  作为唾液酸化的路易斯X模拟物的新型6-酰胺基-6-脱氧-1-半乳糖衍生物的合成。

  摘要：

  描述了几种唾液酸化的路易斯X（SLe（x））模拟物的合成和生物效能。这些模拟物结合了SLe（x）中存在的与E-选择素结合所必需的所有关键功能基团。由于2-，3-和4-羟基的相同排列，L-半乳糖用于模拟SLe（x）中天然存在的L-岩藻糖残基。几种合成和酶促制备的氨基酸用于模拟D-半乳糖残基。由于这些氨基酸合成中的可变性，研究了有效结合所必需的空间要求。引入带有羧酸盐的侧链作为唾液酸模拟物，并改变链长以最大化生物学活性。

  been developed as sialyl Lewis X mimetics. Although the compounds have a much simpler structure compared to SLe(x), up to 3-times higher binding affinity toward E-selectin and > 1000 times toward P-selectin was observed. Furthermore, a convenient strategy for generating a number of analogues from a SLe(x) mimetic template at a very late stage of the synthesis was introduced, using a ruthenium catalyzed

  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. Copyright (C) 1996 Elsevier Science Ltd
