    Synthesis of a Novel UDP-carbasugar as UDP-galactopyranose Mutase Inhibitor
    摘要:
    The multistep synthesis of a novel UDP-C-cyclohexene, designed as a high energy intermediate analogue of the UDP-galactopyranose mutase (UGM) catalyzed isomerization reaction, is reported. The synthesis of the central carbasugar involved the preparation of a galactitol derivative bearing two olefins necessary for the construction of the cyclohexene ring by a ring-closing metathesis as a key step. Further successive phosphonylation, deprotection, and UMP coupling provided the target molecule. The final molecule was assayed against UGM and compared with UDP-C-Galf, the C-glycosidic UGM substrate analogue.

  • Synthesis and Inhibition Properties of Conformational Probes for the Mutase-Catalyzed UDP-Galactopyranose/Furanose Interconversion

    with conformationally restricted analogues of its substrate. Thus, we describe the straightforward synthesis of two C-glycosidic UDP-galactose derivatives: analogue 1, presenting a galactose moiety locked in a bicyclic (1,4)B boat conformation, and UDP-C-Galf 2, where the galactose residue is locked in the conformation of the mutase substrate. The two molecules were found to be inhibitors of UDP-galactose
    UDP-半乳糖突变酶是一种黄素酶,可催化UDP-半乳糖吡喃糖异构化为UDP-半乳糖呋喃糖,这是重要细菌寡糖生物合成的关键步骤。已经提出了用于这种独特的环收缩的几种机理,其中一种涉及推定的1,4-脱水半乳糖吡喃糖作为反应中的中间体。这项研究的目的是用其底物的构象受限的类似物探测突变酶结合位点。因此,我们描述了两种C-糖苷UDP-半乳糖衍生物的直接合成:类似物1,呈现锁定在双环(1,4)B船构象中的半乳糖部分,以及UDP-C-Galf 2,其中半乳糖残基为锁定在突变酶底物的构象中。发现这两个分子是UDP-半乳糖变酶的抑制剂,其水平取决于该酶的氧化还原状态。用UDP-C-Galf 2可以观察到对天然酶的强抑制作用,但对还原酶的抑制作用很小,而1在天然和还原条件下均表现出中等抑制水平。这些数据提供了还原酶和天然酶中突变酶结合口袋的显着构象差异的证据,即酶从低Galf亲和力状态(还原酶)转变为非常强

  • Photoinduced electron transfer and chemical α-deoxygenation of d-galactono-1,4-lactone. Synthesis of 2-deoxy-d-lyxo-hexofuranosides

    Two simple procedures for the synthesis of 2-deoxy-D-lyxo-hexono-1,4-lactone are described. Reductive cleavage of a 2-O-tosyl derivative of D-galactono-1,4-lactone in the presence of sodium iodide afforded the 2-deoxy derivative. On the other hand, alpha-deoxygenation of D-galactono-1,4-lactone was easily achieved by photochemical electron transfer deoxygenation of HO-2 as the 3-(trifluoromethyl)benzoate
    描述了两个简单的合成2-脱氧-D-lyxo-六邻--1,4-内酯的程序。在碘化钠的存在下,D-半乳糖-1,4-内酯的2-O-甲苯磺酰基衍生物的还原裂解得到2-脱氧衍生物。另一方面,通过将HO-2作为3-(三氟甲基)苯甲酸酯进行光化学电子转移脱氧,可以容易地实现D-半乳糖-1,4-内酯的α-脱氧。合成了甲基2-脱氧-β-D-lyxo-六呋喃糖苷(“甲基2-脱氧-β-D-半乳糖呋喃糖苷”),并测试了其作为来自腐霉青霉的exoβ-D-半乳糖苷酶的底物。在反应之后进行HPAEC,显示2-脱氧-β-D-D-半乳糖呋喃糖苷甲基未通过与酶温育而水解。2-脱氧内酯 2-脱氧-β-D-半乳糖呋喃糖苷也不能充当与4-硝基苯基β-D-半乳糖醛糖苷反应的抑制剂。目前和我们以前的结果表明,半乳糖呋喃糖苷的C-2,C-3和C-6处的羟基对于与外切β-D-半乳糖醛酸苷酶的相互作用至关重要。
