  New synthesis of 3-(β-D-glucopyranosyl)-5-substituted-1,2,4-triazoles, nanomolar inhibitors of glycogen phosphorylase

  摘要：

  O-Perbenzoylated 5-(beta-D-glucopyranosyl)tetrazole was reacted with N-benzyl carboximidoyl chlorides to give the corresponding 4-benzyl-3-(beta-D-glucopyranosyl)-5-substituted-1,2,4-triazoles. Removal of the O-benzoyl and N-benzyl protecting groups by base catalysed transesterification and catalytic hydrogenation, respectively, furnished a series of 3-(beta-D-glucopyranosyl)-5-substituted-1,2,4-triazoles with aliphatic, mono- and bicyclic aromatic, and heterocyclic substituents in the 5-position. Enzyme kinetic studies revealed these compounds to inhibit rabbit muscle glycogen phosphorylase b: best inhibitors were the 5-(4-aminophenyl)- (K-i 0.67 mu M) and the 5-(2-naphthyl)-substituted (K-i 0.41 mu M) derivatives. This study uncovered the C-glucopyranosyl-1,2,4-triazoles as a novel skeleton for nanomolar inhibition of glycogen phosphorylase. (C) 2014 Elsevier Masson SAS. All rights reserved.

  C-Glucopyranosyl-1,2,4-triazoles As New Potent Inhibitors of Glycogen Phosphorylase

  摘要：

  Glycogen phosphorylase inhibitors are considered as potential antidiabetic agents. 3-(beta-D-Glucopyranosyl)-5-substituted-1,2,4-triazoles were prepared by acylation of O-perbenzoylated N-1-tosyl-C-beta-D-glucopyranosyl formamidrazone and subsequent removal of the protecting groups. The best inhibitor was 3-(beta-D-glucopyranosyl)-5-(2-naphthyl)-1,2,4-triazole (K-i = 0.41 mu M against rabbit muscle glycogen phosphorylase b).

  Bromination of the so obtained compounds by NBS gave hydrazonoyl bromide type derivatives which were ring closed to 3-C-glycosyl-5-substituted-1,2,4-triazoles in pyridine or by NH4OAc in AcOH. Under the same conditions O-perbenzoylated N1-arylidene-C-(β-D-glucopyranosyl)-formamidrazones gave the expected 1,2,4-triazoles as minor products only. N1-Arylidene-arenecarboxamidrazones were also transformed

  在具有多种生物活性的1,2,4-三唑衍生物中，3 - C-吡喃葡萄糖基-5-取代的1,2,4-三唑属于糖原磷酸化酶的最有效抑制剂，因此是潜在的降糖药。在寻找用于这类化合物的新的合成方法中，研究了N 1-亚烷基羧酰胺dra的氧化性闭环。在NaH 2 PO 2存在下，通过Raney-Ni®还原反应，由相应的糖基氰化物和酰氨基prepared酰胺制备O-酰化的N 1-（β- D-甘氨酸金烷基糖基亚甲基）-芳族羧酰胺基酮。通过NBS对如此获得的化合物进行溴化得到了酰肼基溴化物型衍生物，其在吡啶中或在AcOH中通过NH 4 OAc与3- C-糖基-5-取代-1,2,4-三唑闭环。在相同条件下ø -perbenzoylated Ñ 1 -arylidene- Ç - （β- d吡喃葡萄糖基）-formamidrazones给出预期的-1,2,4-三唑作为只有轻微的产品。N 1-亚芳基-亚芳基甲酰胺还与NBS
