Description

NF-κB-IN-1, a 4-arylidene crucumin analogue, is a potent NF-κB signaling pathway inhibitor. NF-κB-IN-1 directly inhibits IKK to block NF-κB activation. NF-κB-IN-1 effectively inhibits the viability of lung cancer cells and attenuates the clonogenic activity of A549 cells[1].

IC50 & Target

IKK[1]
In Vitro

NF-κB-IN-1 (compound 17) (0.001-100 μM; 72 h) inhibits the growth of A549, H1944, H460 and H157 cells, with GI50s of 0.72, 0.07, 0.13, and 0.16 μM, respectively[1].
NF-κB-IN-1 (0.5-25 μM; pretreated for 30 min or 4 h) potently blocks the IκB phosphorylation and degradation in A549 cells[1].
NF-κB-IN-1 (0.1-100 μM; pretreated for 30 min) dose-dependently inhibits the TNFα-induced nuclear translocation of NF-κB in A549 cells, with an IC50s of 1.0 μM[1].
NF-κB-IN-1 (0.1-0.4 μM; 9 d) inhibits lung cancer clonogenic activity[1].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (4.71 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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
