Verkningsmekanism (Mechanism of Action)

Egenskaper
The only IKKβ inhibitor in clinical use for solid tumors, type 2 diabetes, and chronic kidney disease. An orally-available antioxidant inflammation modulator.
Targets/IC50/Ki
IKK
(Cell-free assay)
Ferroptosis
Nrf2
NF-κB
In vitro

Bardoxolone Methyl exhibits potent inhibitory activities against production of nitric oxide induced by interferon-Ƴ in mouse macrophages with IC50 of 0.1 nM. This compound decreases the viability of leukemic HL-60, KG-1, and NB4 cells with IC50 of 0.4, 0.4, and 0.27 μM, respectively. It induces pro-apoptotic Bax protein, inhibits the activation of ERK1/2, and it blocks Bcl-2 phosphorylation, which contributes to the induction of apoptosis. This chemical potently inhibits both constitutive and inducible NF-kappaB activated by TNF, interleukin (IL)-1beta, phorbol ester, okadaic acid, hydrogen peroxide, lipopolysaccharide, and cigarette smoke.

Kinasanalys
IKK-analys
För att bestämma effekten av CDDO-Me på TNF-inducerad IKK-aktivering analyseras IKK. Kortfattat fälls IKK-komplexet från helcellsextrakt ut med antikropp mot IKKα och IKKβ och behandlas sedan med protein A/G-Sepharose-kulor. Efter 2 timmar tvättas kulorna med lyseringsbuffert och resuspenderas sedan i en kinasanalysblandning innehållande 50 mmol/L HEPES (pH 7,4), 20 mmol/L MgCl2, 2 mmol/L DTT, 20 μCi [γ-32P]ATP, 10 μmol/L omärkt ATP och 2 μg av substratet glutation S-transferas-IκBα (aminosyror 1-54). Efter inkubation vid 30°C i 30 minuter avbryts reaktionen genom kokning med SDS-provbuffert i 5 minuter. Slutligen separeras proteinet på 10% SDS-PAGE, gelen torkas och de radioaktiva banden visualiseras med en Storm820. För att bestämma de totala mängderna IKK-α och IKK-β i varje prov separeras 50 μg helcellsproteiner på 7,5% SDS-PAGE, elektroöverförs till ett nitrocellulosamembran och blottas sedan med antingen anti-IKK-α- eller anti-IKK-β-antikropp.
In vivo

Bardoxolone Methyl (60 mg/kg) reduces the number, size, and severity of lung tumors in vivo. This compound 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.
