  Synthesis of novel l-rhamnose derived acyclic C-nucleosides with substituted 1,2,3-triazole core as potent sodium-glucose co-transporter (SGLT) inhibitors

  摘要：

  Sodium-glucose co-transporter (SGLT) inhibitors are a novel class of therapeutic agents for the treatment of type 2 diabetes by preventing renal glucose reabsorption. In our efforts to identify novel inhibitors of SGLT, we synthesized a series of L-rhamnose derived acyclic C-nucleosides with 1,2,3-triazole core. The key beta-ketoester building block 4 prepared from L-rhamnose in five steps, was reacted with various aryl azides to produce the respective 1,2,3-triazole derivatives in excellent yields. Deprotection of acetonide group gave the desired acyclic C-nucleosides 7a-o. All the new compounds were screened for their sodium-glucose co-transporters (SGLT1 and SGLT2) inhibition activity using recently developed cell-based nonradioactive fluorescence glucose uptake assay. Among them, 7m with IC50: 125.9 nM emerged as the most potent SGLT2 inhibitor. On the other hand compound 7d exhibited best selectivity for inhibition of SGLT2 (IC50: 149.1 nM) over SGLT1 (IC50: 693.2 nM). The results presented here demonstrated the utility of acyclic C-nucleosides as novel SGLT inhibitors for future investigations. (C) 2014 Elsevier Ltd. All rights reserved.
