dQ and dP with dAP, dA, dC, dG, and dT. Of these, duplexes in which dAP was the partner of dP or dQ were most thermodynamically stable (DELTAG 25-degrees-C) and highest melting, with T(m) values lower by 1 to 5-degrees-C than the corresponding dA.dT-containing duplex. Solution H-1 NMR measurements from delta 11-15 on an 11-mer duplex containing the dAP.dQ pair were diagnostic for the presence of 11 base pairs. The resonance for the dAP-dQ base pair was assigned on the basis of a combination of 1D NOE measurements, temperature-dependent line width, and chemical shift measurements. We conclude that dP and dQ are competent base-pairing partners for dAP in duplex DNA and are reasonable condidates for use in the design of novel base-pairing nucleoside analogs.

  Stereocontrolled syntheses of C-linked deoxyribosides of 2-hydroxypyridine and 2-hydroxyquinoline

  摘要：

  2'-Deoxy-C-ribosides 4 and 5 were prepared in optically active form by a route expected to be generally useful for the synthesis of the alpha- or beta-anomers of 2'-deoxy-C-ribosides. Key steps are the addition of an organometallic reagent to aldehyde 7, mesylation of the resulting alcohol, and stereospecific deprotection/cyclization to yield the 2'-deoxy-C-riboside (7 + 8 --> 9/10; 9 --> 11).

• Synthesis of 6-Substituted 2(1H)-Pyridon-3-yl C-2′-Deoxyribonucleosides
  作者：Hubert Chapuis、Tomáš Kubelka、Nicolas Joubert、Radek Pohl、Michal Hocek

  DOI：10.1002/ejoc.201101662

  日期：2012.3

  Two approaches to the synthesis of the title 6-substituted 2(1H)-pyridon-3-yl C-2′-deoxyribonucleosides have been pursued. A protected 6-aminopyridine C-nucleoside intermediate was converted into the N-oxide followed by Ac2O-mediated rearrangement and final deprotection to give 6-acetylamino-2-oxo(1H)-pyridin-3-yl deoxyribonucleoside. Due to the unusually high stability of the N-acetyl group, the full

  已探索了两种合成标题 6-取代的 2(1H)-pyridon-3-yl C-2'-脱氧核糖核苷的方法。受保护的 6-氨基吡啶 C-核苷中间体被转化为 N-氧化物，然后是 Ac2O 介导的重排和最终脱保护，得到 6-乙酰氨基-2-氧代 (1H)-吡啶-3-基脱氧核糖核苷。由于 N-乙酰基异常高的稳定性，完全脱保护没有成功。在第二种方法中，6-氯-2-吡啶酮被转化为二酰胺磷酸酯，其经历邻位镁化和碘化得到3-碘衍生物。然后将其与糖醛进行 Heck 偶联，所得产物脱保护得到 6-氯-2-氧代 (1H)-吡啶-3-基脱氧核糖核苷，其直接或再保护后转化为 6-甲基- , 6-氨基-, 和 6-未取代的吡啶酮 C-核苷。最终的核苷非常不稳定，容易差向异构化和/或氧化，这限制了（但不排除）它们在化学生物学中的进一步应用。

• Synthesis of 3-(2-deoxy-β-d-ribofuranosyl)pyridin-2-one and 2-amino-6-(N,N-dimethylamino)-9-(2-deoxy-β-d-ribofuranosyl)purine derivatives for an unnatural base pair

  An unnatural base pair, 2-amino-6-(N,N-dimethylamino)purine (denoted x) and pyridin-2-one (denoted y), was designed to prove the structural requirements for base pair formation involving shape complementarity. It was expected that y might satisfy the structural requirements for pairing with x, in which the bulky 6-dimethylamino group may eliminate base pairing with the natural bases. As chemical or biological substrates for DNA synthesis, the phosphoramidite of x and the 2'-deoxy-C3-ribonucleoside triphosphate of y (dyTP) were synthesized, and the incorporation experiment was demonstrated by using the Klenow fragment of Escherichia call DNA polymerase I.
