  Small molecule glycoconjugates with anticancer activity

  摘要：

  Glycoconjugates are combinations of sugar moieties with organic compounds. Due to their biological resemblance, such structures often have properties that are desirable for drugs. In this study we designed and synthesised several glycoconjugates from small molecular quinolines and substituted gluco- and galactopyranosyl amines. Although the parent quinoline compounds were inactive in affordable concentrations, the glycoconjugates that were obtained appeared to be cytotoxic against cancer cells at the micromolar level. When combined with copper ions, their activity increased even further. Their mechanism of action is connected to the formation of reactive oxygen species and the intercalation of DNA.

• Formation and stability of oxocarbenium ions from glycosides
  作者：Chagit Denekamp、Yana Sandlers

  DOI：10.1002/jms.880

  日期：2005.8

  in the formation of oxocarbenium intermediates were studied in the gas phase. It is found that significant stabilization of oxocarbenium cations is achieved by protecting groups that interact with the cationic center via neighboring group participation despite the electron-withdrawing character of these moieties. On the other hand, ethereal protecting groups do not facilitate the formation of oxocarbenium

  在气相中研究了氧碳intermediate中间体的形成中的结构，保护基和离去基团的作用。发现尽管这些部分具有吸电子特性，但通过保护经由相邻基团参与而与阳离子中心相互作用的基团，可以实现氧碳鎓阳离子的显着稳定。另一方面，醚保护基不促进氧碳en中间体的形成。DFT计算支持了实验结果，DFT计算显示了与阳离子中心相邻的基团的稳定顺序如下：RCO> SiR（3）> R，其中R为烷基。这表明通常为该反应提出的类似于SN1的机制并不总是有效的。

• Thio-arylglycosides with various aglyconpara-substituents: a probe for studying chemical glycosylation reactions

  indicates that the glycosylation mechanism remains the same over a wide range of reactivities and glycosylation conditions. The negative slopes of the Hammett plots suggested that electron donating substituents expedite the reactions and the magnitudes of slopes can be rationalized by neighboring group participation as well as electronic properties of the glycon protective groups.

  日期：2013.2.1

  α- and β-thioglycosides serve as effective nucleophiles for Buchwald–Hartwig cross-coupling reactions using functionalized (hetero)aryl halides. The functional group tolerance on the electrophilic partner is typically high, both benzyl and acetate protecting groups on the carbohydrate are tolerated, and anomer selectivities of thioglycosides are high in all cases studied. The efficiency of this general
