In Vitro
SC-514 inhibits the native IKK complex or recombinant human IKK-1/IKK-2 heterodimer with IC50s of 6.1±2.2 μM and 2.7±0.7 μM, respectively. IKK-2 inhibition by SC-514 is selective, reversible, and competitive with ATP. SC-514 inhibits transcription of NF-κB-dependent genes in IL-1β-induced rheumatoid arthritis-derived synovial fibroblasts in a dose-dependent manner. SC-514 inhibits all forms of recombinant human IKK-2 including rhIKK-2 homodimer, rhIKK-1/rhIKK-2 heterodimer, as well as the constitutively active form of rhIKK-2 with comparable IC50 values in the 3-12 μM range[1]. To evaluate whether the reactive oxygen species (ROS)-inducing IKKβ inhibitor increases the sensitivity of melanoma cells to nitrosourea. The responses of melanoma cells are first assessed to SC-514/Fotemustine co-treatment. Melanoma cell lines are treated with 50 μM of SC-514 and Fotemustine alone and in combination for 48 h and growth inhibition is assessed. Co-treatment with SC-514 significantly enhances Fotemustine-induced cytotoxicity in all melanoma cell lines tested[2].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (11.15 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 (11.15 mM); Clear solution
