Biological Activity
IC50: 5.3 nM (KV4.3)[1]
NS5806 (10 μM) induces a 65% increase of KV4.3/KChIP2/DPP6 peak current amplitudes concentration-dependently and the time course of inactivation (τ) is slowed with an EC50 value of 25.4 μM in CHO-K1 cells[1].
NS5806 activates canine transient outward potassium current (Ito) with an IC50 of 40.7 nM and an EC50 of 1.6 nM for inhibition and stimulation on rabbit, respectively[2].
NS5806 (10-100 nM) has concentration-dependent effects on ventricular and atrial Ito[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
