  Synthesis of Triazole-Linked Oligonucleotides with High Affinity to DNA Complements and an Analysis of Their Compatibility with Biosystems

  摘要：

  New oligonucleotide analogues with triazole internucleotide linkages were synthesized, and their hybridization properties were studied. The analogues demonstrated DNA binding affinities similar to those of unmodified oligonucleotides. The modification was shown to protect the oligonucleotides from nuclease hydrolysis. The modified oligonucleotides were tested as PCR primers. Modifications remote from the 3'-terminus were tolerated by polymerases. Our results suggest that these new oligonucleotide analogues are among the most promising triazole DNA mimics characterized to date.

  An Alternative Route to the Preparation of (3′ → 5′) Methylene Acetal Linked Di- and Trinucleosides

  摘要：

  脱氧核苷3′-O-(甲硫基甲基)乙缩醛1与碘代琥珀酰亚胺(NIS)和二丁基磷酸酯反应，生成相应的3′-O-(二丁氧基磷酰氧)甲基乙缩醛6。后者与适当保护的脱氧核苷受体3在三甲基硅基三氟甲磺酸盐(TMSOTf)的存在下缩合，通常得到(3′ → 5′)亚甲基乙缩醛连接的二聚体d(B1 ∧ B2) 4。此外，TMSOTf促进的供体6 (B1 = CBz)与3′-O-(甲硫基甲基)胸苷(8)的偶联反应生成二聚体9。9与NIS和二丁基磷酸酯反应生成二聚体10，成功用于与受体3(B2 = CBz和ABz)的TMSOTf辅助融合，得到相应的三聚体d(C∧T∧C) 11和d(C∧T∧A) 12。

  appropriately protected thymidine, d-cytidine or d-guanosine acceptors 5a–c, using trimethylsilyl trifluoromethanesulfonate (TMSOTf) as the activating system, furnished the respective (3′→5′) methylene acetal linked dimers d(T∧T), d(T∧G). Similarly, TMSOtf-promoted condensation of (5′-O,4-N)dibenzoyl-3′-O-acetyloxymethyl-2′-deoxycytidine with acceptors 5a–c yielded the corresponding d(C∧T), d(C∧C)

  使用三甲基甲硅烷基三氟甲磺酸酯（5a-c）将5'-O-乙酰丙酰基-3'-O-苯甲酰氧基甲基胸苷或5'-O-苯甲酰基-3'-O-乙酰氧基甲基胸苷与适当保护的胸苷，d-胞苷或d-鸟苷受体5a–c缩合（ TMSOTf）作为活化系统，提供了各自的（3'→5'）亚甲基缩醛连接的二聚体d（T∧T），d（T∧G）。同样，TMSOtf促进的（5'-O，4-N）二苯甲酰基-3'-O-乙酰氧基甲基-2'-脱氧胞苷与受体5a–c的缩合产生相应的d（C∧T），d（C∧C ）和d（C∧G）二聚体。

  Treatment of 5'-O-benzoylthymidine 1 with a mixture of acetic anhydride. acetic acid and dimethyl sulfoxide yielded 5'-O-benzoyl-3'-O-methylthiomethylthymidine 2, which was converted via the 3'-O-bromomethyl derivative into 3'-O-(omega-aminoalkoxymethyl)thymidines 7 bearing a 6, 8 or 10 methylene groups long hydrocarbon chain, and finally to their 5'-triphosphates 10. The latter compounds were shown to be terminators of DNA synthesis catalysed by thermostable Tet/z DNA-polymerase, and may be labelled at the aliphatic amino group with fluorescent probes.

  A series of 15-mer oligodeoxynucleotide analogues were synthesized, and their thrombin inhibitory activities in vitro and in vivo were evaluated. These oligodeoxynucleotide analogues share the same sequence (GGTTGGTGTGGTTGG) but have one or more phosphodiester linkages replaced by a neutral formacetal group. The results obtained from monosubstitutions show that no single phosphodiester group is critical for the thrombin inhibitory activity, suggesting that the interaction between the oligodeoxynucleotide and thrombin is based on a multiple-site charge-charge interaction. Analysis of the effects of different phosphodiester replacements indicates that the backside and left side of the chairlike structure formed by the molecule may be involved in binding with thrombin, presumably by having direct contacts with the anion-binding exosite of the enzyme. For the oligodeoxynucleotides containing two noncontiguous formacetal groups, the effect of the disubstitution is the sum of the effects obtained from the corresponding two monosubstitutions. Infusion of an oligodeoxynucleotide containing four formacetal groups into monkeys showed an increased in vivo anticoagulant effect and an extended in vivo half-life compared to the unmodified oligodeoxynucleotide.

  A new and promising sequencing technology called sequencing-by-synthesis (SBS) enables fast determination of DNA sequences. 2'-Deoxynucleotides containing the (2-cyanoethoxy)methyl (CEM) group at the 3'-O-position are potential reversible terminators for the SBS technology. Herein we describe the synthesis, the incorporation by several polymerases, and the cleavage of this 3'-O-blocking group using 3'-O-CEM-thymidinyl-5'-O-triphosphale 7 as an example.
