first step in the biosynthesis of neuraminic acid, the “epimerisation” of UDP-GlcNAc to ManNAc, is catalyzed by UDP-GlcNAc 2-epimerase. In this paper we report the synthesis of the C-glycosidic UDP-GlcNAc analogues 1−5 as substrate-based inhibitors of this enzyme. The focus is on the optimal distance and geometry of the connection between the sugar and the UDP-moiety, which are both important for recognition
神经氨酸生物合成的第一步,即 UDP-GlcNAc 到 ManNAc 的“差向异构化”,是由 UDP-GlcNAc 2-差向异构酶催化的。在本文中,我们报告了 C-糖苷 UDP-GlcNAc 类似物 1-5 的合成,作为该酶的基于底物的抑制剂。重点是糖和 UDP 部分之间连接的最佳距离和几何形状,这对于 UDP-GlcNAc 2-差向异构酶的识别都很重要。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
