Efforts to enhance the inhibitory potency of the initial purine series of fructose-1,6-bisphosphatase (FBPase) inhibitors led to the discovery of it series of benzirniclazole analogues with hurnan FBPase IC50S < 100 nM. I nhibitor 4.4 emerged as a lead compound based on its potent inhibition of hurnan liver FBPase (IC5() = 55 ilM) and significant glucose lowering in nornial fasted rats. Intravenous administration of 4.4 to Zucker diabetic fatty rats led to rapid and robust glucose lowering, thereby providing the first evidence that FBPase inhibitors could improve glycernia in animal models of type 2 diabetes.
