  1-β-d-呋喃核糖基苯并咪唑3'，5'-磷酸酯的衍生物模拟腺苷3'，5'-磷酸酯（cAMP）和鸟苷3'，5'-磷酸酯（cGMP）的作用

  摘要：

  根据MNDO方法预测的性质，设计了一系列1-β-D-呋喃呋喃糖基苯并咪唑3'，5'-磷酸酯（cBIMP）的新类似物，并由取代的苯并咪唑合成。通过MNDO方法计算每个苯并咪唑碱基的偶极子向量以及HOMO和LUMO能量，并确定cBIMP衍生物的亲脂性。通常，cBIMP衍生物激活cAMP依赖性蛋白激酶I和II，并优先结合位点B，特别是对于II型激酶，其中2-三氟甲基-cBIMP和5,6-二氟-cBIMP表现出最高的位点选择性。每个cBIMP衍生物都可以刺激cGMP刺激的环磷酸二酯酶（cGS-PDE），其中5,6-二甲基-cBIMP与cGMP一样有效，并且还可以抑制cGMP抑制的磷酸二酯酶（cGI-PDE）。仅2-三氟甲基-cBIMP和Rp-硫代磷酸酯（cBIMPS）（赤道P = S）对cPDE的水解具有抗性。如果有的话，将Sp-硫代磷酸酯缓慢水解。除了表现出高亲脂性外，用于诱导细胞凋亡和抑制增殖

  The present invention relates to a method for nucleic acid replication and novel artificial base pairs. The method of the present invention for nucleic acid replication is characterized in that a deoxyribonucleoside 5′-triphosphate, in which the hydroxyl group of phosphoric acid at the γ-position is substituted with a group selected from the group consisting of an amino group, a methylamino group, a dimethylamino group, a mercapto group and a fluoro group, is used as a substrate during replication reaction. The novel artificial base pairs of the present invention are characterized in that 7-(2-thienyl)-imidazo[4,5-b]pyridine (Ds) or an analog thereof forms a base pair with pyrrole-2-carbaldehyde (Pa) or an analog thereof.

  本发明涉及一种核酸复制方法和新型人工碱基对。本发明的核酸复制方法的特征在于，在复制反应过程中使用一种脱氧核苷酸5'-三磷酸作为底物，其中磷酸γ-位置的羟基被从以下群组中选择的一种群组所取代，所述群组包括氨基、甲基氨基、二甲基氨基、巯基和氟基。本发明的新型人工碱基对的特征在于，7-(2-噻吩基)-咪唑并[4,5-b]吡啶（Ds）或其类似物与吡咯-2-甲醛（Pa）或其类似物形成一对碱基。

  organic synthesis, biocatalysis using enzymes provides a more stereoselective and cost-effective approach. Synthesis of unnatural nucleosides by nucleoside base exchange reactions using nucleoside-metabolizing enzymes has previously shown that the 5-position recognition of pyrimidine bases on nucleoside substrates is loose and can be used to introduce functional molecules into pyrimidine nucleosides. Here

  在替代有机合成中，使用酶的生物催化提供了一种更具立体选择性和成本效益的方法。使用核苷代谢酶通过核苷碱基交换反应合成非天然核苷先前表明，核苷底物上嘧啶碱基的5位识别是松散的，可用于将功能分子引入嘧啶核苷中。在这里，我们探索了通过嘧啶核苷磷酸化酶（PyNP）的碱基交换反应将嘌呤假碱基掺入核苷中，证明咪唑五元环是该反应的必要结构。就苯并咪唑而言，碱基交换产生脱氧核糖形式，产率 96%，核糖形式，产率 23%。该反应还用 1 H-咪唑并[4,5-b]吩嗪（一种带有附加环的苯并咪唑类似物）进行，尽管核苷的产率仅为 31%。1 H和咪唑并[4,5-b]吩嗪核苷与 PyNP (PDB 1BRW) 活性位点之间的对接模拟H-咪唑并[4,5-b]吩嗪可以用作 PyNP 的底物。因此，使用PyNP的酶促取代反应可用于将许多嘌呤假碱基和具有各种官能团的苯并咪唑衍生物掺入核苷结构中，其具有作为诊断或治疗剂的潜在用途。
