Product Description

Raxatrigine (also known as GSK-1014802 and CNV-1014802) is a novel, potent small molecule state-dependent sodium channel blocker, the Nav1.7 sodium channel inhibitor. It has the potential to be used as an analgesic and is being developed by Convergence Pharmaceuticals for the treatment of lumbosacral radiculopathy (sciatica) and trigeminal neuralgia (TGN).

Biological Activity I Assay Protocols (From Reference)

ln Vitro	GSK2 and GSK3 have the same ability to stop PCP-induced reversal learning deficits as lamotrigine, indicating that they may be used to treat cognitive symptoms of schizophrenia. Nonetheless, greater dosages than those needed for the medication's anticonvulsant efficacy are necessary for the reversal learning model to be active, indicating a narrow therapeutic window in comparison to the mechanism-dependent central adverse effects of this indication. The US Food and medicine Administration designated raxatrigine (GSK-1014802) as an orphan medicine in July 2013.

*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.

Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?

Enter 350.26 in the Molecular Weight (MW) box
Enter 10 in the Concentration box and choose the correct unit (mM)
Enter 5 in the Volume box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.
