In vitro

Bardoxolone Methyl vertoont krachtige remmende activiteiten tegen de productie van stikstofmonoxide geïnduceerd door interferon-Ƴ in muismacrofagen met een IC50 van 0,1 nM. Deze verbinding vermindert de levensvatbaarheid van leukemische HL-60, KG-1 en NB4 cellen met een IC50 van respectievelijk 0,4, 0,4 en 0,27 μM. Het induceert pro-apoptotisch Bax-eiwit, remt de activering van ERK1/2 en blokkeert Bcl-2-fosforylering, wat bijdraagt aan de inductie van apoptose. Deze chemische stof remt potent zowel constitutief als induceerbaar NF-kappaB geactiveerd door TNF, interleukine (IL)-1beta, phorbolester, okadaic acid, waterstofperoxide, lipopolysaccharide en sigarettenrook.

Kinase Assay
IKK-test
Om het effect van CDDO-Me op TNF-geïnduceerde IKK-activering te bepalen, wordt IKK geanalyseerd. Kortom, het IKK-complex uit hele-cel-extracten werd geprecipiteerd met antilichaam tegen IKKα en IKKβ en vervolgens behandeld met proteïne A/G-Sepharose-bolletjes. Na 2 uur worden de bolletjes gewassen met lysisbuffer en vervolgens geresuspendeerd in een kinase-assaymengsel dat 50 mmol/L HEPES (pH 7,4), 20 mmol/L MgCl2, 2 mmol/L DTT, 20 μCi [γ-32P]ATP, 10 μmol/L ongelabeld ATP en 2 μg substraat glutathion S-transferase-IκBα (aminozuren 1-54) bevat. Na incubatie bij 30°C gedurende 30 minuten wordt de reactie beëindigd door 5 minuten te koken met SDS-samplebuffer. Tenslotte wordt het eiwit opgelost op 10% SDS-PAGE, de gel gedroogd en de radioactieve banden gevisualiseerd met een Storm820. Om de totale hoeveelheden IKK-α en IKK-β in elk monster te bepalen, wordt 50 μg hele-cel-eiwitten opgelost op 7,5% SDS-PAGE, elektro-overgebracht naar een nitrocellulosemembraan en vervolgens geblot met ofwel anti-IKK-α of anti-IKK-β antilichaam.
In vivo

Bardoxolone Methyl (60 mg/kg) vermindert het aantal, de grootte en de ernst van longtumoren in vivo. Deze verbinding vermindert significant de in vivo inflammatoire cytokinerespons na LPS-challenge, induceert HO-1-eiwitexpressie in de milt en beschermt muizen tegen een letale dosis LPS.
