  摘要：

  The stereoselective xylosylation of (RS)-1-phenylalkyl beta-D-glucosides was investigated using plant xylosyltransferase isolated from cultured Catharanthus roseus cells. Enzymatic xylosylation of (RS)-1-phenylethyl beta-D-glucoside afforded (R)-1-phenylethyl beta-primeveroside and (S)-1-phenylethyl beta-D-glucoside. The (R)-selective xylosylation of (RS)-1-phenylbutyl beta-D-glucoside also occurred to give (R)-1-phenylbutyl p-primeveroside and recovered (S)-1-phenylbutyl beta-D-glucoside. (C) 2010 Elsevier Ltd.

  摘要：

  几种生物活性的天然p-羟基苯丙基β-D-葡萄糖苷，如香草基β-D-葡萄糖苷、沙利度苷和异云杉醇苷，以及它们的糖苷类似物，通过简单的反应序列制备。通过利用乙酰化的葡萄糖溴化物以及芳香基团和温和的糖苷化促进剂，实现了高效的合成方法。去糖基物质p-O-乙酰化芳基丙基醇是通过还原相应的乙酰化醛或酸制备的。研究了各种立体选择性的1,2-trans-O-糖基化方法，包括DDQ-碘或ZnO-ZnCl2催化剂组合。其中，ZnO-碘已被确认为一种新的糖苷化促进剂，并成功应用于立体选择性糖苷合成。最终产品通过传统的Zemplén去乙酰化获得。

  Salidroside is a phenylpropanoid glycoside isolated from Rhodiola rosea L., a traditional Chinese medicinal plant, and has displayed a broad spectrum of pharmacological properties. In this paper, about 18 novel salidroside analogues were prepared through Koenigs–Knorr method, the effects of these compounds over PC12 was assessed with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method. The novel compounds differ in the substituents attached to the benzene ring or in the glycosyl donor. According to the data, compounds (3,5-dimethoxyphenyl)methyl β-D-glucopyranoside and (3,5-dimethoxyphenyl)methyl β-D-galactopyranoside with methoxy group at 3 and 5-positions of the benzene ring were the most viability at concentration of 300 μmol/l and 60 μmol/l, respectively.

  红景天苷是从传统中草药红景天中分离得到的一种苯丙素苷类化合物，具有广泛的药理活性。本文通过Koenigs-Knorr方法合成了约18种新颖的红景天苷类似物，并利用3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑溴盐（MTT）法评估了这些化合物对PC12细胞的影响。这些新颖化合物在苯环上的取代基或糖基供体方面有所不同。根据数据，苯环3和5位带有甲氧基的(3,5-二甲氧基苯基)甲基β-D-葡萄吡喃糖苷和(3,5-二甲氧基苯基)甲基β-D-半乳吡喃糖苷在浓度分别为300 μmol/L和60 μmol/L时显示出最高的细胞生存力。

  pharmaceutical demands. Microbial synthetic biology offers promising strategies for synthesis and diversification of plant glycosides. In this study, the two efficient UDP-glucosyltransferases (UGTs) (UGT85A1 and RrUGT3) of plant origin, that are capable of recognizing phenolic aglycons, are characterized in vitro. The two UGTs show complementary regioselectivity towards the alcoholic and phenolic hydroxyl groups

  葡糖苷类天然产物已显示出巨大的药用价值和潜力。然而，通过植物提取、化学合成和传统的生物转化生产糖苷已不足以满足快速增长的制药需求。微生物合成生物学为植物苷的合成和多样化提供了有前景的策略。在这项研究中，能够识别酚苷配基的两种植物来源的高效 UDP-葡萄糖基转移酶 (UGT)（UGT85A1 和 RrUGT3）在体外进行了表征。两种 UGT 对酚类底物上的醇和酚羟基显示出互补的区域选择性。通过将开发的烷基酚生物氧化系统与这些 UGT 相结合，二十四种酚糖苷是由容易获得的烷基酚底物酶促合成的。基于生物氧化和糖基化系统，构建了多个微生物细胞工厂并将其应用于生物转化，产生了多种植物和类植物O-糖苷。值得注意的是，这两种UGTs制备的几种非天然O-糖苷表现出比临床使用的糖苷类药物包括天麻素、红景天苷和螺旋体更好的脯氨酰内肽酶抑制和/或抗炎活性。此外，这两种UGT还能够催化N-和S-糖苷键的形成以产生

  Enzymatic synthesis of various arylalkyl beta-D-glucopyranosides catalyzed by prune (Prunus domestica) seed meal via reverse hydrolysis in the mixture of organic solvent, ionic liquid (IL) and phosphate buffer was described. Among four hydrophilic organic solvents tested, ethylene glycol diacetate (EGDA) was found to be the most suitable for enzymatic synthesis of salidroside, a bioactive compound of commercial interest, from D-glucose and tyrosol. The effects of the nature of ionic liquids and their contents on the enzymatic glucosylation were studied. The addition of a suitable amount of ILs including denaturing ones was favorable to shift the reaction equilibrium toward the synthesis, thus improving the yields. Among the examined ILs, the novel IL [BMIm]I proved to be the best. And this IL was applied as the solvent in biocatalysis for the first time. The yields were found to be enhanced between 0.2-fold and 0.5-fold after the addition of 10% (v/v) [BMIm]I. In 10% (v/v) [BMIm]I-containing system, the desired arylalkyl beta-D-glucopyranosides were synthesized with 15-28% yields, among which salidroside was obtained with a yield of 22%.
