  Large Stabilization of a DNA Duplex by the Deoxyadenosine Derivatives Tethering an Aromatic Hydrocarbon Group

  摘要：

  Novel deoxyadenosine derivatives tethering a phenyl or naphthyl group by means of an amido linker have been synthesized, and these derivatives, stacking on the 5' end of a DNA duplex, provide free energy contributions equal to or greater than that of the Watson-Crick A/T base pair.

  C5‘-Adenosinyl Radical Cyclization. A Stereochemical Investigation

  摘要：

  A variety of substituted 2'-deoxyadenosin-5'-yl radicals 3 were generated under different reaction conditions. Radicals 3 underwent intramolecular cyclization onto the C8-N7 double bond of the adenine moiety leading to aminyl radicals (5'S,8R)-4 and (5'R,8R)-4 and, eventually, to the corresponding cyclonucleosides 5 and 6. The effect of the solvent, the nature of the substituents, and the generation method of radicals 3 on the stereoselectivity of the C5'-radical cyclization have been considered. The observed increase of the (5'S)/(5'R) ratio by increasing the bulkiness of the R-1 group is explained in terms of steric repulsion between R-1 and the purine moiety which favors the C5'-endo conformation, whereas the effect of the water solvent in promoting the (5'R)-stereoselective cyclization is ascribed to intermolecular hydrogen bonding stabilizing the C5'-exo confomation.

• New thermolytic carbamoyl groups for the protection of nucleobases
  作者：Akihiro Ohkubo、Rintaro Kasuya、Kenichi Miyata、Hirosuke Tsunoda、Kohji Seio、Mitsuo Sekine

  DOI：10.1039/b816831h

  日期：——

  It was found that N-arylcarbamoyl and N-(phenylsulfonyl)carbamoyl (psc) groups could be effectively introduced onto the amino groups of deoxycytidine and deoxyadenosine derivatives and could be removed thermolytically. We succeeded in synthesizing DNA probes incorporating these thermo-removable protecting groups and developed a new system for molecular switching by changing the protection- and deprotection-modes using simple heating and re-carbamoylation with isocyanates. This reversible process enabled us to control the hybridization ability of the DNA probes.

  研究发现，N-芳基氨甲酰基和N-（苯磺酰基）氨甲酰基（psc）基团能够有效地引入到脱氧胞苷和脱氧腺苷衍生物的氨基上，并且能够通过热分解反应去除。我们成功合成了含有这些热可移除保护基团的DNA探针，并开发了一种新的分子开关系统，通过简单的加热和重新氨甲酰化与异氰酸酯的反应来改变保护和脱保护模式。这种可逆的过程使我们能够控制DNA探针的杂交能力。

  A solvent-free reaction employing a simple low-energy ball mill apparatus converts the amino groups of adenosine, 2-deoxyadenosine, cytidine, 2-deoxycytidine, guanosine, and 2-deoxyguanosine as well as some of their ribosyl O-protected derivatives to the corresponding bis-N-Boc carbamates. In the case of guanosine compounds, the carbonyl group of the base moiety was also blocked as its O-Boc enol carbonate

  2'-Deoxy, 3'-deoxy, and 2',3'-dideoxyribosyl surrogates of isoleucyl and methionyl sulfamate adenylates have been investigated to identify the pharmacophoric importance of the ribose group for the inhibition of Escherichia coli methionyl-tRNA (MRS) and isoleucyl-tRNA (IRS) synthetases. Molecular modeling of 2',3'-dideoxyribosyl Met-NHSO2-AMP (9) with the crystal structure of E. coli MRS revealed that
