For the enzymatic transfer of galactose, N-acetylglucosamine, and N-acetylgalactosamine, UDP-Gal (1), UDP-GlcNAc (2), and UDP-GalNAc (3) are employed, and UDP serves as a feedback inhibitor. In this paper the synthesis of the novel UDP-sugar analogues 4, 5, and 6 as potential transferase inhibitors is described. Compounds 4-6 feature C-glycosidic hydroxymethylene linkages between the sugar and nucleoside
对于半乳糖,N-乙酰氨基葡糖和N-乙酰半乳糖胺的酶促转移,使用UDP-Gal(1),UDP-GlcNAc(2)和UDP-GalNAc(3),并且UDP用作反馈抑制剂。在本文中,描述了作为潜在转移酶抑制剂的新型UDP-糖类似物4、5和6的合成。与天然衍生物1-3中的异头氧相反,化合物4-6在糖和核苷部分之间具有C-糖苷羟基亚甲基键。
