Biological Activity
EC50: 10.5 μM (hERG) K+ channel[1]
NS1643 (0-100 μM) dose- and voltage-dependently increases hERG current in oocytes[1]. NS1643 (3, 10 and 30 μM) slows the rate of hERG inactivation throughout the testing voltage range and reduces the extent of hERG channel rectification[1]. NS1643 (10 and 50 μM) dose-dependently inhibits cell migration and invasion of MDA-MB-231 and SKBR3 cancer cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:MDA-MB-231, SKBR3 and MCF7 breast cancer cell lines
-
Concentration:50 μM
-
Incubation Time:24 h
-
Result:Decreased Vimentin, N-cadherin and CD44 levels, and increased E-cadherin in breast cancer cell lines.

-
Animal Model:NSG mice with human-derived TNBC tumor xenografts[2]
-
Dosage:6 mg/kg
-
Administration:Intraperitoneal injection; 6 mg/kg; twice per week
-
Result:Significantly reduceed tumor growth and the metastatic liver tumors were significantly smaller than those in the control group. Decreased levels of human nuclear antigen (HNA).

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.57 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.57 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
