  • Dually Enzyme- and Acid-Triggered Self-Immolative Ketal Glycoside Nanoparticles for Effective Cancer Prodrug Monotherapy
    作者:Na Yu、Tao Liu、Xi Zhang、Ningqiang Gong、Tianjiao Ji、Jing Chen、Xing-Jie Liang、Daniel S. Kohane、Shutao Guo

    Amphiphilic glucosyl acetone-based ketal-linked etoposide glycoside prodrug isomers were synthesized and fabricated into excipient-free nanoparticles for effective cancer prodrug monotherapy. Hydrolysis of the glycosidic linkage or the ketal linkage triggered hydrolysis of the other linkage, which resulted in spontaneous self-immolative hydrolysis of the prodrugs. Nanoparticles of the prodrug isomer that
    使用糖苷前药是开发用于化疗的新靶向药物的有前途的策略。但是,体内由于活化不足和缺乏方便的合成方法,阻碍了这种前药的实用性。我们已经开发出了一种合成缩酮缩糖苷前药的创新策略,该缩酮糖苷前药在通过双重酶和酸触发的自消灭机制中被激活是独特的。合成基于两亲葡糖基丙酮的缩酮连接的依托泊苷糖苷前药异构体,并将其制备成不含赋形剂的纳米颗粒,以有效地进行癌症前药单药治疗。糖苷键或缩酮键的水解引发另一个键的水解,这导致前药的自发自焚水解。在溶酶体模拟环境中最不稳定的前药异构体的纳米颗粒在A549异种移植小鼠模型中显示出较高的肿瘤内蓄积和强大的抗肿瘤活性。我们的策略可能对刺激反应性自焚前药及其纳米药物的开发有用。

Elimination reactions of 2-(phenylselenyl)ethyl glycosides and 2(trimethylammonium)-ethyl glycosides, and photolysis of 4-oxopentyl glycosides by Norrish Type II reactions also give vinyl glycosides.

The glycosylidene carbenes, derived from 1 or 13 are not very reactive towards ketones, yields are good only when sterically unhindered ketones are used in large excess.

  • Isopropenyl glycosides and congeners as novel classes of glycosyl donors: theme and variations
    作者:Alberto Marra、Jacques Esnault、Alain Veyrieres、Pierre Sinay
    DOI:10.1021/ja00042a010
    日期:1992.7
    Isopropenyl glycosides (i.e., 10 and 11) have been synthesized in high yields by reacting the corresponding anomeric acetates with the Tebbe reagent. These compounds undergo glycosylation with primary or secondary carbohydrate alcohols in the presence of trimethylsilyl triflate or boron trifluoride etherate, probably via a mixed acetal glycoside intermediate. On the basis of this principle, a quite efficient glycosylation of monosaccharide hemiacetal donors (i.e., 1, 7, and 9) with acceptors bearing an isopropenyl ether function at a primary or secondary position (i.e., 18 and 21) has been developed. Also investigated were the glycosylating properties of isopropenyl glucosyl and galactosyl carbonates (i.e., 12-15), easily prepared from the corresponding hemiacetals, toward sugar alcohols. In each case, the beta-selective synthesis of disaccharides from donors having nonparticipating groups at C-2 was ensured by the use of acetonitrile, at low temperature, as the solvent.
  • Synthesis of cyclopropyl glycosides and their use as novel glycosyl donors

    Methods for the synthesis of cyclopropyl glycosides and their use as glycosyl donors are described. Cyclopropyl glycosides containing different substituents were prepared by cyclopropanation of the corresponding vinyl glycosides, or by glycosidation of cyclopropyl alcohols that are synthesized by the Kulinkovich reaction. 1-Methyl- and 1-phenyl-substituted cyclopropyl glycosides undergo coupling to
