  N6-(3-碘苄基)腺苷-5'-N-甲基脲酰胺 (IB-MECA) 和相关 A3 腺苷受体配体的多药理学：过氧化物酶体增殖物激活受体 (PPAR) γ 部分激动剂和 PPARδ 拮抗剂活性表明其具有抗糖尿病潜力。

  摘要：

  检查 A3 腺苷受体 (AR) 配体（包括 A3 AR 激动剂、N6-(3-碘苄基)腺苷-5'-N-甲基脲酰胺 (1a, IB-MECA)）在人骨髓间充质干细胞 (hBM-MSC) 中的脂联素生成情况）。在该模型中，1a 显着增加了脂联素的产生，这与胰岛素敏感性的改善有关。然而，A3 AR 拮抗剂也促进 hBM-MSC 中脂联素的产生，表明 A3 AR 途径可能不直接参与脂联素促进活性。在一项靶标解卷积研究中，它们的脂联素促进活性与其与过氧化物酶体增殖物激活受体 (PPAR) γ 和 PPARδ 的结合活性显着相关。它们既充当 PPARγ 部分激动剂又充当 PPARδ 拮抗剂。在糖尿病小鼠模型中，1a 及其结构类似物 A3 AR 拮抗剂显着降低血清葡萄糖和甘油三酯水平，支持其抗糖尿病潜力。这些发现表明，这些化合物的多药效团可以为它们针对各种人类疾病的多效功效提供治疗见解。

  Stereoselective Synthesis of 2'-Deoxy-.beta.-D-threo-pentofuranosyl Nucleosides by the NBS-Promoted Coupling Reaction of Thioglycosides with Silylated Heterocyclic Bases

  摘要：

  The NBS-promoted coupling reaction of phenyl 3,5-O-isopropylidene-2-deoxy-1-thio-alpha-D-threo-pentofuranoside (5e) with silylated pyrimidine bases was found to proceed in a highly stereoselective manner (alpha:beta = 1:24-0:1) to afford 2'-deoxy-beta-D-threo-pentofuranosyl pyrimidine nucleosides in satisfactory yields. The highly stereoselective outcome is thought to result from an in situ anomerization-type mechanism, in which intimate ionic intermediates would be in equilibrium and anomerize to the sterically preferable a form. A subsequent S(N)2 type attack to the intermediate will lead to the beta-nucleosides. By using this method, the synthesis of L-nucleosides, 1-(2-deoxy-beta-L-threo-pentofuranosyl)thymine and cytosine derivatives, was also demonstrated by starting from the L-enantiomer of the thioglycoside. On the other hand, the reaction with purine bases was accompanied by the production of undesirable N-7 regioisomers besides the desired N-9 products. The product distribution of the regioisomers was, however, proved to change with reaction time. For instance, a long reaction period allowed the thermodynamically stable N-9 isomers to be exclusively produced with moderate selectivity (alpha:beta = 1:2-1:4.8). The isolated yields of the 9-beta isomers after purification were acceptable for practical use.

• Stereoselective synthesis of 4′-selenonucleosides using the Pummerer glycosylation reaction

  The syntheses of four selenonucleosides, namely 4 '-O-selenoadenosine, -cytidine, -thymidine, and -uridine are described. Commercially available D-ribonolactone was converted to the key intermediate 1,4-anhydro-4-seleno-D-ribitol in seven steps in overall excellent yield. Oxidation of the seleno-D-ribitol with MCPBA gave a single diastereomeric selenoxide in excellent yield, which upon Pummerer reaction in the presence of silylated purine or pyrimidine bases gave stereoselectively the corresponding 4'-beta-selenonucleosides. The stereochemistry at the anomeric center was determined by means of 1D-NOE experiments. (C) 2008 Elsevier Ltd. All rights reserved.

  A3 adenosine receptor (AR) ligands including A3 AR agonist, N6-(3-iodobenzyl)adenosine-5'-N-methyluronamide (1a, IB-MECA) were examined for adiponectin production in human bone marrow mesenchymal stem cells (hBM-MSCs). In this model, 1a significantly increased adiponectin production, which is associated with improved insulin sensitivity. However, A3 AR antagonists also promoted adiponectin production
