CP 91,149 is a novel, potent and selective inhibitor of human liver glycogen phosphorylase a (LGPa) with IC50 of 0.13 μM in the presence of glucose, 5- to 10-fold less potent in the absence of glucose. It also inhibits muscle glycogen phosphorylase a (MGPa), and MGPb (IC50s = 0.13, 0.2, and 0.3 μM, respectively, in the presence of glucose. CP 91,149 is 5- to 10-fold less potent in the absence of glucose. In vitro, it inhibits glucagon-stimulated glycogenolysis in primary human hepatocytes (IC50 = 2.1 μM) and increases glycogen synthesis in rat hepatocytes at a concentration of 2.5 μM in the presence of 5 mM glucose. CP 91,149 inhibits brain GP (IC50 = 0.5 μM) and, at a concentration of 30 μM, inhibits glycogen accumulation and proliferation of A549 non-small cell lung carcinoma (NSCLC) cells that express endogenous brain GP. In vivo, CP 91,149 (25 mg/kg, p.o.) lowers the plasma glucose level in diabetic ob/ob mice within 3 hours of administration without producing hypoglycemia, but has no effect on normoglycemic, non-diabetic mice. CP-91149 is a selective glycogen phosphorylase (GP) inhibitor with IC50 of 0.13 μM in the presence of glucose, 5- to 10-fold less potent in the absence of glucose.
| ln Vitro |
By blocking AMP-mediated GP b activation and converting the phosphorylated AMP-independent α form of muscle GP activity to the dephosphorylated AMP-dependent b form, CP-91149 therapy lowers muscle GP activity [1]. In A549 cells, CP-91149 (10, 30, 50 μM) inhibits brain GP and results in a buildup of glycogen [2].

| Cell Assay |
Cell Viability Assay[1]
Cell Types: Cells were transduced with adenovirus and incubated in the presence of 25 mM glucose for 2 days. Tested Concentrations: 10 µM (glucose− or glucose+ for 18 hrs (hours)). Incubation Duration: 3 hrs (hours). Experimental Results: Conversion of GP a to GP b was promoted according to the proposed α model in hepatocytes. Western Blot Analysis[2] Cell Types: A549 cells. Tested Concentrations: 0, 10, 30, 50 μM. Incubation Duration: 72 hrs (hours). Experimental Results: A significant increase in glycogen accumulation was detected with 10 μM CP-91149 compared to untreated cells (maximum glycogen accumulation was 30 μM). At a concentration of 50 μM CP-91149, intracellular glycogen content was diminished, which may be due to other pharmacological effects of the drug. CP-91149 Dose-dependent accumulation of intracellular glycogen in A549 cells indicates that CP-91149 inhibits brain GP in tissue culture. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.25 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.25 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
