  Design and synthesis of C-linked fucosides as inhibitors of E-selectin

  摘要：

  Two series of C-linked fucosides as mimetics for the tetrasaccharide sialyl Lewis X have been synthesized and tested as inhibitors of E-Selectin. The fucopeptides have been prepared from three key intermediates, including alpha-C-allyl fucose, natural and unnatural amino acids bearing hydroxyl groups and an alpha,omega-diacid moiety for the imitation of the essential three parts of SLe(x), i.e., the Fuc, Gal, and NeuAc. The nature and distance of the linkage of the fucose moiety to the amino acids as well as the distance between the amino acids and the terminal carboxylic acid group turned out to be crucial for the biological activity. In addition the necessity of both OH groups (4- and 6-OH) in the Gal part could be confirmed. Conformational NMR study of the most active mimetic supports the structure-activity relationship. A second series of mimetics was prepared, where Fuc and Gal moieties were purely C-linked. In the synthesis of beta-C-allyl galactose an intramolecular 1,2-hydride shift led to an interesting side product. However, the substituted glycosidic oxygens led to a substantial loss of conformational constrain, which could not be compensated and resulted in low activity.

• C-Fucopeptides as selectin antagonists: Attachment of lipid moieties enhances the activity
  作者：Thomas J. Woltering、Gabriele Weitz-Schmidt、Chi-Huey Wong

  DOI：10.1016/s0040-4039(96)02121-1

  日期：1996.12

  The biological activity of a potent selectin antagonist could be 40-fold enhanced by attachment of a lipid moiety. Also an enantioselective synthesis of beta,omega-dihydroxyamino acids by Sharpless asymmetric dihydroxylation (AD-reaction) allowed general access to this important class of compounds.
