Biological Activity

Description SC75741 is a potent NF-κB inhibitor with EC50 of 200 nM. SC75741 efficiently blocks influenza virus propagation.
Features NF-κB-selective inhibitor.
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]

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 Research:[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 Research:[2]
  • Animal Models: C57BL/6 mice infected with H5N1 influenza virus
  • Dosages: ~15 mg/kg
  • Administration: i.p.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
