  氨基酰胺和3'- N-氨基磺酸修饰的DNA的合成及核酸结合特性

  摘要：

  已开发出一种新的合成路线，用于制备磺酰胺和3'- N-氨基磺酸酯修饰的二核苷。的合成利用4-硝基苯基氯磺酸以制备4-硝基苯基3'-或5'-氨基磺酸酯（例如，18和27），其联接平稳地与其他核苷的醇或胺官能团。使用NMR和CD光谱比较了磺酰胺和3'- N-氨基磺酸酯修饰的二核苷d（TnsnT）和d（TnsoT）的构象性质与天然二核苷酸d（TpT）。虽然两种修饰导致从C2'- 5'-末端核糖环的构象平衡的移位内切到一个优选的C3'-内切构象，只有3'- N-氨基磺酸酯修饰的二聚体显示出采用碱基堆积的螺旋构象的倾向增加。将磺酰胺和3'- N-氨基磺酸酯修饰掺入DNA序列d（GCGT 10 GCG）中，可以使用UV热变性实验确定双链体的解链温度。这表明，磺酰胺修饰显着破坏了互补DNA和RNA的双链体的稳定性。然而，3'- N-氨基磺酸盐修饰对双链体稳定性几乎没有影响，甚至在低盐浓度下也能稳定DNA双链体。这些结果表明3'-

  Crystal Structure and Photochemical Behavior in Solution of the 3‘-N-Sulfamate Analogue of Thymidylyl(3‘-5‘)thymidine

  摘要：

  [GRAPHICS]The 3'-N-sulfamate analogue of thymidylyl(3'-5')thymidine (TnsoT, 1) exhibits a preference for a C3'-endo conformation in the solution and solid states. Its photochemical behavior in solution is compared to that of its natural counterpart, thymidylyl(3'-5')thymidine (TpT, 2), to get further insight into the significance of the C3'-endo conformation on the photoproduct formation at the single-stranded dinucleotide level. Irradiation at 254 nm of 1 led to the same type of photoproducts as observed with 2. However, 1 was significantly more photoreactive than 2, and accordingly, the initial rate of photoproduct formation was enhanced in accordance with its propensity to base stack compared to 2. The corresponding quantum yields were determined and showed that the enhancement factor (1 compared to 2) is moderate for the cyclobutane pyrimidine dimer (CPD) (1.26) and much higher for the (6-4) photoproduct (1.8). These data strongly suggest that the CPD and (6-4) photoproduct arise from distinct minor stacked conformations.

  A novel synthetic route for the preparation of sulfamide- and 3′-N-sulfamate-modified dinucleosides has been developed. The synthesis utilises 4-nitrophenyl chlorosulfate to prepare 4-nitrophenyl 3′- or 5′-sulfamates (e.g., 18 and 27), which couple smoothly with the alcohol or amine functionalities of other nucleosides. The conformational properties of the sulfamide- and 3′-N-sulfamate-modified dinucleosides

  Replacing phosphodiester linkages in DNA with neutral 3′-N-sulfamate groups has little effect on the binding affinity for complementary DNA or RNA, whereas incorporation of sulfamide groups into DNA results in considerable destabilisation of isosequential duplexes.
