    On the regioselectivity of the protease subtilisin towards the acylation of enantiomeric pairs of benzyl and naphthyl glycopyranosides. Part 2
    摘要:
    Subtilisin-catalyzed esterification of several enantiomeric benzyl and naphthyl glycopyranosides has been investigated. The D-sugar derivatives were all good substrates and subtilisin regioselectivity was similar with all the compounds tested, the 3-OH being acylated predominantly. On the other hand, most of the L-glycopyranosides were transformed during longer reaction times with a lower regioselectivity, the 2-OH being preferentially but not exclusively acylated.

    lariat ethers have been synthesized. These macrocycles and their derivatives proved to be efficient catalysts in the cyclopropanation of (E)-3-phenyl-2-(phenylsulfonyl)acrylonitrile performed with diethyl bromomalonate under mild phase transfer conditions. Among the catalysts tested, the macrocycle having methyl α-d-galactopyranoside unit generated the highest asymmetric induction (80% ee). In the

    Glycosides of 3-hydroxy-4-pyridinones were synthesized and characterized by mass spectrometry, elemental analysis, 1H and 13C NMR spectroscopy, and in one case by X-ray crystallography. The Cu2+ complex of a novel 3-hydroxy-4-pyridinone was synthesized and characterized by IR and X-ray crystallography, showing the ability of these compounds to chelate potentially toxic metal ions. An MTT cytotoxicity assay of a selected glycosylated compound showed a relatively low toxicity of IC50 = 570 ± 90 μM in a human breast cancer cell line. The pyridinone glycosides could be cleaved by a broad specificity beta-glycosidase, Agrobacterium sp.β-glucosidase, and for one compound kcat and Km were determined to be 19.8 s−1 and 1.52 mM, respectively. Trolox Equivalent Antioxidant Capacity (TEAC) values were determined for the free pyridinones, indicating the good antioxidant properties of these compounds. Metal-Aβ1-40 aggregates with zinc and copper were resolubilized by the non-glycosylated pyridinone ligands.
    3-羟基-4-吡啶酮的糖苷被合成并通过质谱、元素分析、1H和13C核磁共振波谱进行表征,其中一例通过X射线晶体学进行表征。合成并表征了一种新型3-羟基-4-吡啶酮的Cu2+配合物,通过IR和X射线晶体学表明这些化合物具有潜在的螯合有毒金属离子的能力。对选定的糖基化化合物进行的MTT细胞毒性测定显示,在人乳腺癌细胞系中具有相对较低的毒性,IC50 = 570 ± 90 μM。吡啶酮糖苷可以通过广特异性β-糖苷酶,即根癌农杆菌β-葡糖苷酶分解,对于一种化合物,kcat和Km分别为19.8 s−1和1.52 mM。测定了自由吡啶酮的Trolox等效抗氧化能力(TEAC)值,表明这些化合物具有良好的抗氧化性能。非糖基化的吡啶酮配体可以解溶锌和铜的金属-Aβ1-40聚集体。

    Enzymatic glucosylation of unnatural products by natural glycosyltransferases (GTs) has great potential in creating novel and bioactive glucosides. A new GT (AaGT3) from Aloe arborescens exhibited catalytic promiscuity and high efficiency to diverse unnatural naphthols. By combing the substrate flexibility and catalytic reversibility of AaGT3, a cost-effective enzymatic approach to novel and bioactive

    Enzymatic catalysis in mild conditions plays a pivotal role in green chemistry, and the mining and the directed evolution of novel enzymes are crucial for the utilization of efficient biocatalysts. Glycosyltransferases (GTs) hold great promise in the synthesis of many valuable glycosylated products; however the narrow substrate scope and low catalytic efficiency of GTs often limit their broader applications
    温和条件下的酶催化在绿色化学中发挥着关键作用,新型酶的挖掘和定向进化对于高效生物催化剂的利用至关重要。糖基转移酶 (GT) 在许多有价值的糖基化产品的合成中具有广阔的前景;然而GTs的底物范围窄和催化效率低往往限制了其更广泛的应用。GT 的系统发育挖掘和定向进化是生成强大酶的成熟方法。这些已建立的方法的组合被称为 PhyloDirect,通过定向进化将性能优异的酶的鉴定与其工程结合起来,以快速满足生物催化的需求。在此处,我们报告并验证了一种基于系统发育的组合定向进化 (PhyloDirect) 方法,以提高新型 GT BarGT-3 的性能。建立了基于UDP-葡萄糖回收的单GT高通量筛选系统。通过一轮定向进化,获得了一种有前途的变体 I63P/H108G,其催化效率显着提高(对乙酰氨基酚为 28 倍),并增加了对多种具有合成价值的底物(酚、香豆素和类黄酮,高达 5)的转化。 -折叠)。这种
