  • Enantiospecific Synthesis of Pseudoacarviosin as a Potential Antidiabetic Agent
    作者:Tony K. M. Shing、Hau M. Cheng、Wai F. Wong、Connie S. K. Kwong、Jianmei Li、Clara B. S. Lau、Po Sing Leung、Christopher H. K. Cheng

    A pseudo-1,4'- N-linked disaccharide, pseudoacarviosin 5, was constructed via a key palladium-catalyzed coupling reaction of pseudoglycosyl chloride 8 (prepared from d-glucose via a novel direct intramolecular aldol addition in 12 steps) and pseudo-4-amino-4,6-dideoxy-alpha- d-glucose 9 (prepared from l-arabinose via an unusual trans-fused isoxazolidine-selective intramolecular nitrone-alkene cycloaddition
    伪1,4'-N-连接的二糖伪拟紫薇香素5是通过钯在关键的钯催化的拟糖基氯8的偶联反应(由d-葡萄糖通过12步新颖的直接分子内羟醛加成反应制得的)和拟糖基氯构成的。 4-氨基-4,6-二脱氧-α-d-葡萄糖9(由A-阿拉伯糖通过不寻常的反式融合的异恶唑烷选择性分子内氮烯-烯烃环加成反应制备而成,共11步)。伪胡萝卜素5已被证明是α-葡糖苷酶的有效抑制剂,尤其是与血糖控制有关的肠粘膜酶蔗糖酶和葡糖淀粉酶。
  • The Structure and Stereochemistry of Gabosine K: Syntheses of 7-O-Acetylstreptol and 7-O-Acetyl-1-epi-streptol
    作者:Tony Shing、Hau Cheng
    DOI:10.1055/s-0029-1218540
    日期:2010.1
    Gabosine K, whose structure was erroneously assigned previously as 7-O-acetyl-4-epi-streptol, has been synthesized for the first time from d-glucose via a key carbocyclization strategy, intramolecular direct aldol reaction of a 2,6-diketone, in 15 steps with 13.5% overall yield. In the same manner, (+)-7-O-acetyl-streptol has been constructed for NMR spectral comparison. The structure, relative and absolute configurations of (-)-gabosine K are now revised and established as (-)-7-O-acetyl-1-epi-streptol, that is, (1R,2S,3S,4R)-tetrahydroxy-5-acetoxymethylcyclohex-5-ene. Since the specific rotation of the natural product is not available, the absolute configuration of natural gabosine K is either (-)-7-O-acetyl-1-epi-streptol or its enantiomer.
    Gabosine K 的结构以前被错误地归类为 7-O-acetyl-4-epi-streptol ,该化合物是通过一种关键的碳环化策略--2,6-二酮的分子内直接醛醇反应--首次从 d-葡萄糖中合成的,共经过 15 个步骤,总收率为 13.5%。以同样的方式,还构建了 (+)-7-O- 乙酰基链烷醇,用于核磁共振光谱比较。(-)-gabosine K 的结构、相对构型和绝对构型现已修订并确定为 (-)-7-O-乙酰基-1-epi-链醇,即 (1R,2S,3S,4R)-四羟基-5-乙酰氧甲基环己-5-烯。由于无法获得天然产物的特定旋转,因此天然棉子碱 K 的绝对构型是 (-)-7-O- 乙酰基-1-epi-链醇或其对映体。
  • Inhibition of Glutathione <i>S</i>-Transferase M1 by New Gabosine Analogues Is Essential for Overcoming Cisplatin Resistance in Lung Cancer Cells

    A new class of human GST inhibitors has been identified via rational design approach; we report their discovery, synthesis, inhibitory activity, and synergetic effect in combination with cisplatin against A549 lung cancer cell line. The results of this effort show that the lead 4-O-decyl-gabosine D (24) has optimum synergetic effect in A549 human lung adenocarcinoma epithelial cell and that this activity involves inhibition of glutathione S-transferase M1, apparently consistent with siRNA-mediated knockdown of GSTM1 gene.
  • Synthesis of chiral hydroxylated enones as potential anti-tumor agents
    作者:Tony K.M. Shing、Ho T. Wu、H.F. Kwok、Clara B.S. Lau
    DOI:10.1016/j.bmcl.2012.10.026
    日期:2012.12
    A series of chiral hydroxylated enones were synthesized as COTC ether analogues to investigate the structural features required for optimal and selective anti-tumor activity. The cytotoxicity of the seven COTC ether analogues against WRL-68 normal and HepG2, HL-60 cancer cell lines were measured. C-4 ether analogues with an aliphatic chain substituent were found to be more favorable than their aromatic counterparts. Inversion of the configuration at C-4 in 5e to give 5f only resulted in reduced selectivity towards cancer cells. These results show that 4-O-pentyl-gabosine D (5e) has optimum selectivity and cytotoxicity towards two cancer cell lines. (c) 2012 Elsevier Ltd. All rights reserved.

Five bicyclo[4.1.0]heptyl-based carbaglucoses were tested with this enzyme, and our results are consistent with pseudoglycosidic bond cleavage that occurs via SN1 transition states that include nonproductive
    糖苷水解酶 (GH) 催化糖缀合物的水解,其中酶在催化循环期间编排一系列构象变化。因此,一些 GH 家族,包括 α-淀粉酶 (GH13),在动力学上隐藏了它们的化学步骤。为了解决 GH13 酶的这个问题,我们制备了七种基于环己烯基的 α-d-吡喃葡萄糖苷卡巴糖,我们证明它们是 GH13 酵母 α-葡萄糖苷酶的良好共价抑制剂。离去基团的速率常数和 pKa 之间的线性自由能关系向上弯曲,这表明机制发生了变化,较好的离去基团通过 SN1 机制反应,而较差的离去基团的反应速率受在与酶促亲核试剂进行快速 SN2 反应之前,Michaelis 复合物的构象变化。用这种酶测试了五种基于双环 [4.1.0] 庚基的卡巴葡萄糖,我们的结果与通过 SN1 过渡态发生的假糖苷键切割一致,包括离去基团与酶的非生产性结合。总之,我们表明,这两种卡巴糖的构象正交反应揭示了酶和天然底物的米氏复合物所经历的构象变化所隐藏
