  α-Bromophosphonate analogs of glucose-6-phosphate are inhibitors of glucose-6-phosphatase

  摘要：

  Glucose-6-phosphatase (G6Pase) is an essential metabolic enzyme that has upregulated activity in Type II diabetes. Synthetic analogs of the G6Pase substrate, glucose-6-phosphate (G6P), may provide new tools to probe enzyme activity, or lead to specific inhibitors of glycosylphosphatase enzymes. Here we have developed synthetic routes to a panel of non-hydrolyzable G6P analogs containing alpha-bromo,alpha,alpha-dibromo, and alpha-bromo-alpha, beta-unsaturated phosphonates compatible with a carbohydrate nucleus. We confirm that these functionalities have potency as inhibitors of G6Pase in vitro, providing a series of new phosphate isosteres that can be exploited for inhibitor design. (C) 2013 Elsevier Ltd.

  日期：——

  A direct oxidative radical decarboxylative cyanomethylation of carboxylic acids is described using 3-azido-2-methylbut-3-en-2-ol as the carbon-centered radical acceptor. The transformation is applicable to structurally diverse α-amino acids, α-oxy acids, α-keto acids, pentofuranuronic acids, and hexopyranuronic acids. The mechanistic investigations suggest that a radical process is involved in the

  Eight nitrogen heterocycles, mono and disubstituted tetrazoles and oxadiazoles, were synthesized from methyl D-glucopyranoside anomers. The monosubstituted tetrazoles resulted from the reaction of 6-cyanoglucopyranoside derivatives with sodium azide. By alkylation of the monosubstituted tetrazoles, the 1,5 and 2,5 disubstituted tetrazoles were obtained. The monosubstituted tetrazoles were reacted with acetic anhydride to give the oxadiazoles.
