CP-316819
Based on 1 Customer Validation
CP-316819 (GPi 819) is a blood-brain barrier permeable glycogen phosphorylase inhibitor. CP-316819 inhibits hepatic glycogenolysis, safely reduces blood glucose in type 2 diabetes, and rarely induces hypoglycemia. CP-316819 increases brain glycogen reserves, protects neurons, alleviates hypoglycemic brain injury, and inhibits excessive platelet activation, exerting both neuroprotective and vasculoprotective effects. CP-316819 can be used in research related to hypoglycemia, thrombosis, autoimmune inflammatory diseases, and type 2 diabetes.

Biological Activity
CP-316819 (50 μM; 0-20 minutes) transiently inhibits the early α-granule exocytosis of thrombin-stimulated control mouse platelets, and exocytosis returns to normal at 20 minutes after stimulation[2].
CP-316819 (0-1 mM; 24 h) increases glycogen content in primary Swiss-Webster mouse forebrain astrocyte cultures in a dose-dependent manner, without preventing glycogen utilization during glucose deprivation[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
CP-316819 (initial dose of 150 mg/kg, followed by 50 mg/kg at 12 h and 16 h after the initial administration; intraperitoneal injection) increases brain glycogen content in rats and prolongs the duration of neuronal activity under hypoglycemic conditions[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:Sprague-Dawley (adult male, 2-3 months of age, insulin-induced hypoglycemia model)[1]
-
Dosage:2.5 mg/24 h; 10.0 mg/24 h
-
Administration:i.c.v.; continuous infusion; 24 hours

Result:Elevated basal glycogen only in the lateral hypothalamic area (LHA) at 2.5 mg/24 h dose; insulin-induced hypoglycemia reduced VMN and LHA glycogen in this group.
Elevated basal glycogen in the VMN, arcuate hypothalamic nucleus (ARH), dorsomedial hypothalamic nucleus (DMN), and LHA at 10.0 mg/24 h dose; insulin-induced hypoglycemia further increased glycogen in all these regions.
Elevated basal glucose in the VMN, ARH, and LHA, and prevented hypoglycemic glucose reduction in the ARH and DMN at 2.5 mg/24 h dose.
Reduced basal glucose in the LHA and DMN, and prevented hypoglycemic glucose reduction in the ARH, LHA, and DMN at 10.0 mg/24 h dose.
Elevated basal GAD65/67 and phosphorylated AMPK (pAMPK) levels in VMN GABA neurons at 2.5 mg/24 h dose; hypoglycemia reversed these increases to baseline levels.
Had no effect on basal GAD65/67, Fos, AMPK, or pAMPK levels in VMN GABA neurons, and prevented hypoglycemic increases in these proteins at 10.0 mg/24 h dose.
Reduced basal SF-1, Fos, AMPK, and pAMPK levels in VMN SF-1 neurons at 2.5 mg/24 h dose; hypoglycemia did not alter these reduced levels.
Reduced basal Fos, AMPK, and pAMPK levels (with no change to SF-1) in VMN SF-1 neurons at 10.0 mg/24 h dose; hypoglycemia did not alter these levels.
Prevented hypoglycemic AMPK activation in VMN SF-1 neurons at both doses.
Elevated basal neuronal nitric oxide synthase (nNOS), Fos, AMPK, and pAMPK levels in VMN nitrergic neurons at 2.5 mg/24 h dose; hypoglycemia increased nNOS further but reduced Fos, AMPK, and pAMPK to baseline.
Elevated basal nNOS and Fos levels (with no change to AMPK or pAMPK) in VMN nitrergic neurons at 10.0 mg/24 h dose; hypoglycemia reduced nNOS, Fos, and pAMPK levels from baseline.
Elevated basal plasma glucagon levels at 2.5 mg/24 h dose; hypoglycemia reduced glucagon to below baseline.
Had no effect on basal glucagon at 10.0 mg/24 h dose; hypoglycemia did not alter glucagon levels.
Did not affect plasma corticosterone levels at either dose.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (5.00 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
