With its remarkable selectivity, CP-91149 stands out as a potent inhibitor of glycogen phosphorylase (GP). In the presence of glucose, it demonstrates an impressive IC50 value of 0.13 μM, effectively impeding GP activity. However, its potency decreases when glucose is absent, showing 5- to 10-fold lower inhibitory efficacy. This distinctive behavior highlights the dependency of CP-91149′s effectiveness on the presence of glucose.
