Carbenoxolone is a blood-brain barrier-permeable Pannexin1 inhibitor, gap junction (Gap junction) blocker, and β-amyloid 42 inhibitor. Carbenoxolone modulates voltage-gated currents of wild-type and mutant Panx1, and inhibits stimulus-activated Panx1 channel function. Carbenoxolone interacts with stable residues of β-amyloid 42 peptides, fibrils and oligomers, thereby inhibiting their aggregation. Carbenoxolone alleviates liver fibrosis. Carbenoxolone exerts neuroprotective and nootropic effects. Carbenoxolone can be used in studies related to Alzheimer's disease and liver fibrosis.

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.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (4.38 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
