  UDP-Glucose Analogues as Inhibitors and Mechanistic Probes of UDP-Glucose Dehydrogenase

  摘要：

  UDP-glucose dehydrogenase catalyzes the NAD(+)-dependent 2-fold oxidation of UDP-glucose to give UDP-glucuronic acid. The putative aldehyde intermediate is not released from the active site and is presumably tightly bound. We have prepared UDP-7-deoxy-alpha-D-gluco-hept-6-ulopyranose 5, that contains a methyl ketone at C-6 and cannot be further oxidized by the enzyme. Ketone 5 was found to be a competitive inhibitor of the dehydrogenase from Streptococcus pyogenes with a K-I value of 6.7 mu M. We have also prepared the secondary alcohols UDP-6S-6C-methylglucose, 4a, and UDP-6R-6C-methylglucose, 4b. Compound 4a, but not 4b, was found to be a slow substrate for the dehydrogenase and was converted into the ketone inhibitor 5. This is consistent with the notion that the pro-R hydride is transferred in the first oxidation step of the normal enzymatic reaction.

  D-葡萄糖和L-岩藻糖的7-碳模拟物：糖原合酶的6R-激活和6S，-6C-甲基葡萄糖的失活：葡萄糖激酶和/或葡萄糖-6-磷酸酶的抑制

  摘要：

  描述了差向异构的C 6 -C-甲基葡萄糖的短效合成。一个C-6差向异构体激活糖原合酶，而另一个差向异构体失活该酶。C 6 R -C-甲基葡萄糖3是葡萄糖6磷酸酶的特异性抑制剂的第一个实例，并且可以使细胞内葡萄糖6磷酸的浓度增加20倍。C 6 S -C-甲基葡萄糖2抑制葡萄糖激酶和葡萄糖6-磷酸酶，但也具有容易获得L-岩藻糖的α - C-糖苷的潜力。C-6-烷基碳水化合物可提供一系列新的糖模拟物，以控制与糖-6-磷酸的形成，水解和其他命运相关的酶。
