Zatebradine hydrochloride (UL-FS-49CL) is a highly effective and effective HCN Channel inhibitor (IC50:1.96 µM). HCN Channel is an effective hyperpolarization activated loop nucleotide gated channel. Zatebradine hydrochloride blocks slow inward currents through human HCN1, HCN2, HCN3, and HCN4 channels with IC50 values of 1.83 µM, 2.21 µM, 1.90 µM, and 1.88 µM, respectively.

DMSO/H2O
| ||||||||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
