  摘要：

  7-Substituted 8-aza-7-deazaadenosines la-e were synthesized by Sonogashira cross coupling from the corresponding 7-iodo nucleoside in 36- 79% yields. Starting from 7-bromo (or 7-iodo)-8-aza- 7-deazaadenine, 2a,b were obtained by acid-catalyzed glycosylation followed by deprotection in 53 and 35% yields, respectively. Compounds 2b was applied to cross coupling reaction to give 2c-d in 34-95% yield. Compounds 2a and 4b were further transformed to the phosphoramidites 5 and 6b in 9 and 49% overall yields, which were incorporated into oligonucleotides.

  mechanism of recognition by the wild‐type (WT) E. coli purine nucleoside phosphorylase (PNP) versus its Ser90Ala mutant. The results were analyzed from viewpoint of the role of the Ser90 residue and the structural features of the bases. It was found that the Ser90 residue of the PNP 1) plays an important role in the binding and activation of 8‐aza‐7‐deazapurines in the synthesis of their nucleosides, 2) participates

The pK(a) values indicate that the 7-non-functionalized nucleosides 1a (pK(a) 5.8) and 15 (pK(a) 6.4) are possibly protonated in neutral conditions when incorporated into RNA. The nucleosides 3a-d exist predominantly in the keto (lactam) form with K(TAUT) (keto/enol) values of 400-1200 compared to 10(3)-10(4) for pyrrolo[2,3-d]pyrimidine isoguanosine derivatives 4a-c

  This paper describes the synthesis of a novel 8-aza-7-deazapurin-2,6-diamine (DPP)-containing peptide nucleic acid (PNA) monomer and Boc protecting group-based oligomerization of PNA, replacing adenine (A) with DPP monomers in the PNA strand. The PNA oligomers were synthesized against the biologically relevant SV40 promoter region (2494-AATTTTTTTTATTTA-2508) of pEGFP-N3 plasmid. The DPP-PNA.DNA duplex

  本文介绍了新型的含8-氮杂7-脱氮嘌呤-2,6-二胺（DPP）的肽核酸（PNA）单体的合成以及基于Boc保护基的PNA的低聚反应，用DPP取代了腺嘌呤（A） PNA链中的单体。针对pEGFP-N3质粒的生物学相关SV40启动子区域（2494-AATTTTTTTTATTATTTA-2508），合成了PNA寡聚物。与正常双链体（A-PNA.DNA）相比，DPP-PNA.DNA双链体显示出增强的稳定性。DPP单体的电子分布表明，DPP具有比2,6-二氨基嘌呤更好的电子给体性能。紫外熔融和热力学分析表明，与A-PNA.DNA相比，含有二氨基吡唑并（3,4-d）嘧啶部分（DPP）的PNA低聚物稳定了PNA.DNA杂种。DPP-PNA.DNA双链体显示出更高的水活度（Deltanw = 38。5）与A-PNA.DNA双链体相比（Deltanw = 14.5）。含有DPP或未修饰核碱基-A的PNA.DNA双链体的50

  Several pyrazolo[3,4-d]pyrimidine analogues of the potent antitumor agent N-4-12-(2-amino-4(3H)-oxo-7H-pyrrolo [2,3-d]pyrimidin-5-yl)ethyl]benzoyl}-L-glutamic acid (LY231514, 5) have been prepared. A principal synthetic step proved to be a palladium-catalyzed C-C coupling of the 5-halo-substituted pyrazolo[3,4-d]pyrimidines 12-15 with dimethyl 4-ethynylbenzoyl-L-glutamate (16). An additional pyrazolo[3,4-d]pyrimidine analogue of 5 possessing an isofolic acid bridge unit (-NHCH2-) was prepared by reductive alkylation of diethyl 4-formylbenzoyl-L-glutamate (31) with 2-methyl-5-amino-4(3H)-oxo-7H-pyrazolo[3,4-d]pyrimidine (30). Only compound 26 proved to have in vitro cell growth inhibitory activity.
