Clear solution
5% DMSO 95% Corn oil
0.437mg/ml Taking the 1 mL working solution as an example, add 50 μL of 8.74 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
0.875mg/ml Taking the 1 mL working solution as an example, add 50 μL of 17.5 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description SC75741 is a potent NF-κB inhibitor with EC50 of 200 nM. SC75741 efficiently blocks influenza virus propagation.
Targets
NF-κB [1]
(Cell-based NF-κB reporter gene assay)
200 nM(EC50)
In vitro SC75741 shows immunosuppressive activity by inhibiting human PBMC proliferation with IC50 of 2.2 μM. [1] SC75741 inhibits replication of influenza A and B viruses by inhibiting NF-κB-mediated signalling on a transcriptional level. Moreover, SC75741 shows a high barrier for development of resistant virus variants. [2]
In vivo SC75741 (15 mg/kg i.p.) reduces virus replication and cytokine expression in mice lungs after H5N1 influenza virus infection. [2]
Features NF-κB-selective inhibitor.

Protocol (from reference)

Kinase Assay:[1]
  • NF-κB reporter gene assay

    The NF-κB reporter gene assay is prepared with A549-NF-κB-SEAP cell line according to manufacturer’s instructions. In short, A549 cells stably transfected with pNF-κB-SEAP reporter gene plasmid are plated and allowed to attach overnight. The cells are subsequently incubated for 5 h with described compounds at 100, 30, 10, 3, 1, 0.3, 0.1, and 0 μM and then stimulated with 10 ng/ml TNF-α for 22 h. The supernatant of the cell is analyzed for SEAP activity using a chemiluminescent SEAP reporter gene assay.
Cell Assay:[1]
  • Cell lines

    Human PBMCs

  • Concentrations

    ~50 μM

  • Incubation Time

    48 hours

  • Method

    Cell viability assay is prepared using a CellTiter-BluTM Cell Viability Assay. For each concentration of the compound four replicates are measured.
Animal Study:[2]
  • Animal Models

    C57BL/6 mice infected with H5N1 influenza virus

  • Dosages

    ~15 mg/kg

  • Administration

    i.p.
