  • Probing Synergy between Two Catalytic Strategies in the Glycoside Hydrolase <i>O</i>-GlcNAcase Using Multiple Linear Free Energy Relationships
    作者:Ian R. Greig、Matthew S. Macauley、Ian H. Williams、David J. Vocadlo
    DOI:10.1021/ja904506u
    日期:2009.9.23
    revealing changes in mechanism, transition state, and rate-determining step upon concomitant variation of both nucleophilic strength and leaving group abilities are observed. The observed changes in mechanism reflect the roles played by the enzymic general acid and the catalytic nucleophile. Significantly, these results illustrate how the enzyme synergistically harnesses both modes of catalysis; a feature that
    人类 O-GlcNAcase 在调节丝氨酸和苏酸残基与 β-O 连接的 N-乙酰氨基葡萄糖单糖单元 (O-GlcNAc) 的翻译后修饰方面发挥着重要作用。O-GlcNAcase 的机制涉及底物的 2-乙酰基基团的亲核参与以取代糖苷连接的离去基团。这种酶对底物结构变化的耐受性使我们能够使用几个系列的底物来表征 O-GlcNAcase 过渡态,以产生多个同时的自由能关系。观察到伴随亲核强度和离去基团能力变化的机制、过渡态和速率决定步骤的变化模式。观察到的机制变化反映了酶通酸和催化亲核试剂所起的作用。重要的是,这些结果说明了酶如何协同利用两种催化模式;许多小分子催化模型都没有的特征。这些研究还表明了氧代碳鎓离子中间体在 O-GlcNAcase 催化的氨基葡萄糖解中的动力学意义,探索了使用酶过渡态结构的非原子研究可能学到的知识的局限性,并提供了关于保留超家族的一般见解糖苷解酶作为有效的催化剂。
  • Iminosugar glycoconjugates
    申请人:Technische Universität Graz
    公开号:EP1903034A1
    公开(公告)日:2008-03-26
    The iminosugar conjugates according to the invention are N-alkylated 1,5-dideoxy-1,5-iminohexitol or 1,5-dideoxy-1,5-iminopentitol derivatives. The iminosugar component can be, for example, D-gluco-, L-ido-, D-galacto-, D-manno-, 2-acetamido-2-deoxy-D-gluco- or xylo-configuration. The N-substituent is a protected L-α-aminoacid derivative, showing L-lysine-like structural features. The linkage between the carbohydrate and the peptide component is not via the usual glycosidic position, but shows structural features of a very stable tertiary amine. Thus the linkage is very stable. These new compounds are synthesised by using catalytic intramolecular reductive amination of dicarbonyl sugars with partially protected amino acids. The process of intramolecular reductive amination itself is carried out using Pearlman's catalyst (Pd(OH)2/C) and H2 at ambient pressure and room temperature. The resulting accessible class of iminosugar conjugate compounds is represented by the general structure shown in Figure 4(c). The alkyl chain length parameter n can be freely chosen from n=0 upwards. Preferably n is between 0 and 10, and more preferably n is 2, 3, or 4. Residue R1 can be chosen from H, OH, or NHAc, with Ac being Acetyl. R2 can be H, OH, or NHAc. R3, R4, R5, R6 can be H or OH. R7 and R8 can be H, CH2OH CH3, COQH, or COOR with R being Alkyl or Aryl. R9 and R10 can be chosen from H, NH2, NHR, with R being a protective group, an amino acid, a peptide, or a protein. R11 can be OH, O-Alkyl, O-Aryl, NH2, N-Alkyl, N-Aryl, amino acid or peptide, connected via an amide bond.
    本发明涉及的亚基糖缀合物是N-烷基化的1,5-二脱氧-1,5-亚基己糖醇或1,5-二脱氧-1,5-亚基戊糖醇衍生物。亚基糖部分可以是例如D-葡萄糖L-艾杜糖D-半乳糖D-甘露糖、2-乙酰基-2-脱氧-D-葡萄糖木糖构型。N-取代基是一种保护的L-α-氨基酸生物,显示出类似L-赖氨酸的结构特征。糖和肽组分之间的连接不是通过常规的糖苷位置,而是显示出非常稳定的叔胺的结构特征。因此,这种连接非常稳定。这些新化合物是通过使用催化剂催化二羰基糖与部分保护的氨基酸之间的分子内还原胺化合成的。分子内还原胺化过程本身是在常压和室温下使用Pearlman催化剂(Pd(OH)2/C)和氢气进行的。由此得到的一类亚基糖缀合物化合物的可及性由图4(c)所示的通用结构表示。烷基链长参数n可以从n=0开始自由选择。优选n在0到10之间,更优选n为2、3或4。残基R1可以从H、OH或NHAc中选择,其中Ac代表乙酰基。R2可以是H、OH或NHAc。R3、R4、R5、R6可以是H或OH。R7和R8可以是H、CH2OH、CH3、COQH或COOR,其中R是烷基或芳基。R9和R10可以从H、NH2、NHR中选择,其中R是一个保护基团、氨基酸、肽或蛋白质。R11可以是OH、O-烷基、O-芳基、NH2、N-烷基、N-芳基、氨基酸或肽,通过酰胺键连接。

    PUGNAc and NAG-thiazoline, provide insight into the features of NAG-thiazoline that resemble the transition state and reveal where PUGNAc fails to capture significant binding energy. These studies also point to late transition state poise for the O-GlcNAcase catalyzed reaction with significant nucleophilic participation and little involvement of the leaving group. The potency of NAG-thiazoline, its transition

    Anhydrous FeCl3 in CH2Cl2 has been found to readily anomerize β-glycopyranosides to their corresponding α-anomers in good yields and selectivities at room temperatures. Acetyl- and benzoyl-protected oxygen sugars yielded the best results.

    adenocarcinoma TA3, leukemia L1210, or leukemia P-288 cells at 1-0.01 mM concentration in vitro. Some of these derivatives were less active after O-deacetylation. Analogs of 1 in which NH2-1 was replaced by OH- or OAc-1 were also active on the same cell systems. The growth-inhibitory activity was correlated with inhibition of the incorporation of 2-amino-deoxy-D-glucose and L-leucine into a macromolecular fraction
