    Triazole carboxylic acids as anionic sugar mimics? Inhibition of glycogen phosphorylase by a d-glucotriazole carboxylate
    摘要:
    Triazole-carboxylic acids related to D-glucose and D-galactose may be prepared by intramolecular [1,3]-dipolar cycloadditions of azides to unsaturated esters, followed by bromine oxidation of the resulting triazoline. Such materials may provide a series of anionic mimics of carbohydrates. (C) 1997 Elsevier Science Ltd.

    用于突变酶催化的UDP-吡喃半乳糖/呋喃糖互变的构象探针的合成和抑制特性。
    摘要:
    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

    The C-disaccharide analogue of the sequence β-D-Galf-(1→3)-β-D-Glcp, an internal disaccharide of the capsular polysaccharide of Klebsiella K14 was synthesized by radical macrocyclization of temporarily tethered monosaccharides. The α-difluoro-C-analogue was obtained in three steps from D-galactono-1,4-lactone.

    日期:1999.8.1
    The chemical synthesis of two phosphono analogues of D-galactofuranosyl phosphate was performed. The natural phosphate seemed to be too labile to allow the chemical synthesis of UDP-Galf, these C-galactofuranosides are stable pharmacophores, and the cr-phosphono analogue has been easily converted into UDP-C-Galf. UDP-C-Galf was tested as a competitive inhibitor of UDP-galactopyranose mutase and showed inhibition of Galf formation. Thus, it is of potential interest as an antimycobacterial agent; as an active molecule against Trypanosoma cruzi, the causative agent of South American trypanosomiasis (Chagas' disease), and as a stable analogue for use in UDP-galactopyranose mutase crystallization studies.
