Biological Activity

Potent Nav1.7 blocker (IC50 = 2.5 nM). Also inhibits Nav1.1, Nav1.2, Nav1.3 and Nav1.6 in the nanomolar range. Exhibits no effects on Cav channels or nAChR at 5 μM. Demonstrates analgesic activity in vivo; antagonizes effects of scorpion-venom toxin OD1 at Nav1.7.

Preparing Stock Solutions

The following data is based on the product molecular weight 3802.41. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 0.26 mL 1.31 mL 2.63 mL
5 mM 0.05 mL 0.26 mL 0.53 mL
10 mM 0.03 mL 0.13 mL 0.26 mL
50 mM 0.01 mL 0.03 mL 0.05 mL
