1 Customer Review
Renal Nrf2 activity was shown in RTA402-treated acFSGS (RTA402 + acFSGS) mice as early as day 7 (RTA402 + acFSGS) and persisted to day 28, compared to vehicle + acFSGS mice. Kidney in situ ROS production demonstrated by DHE detection.

|Description||Bardoxolone Methyl is an IKK inhibitor, showing potent proapoptotic and anti-inflammatory activities; Also a potent Nrf2 activator and nuclear factor-κB (NF-κB) inhibitor.|
|Features||The only IKKβ inhibitor in clinical use for solid tumors, type 2 diabetes, and chronic kidney disease. An orally-available antioxidant inflammation modulator.|
Bardoxolone Methyl exhibits potent inhibitory activities against production of nitric oxide induced by interferon-Ƴ in mouse macrophages with IC50 of 0.1 nM.  Bardoxolone Methyl decreases the viability of leukemic HL-60, KG-1, and NB4 cells with IC50 of 0.4, 0.4, and 0.27 μM, respectively. CDDO-Me induces pro-apoptotic Bax protein, inhibits the activation of ERK1/2, and it blocks Bcl-2 phosphorylation, which contributes to the induction of apoptosis.  Bardoxolone Methyl potently inhibits both constitutive and inducible NF-kappaB activated by TNF, interleukin (IL)-1beta, phorbol ester, okadaic acid, hydrogen peroxide, lipopolysaccharide, and cigarette smoke. 
|In vivo||Bardoxolone Methyl (60 mg/kg) reduces the number, size, and severity of lung tumors in vivo.  Bardoxolone Methyl significantly reduces the in vivo inflammatory cytokine response following LPS challenge, induces HO-1 protein expression in the spleen, and protects mice against lethal-dose LPS. |
IKK assay :To determine the effect of CDDO-Me on TNF-induced IKK activation, IKK is analyzed. Briefly, the IKK complex from whole-cell extracts was precipitated with antibody against IKKα and IKKβ and then treated with protein A/G-Sepharose beads. After 2 hours, the beads are washed with lysis buffer and then resuspended in a kinase assay mixture containing 50 mmol/L HEPES (pH 7.4), 20 mmol/L MgCl2, 2 mmol/L DTT, 20 μCi [γ-32P]ATP, 10 μmol/L unlabeled ATP, and 2 μg of substrate glutathione S-transferase-IκBα (amino acids 1-54). After incubation at 30°C for 30 minutes, the reaction is terminated by boiling with SDS sample buffer for 5 minutes. Finally, the protein is resolved on 10% SDS-PAGE, the gel is dried, and the radioactive bands are visualized with a Storm820. To determine the total amounts of IKK-α and IKK-β in each sample, 50 μg of whole-cell proteins are resolved on 7.5% SDS-PAGE, electrotransferred to a nitrocellulose membrane, and then blotted with either anti-IKK-α or anti-IKK-β antibody.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
