    Background
    
    CP-91149 is a selective inhibitor of glycogen phosphorylase (GP) with an IC50 value of 0.13 μM.
    Glycogen phosphorylase is a phosphorylase enzymes that can catalize phosphorolytic cleavage of the glycosidic linkages of glycogen by releasing glucose-1-phosphate from the terminal alpha-1, 4-glycosidic bond. It controls the rate-limiting step in glycogenolysis in the cells.
    In vitro, CP-91149 treatment suppressed glycogenolysis stimulated by glucagon in in primary human hepatocytes and isolated rat hepatocytes with IC50 value of 2.1 μM and 10–100 μM, respectively 1. Inhibition of phosphorylase a by CP-91149 resulted in activation of glycogen synthase and translocation of the protein from a soluble to a particulate fraction, which mimicked the insulin- stimulated glycogen synthesis 2.
    In vivo, treatment of CP-91149 on diabetic ob/ob mice at a dosage of 25–50 mg/kg was shown to lead to a rapid glucose lowering but did not change glucose levels in normoglycemic, nondiabetic mice 1.
