SAR, pharmacokinetics, safety, and efficacy of glucokinase activating 2-(4-sulfonylphenyl)-N-thiazol-2-ylacetamides: Discovery of PSN-GK1

Allosteric activators of the glucose-sensing enzyme glucokinase (GK) are currently attracting much interest as potential antidiabetic therapies because they can achieve powerful blood glucose lowering through actions in multiple organs. Here, the optimization of a weakly active high-throughput screening hit to (2R)-2-(4-cyclopropanesulfonylphenyl)-N-(5-fluorothiazol-2-yl)-3- (tetrahydropyran-4-yl)propionamide (PSN-GK1), a potent GK activator with an improved pharmacokinetic and safety profile, is described. Following oral administration, this compound elicited robust glucose lowering in rats.
