Abstact

The optimization of a series of benzimidazole glucokinase activators is described. We identified a novel and potent achiral benzimidazole derivative as an allosteric GK activator. This activator was designed and synthesized via removal of the chiral center of the lead compound, 6-(N-acylpyrrolidin-2-yl)benzimidazole. The activator exhibited good PK profiles in rats and dogs, and significant hypoglycemic efficacy at 1 mg/kg po dosing in a rat OGTT model. The binding site and binding mode of the benzimidazole class of GKA with GK protein was confirmed by X-ray crystallographic analysis.
