  摘要：

  The synthesis and structure-activity-relationships (SARs) of novel 2-(pyridine-2-yl)-1H-benzimidazole glucokinase activators are described. Systematic modi. cation of benzimidazole lead 5a identified from a high-throughput screening led to the discovery of a potent and metabolically stable glucokinase activator 16p(R) with greater structural diversity from GKAs reported to date. The compound also demonstrated acute oral glucose lowering efficacy in rat OGTT model. (C) 2009 Elsevier Ltd. All rights reserved.
