NS-1619
Based on 4 publication(s) in Google Scholar
NS-1619 is an opener of large conductance Ca2+-activated K+ (BK) channel. NS-1619 is a highly effective relaxant with an EC50 of about 10 – 30 μM in several smooth muscles of blood vessels and other tissues. NS1619 inhibits proliferation and induces apoptosis in A2780 ovarian cancer cells.

Biologische Aktivität
NS1619 (5, 10, 30, 50, and 100 μM) inhibits the proliferation of A2780 cells in a dosage and time dependent manner IC50=31.1 μM for 48 h pretreatment[2].
NS1619 (30 μM) exhibits augmenting effect on whole cell IK in human ovarian cancer cells A2780[2].
NS1619 (10, 30, 50, and 100 μM) increases levels of p53, p21Cip1 and Bax proteins in A2780 cells[2].
DNA content of A2780 cells was significantly decreased after 36 and 48 h of pretreatment. The breakdown of DNA results in death of the tumor cells[2].

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 (6.90 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)
