生物活性

Bardoxolone methyl (NSC 713200; RTA 402; CDDO Methyl ester) is a synthetic triterpenoid compound with potential antineoplastic and anti-inflammatory activities, acting as an activator of the Nrf2 pathway and an inhibitor of the NF-κB pathway.

IC50 & Target

Nrf2[1]
体内研究
(In Vivo)

Bardoxolone methyl (30 mg/kg, p.o.) decreases renal expression of megalin but not cubilin, increases creatinine clearance and urinary albumin-to-creatinine ratios, and induces Nrf2 cytoprotective targets in cynomolgus monkeys[1]. Bardoxolone methyl induces overall favorable effects on the heart via its improvement in eGFR in both animal models and clinical trials[2].

Animal Administration
[1]

Two separate in-life studies are conducted in cynomolgus monkeys. In one study, cynomolgus monkeys (n=9/gender/dose group) are administered amorphous bardoxolone methyl by oral gavage, using sesame oil as the vehicle, at 5, 30, and 300 mg/kg once daily for 12 months in a GLP environment. Observations for morbidity, mortality, injury, and the availability of food and water are conducted twice daily for all animals. Clinical observations and body weights are conducted and recorded weekly. Weight data are analyzed by calculating the area under the weight versus time curve using the linear trapezoidal method. Blood samples for clinical chemistry evaluations are collected from all animals pretest and from all animals prior to interim (6-month) and terminal (12-month) necropsies. An additional group of monkeys for each dose group are allowed to recover for 4 weeks.

生物活性

Omaveloxolone (RTA 408) is an antioxidant inflammation modulator (AIM), which activates Nrf2 and suppresses nitric oxide (NO). Omaveloxolone attenuates osteoclastogenesis by inhibiting STING dependent NF-κb signaling.

IC50 & Target

Nrf2[1]
体外研究
(In Vitro)

To evaluate the anti-inflammatory activity of Omaveloxolone (RTA 408), RAW 264.7 mouse macrophage cells are treated with Omaveloxolone for two hours and then IFNγ is added to stimulate NO production and release into the media. Omaveloxolone dose-dependently reduces NO concentrations in the media with an IC50 value of 4.4±1.8 nM. The potency of Omaveloxolone in this assay is similar to that of Bardoxolone methyl, which has an IC50 value of 1.9±0.8 nM. Nrf2 activation is required for AIM-mediated NO suppression. A decrease in nitric oxide synthase 2 (Nos2) protein levels is observed in bardoxolone methyl-treated RAW 264.7 cells, which is attenuated when Nrf2 mRNA levels are reduced by siRNA. To evaluate the anticancer activity of Omaveloxolone, a panel of eight human cell lines derived from tumors of different origin are treated with Omaveloxolone and measured cell growth 72 hours later using the sulforhodamine B (SRB) assay. Omaveloxolone inhibits the growth of all tumor lines with an average GI50 value of 260±74 nM. To determine whether Omaveloxolone induces apoptosis, the panel of tumor cells are treated with Omaveloxolone and the caspase substrate, DEVD-AFC, for 24 hours. Omaveloxolone dose-dependently increases DEVD-AFC cleavage, indicating that Omaveloxolone treatment triggers caspase activation in cancer cells. Caspase-3 and caspase-9 cleavage is also observed by western blot at the same concentrations of Omaveloxolone that increases DEVD-AFC cleavage[1].

体内研究
(In Vivo)

To determine whether Omaveloxolone (RTA-408) is an effective mitigator of hematopoietic acute radiation syndrome after bone marrow-lethal doses of total-body irradiation (TBI), mice are administered 3 daily injections of 17.5 mg/kg Omaveloxolone beginning 24 h after TBI. Teatment with Omaveloxolone results in the 35 day survival of 100% of 7 Gy (LD40/35) TBI mice (P<0.05) and 60% of 7.5 Gy (LD100/13) TBI mice (P<0.0001)[2].

Cell Assay
[1]

MEFs, PANC-1, A549, A375, A549/NF-κB-Luc and HeLa/NF-κB-Luc cells are cultured in Gibco high glucose DMEM with 10% FBS. G-361 cells are cultured in McCoy’s 5A medium with 10% FBS. All other cell lines are cultured in RPMI 1640 medium with 10% FBS. For growth inhibition assays, cells are plated in duplicate 96-well culture dishes at 3×103 cells per well. The following day, one plate is treated with Omaveloxolone (200, 400, 600, 800 and 1000 nM) and the other is immediately processed for the sulforhodamine B (SRB) assay (time 0). Cells in the Omaveloxolone-treated plate are processed for the SRB assay 72 hours after the start of treatment. Percentage of growth relative to vehicle-treated cells is calculated. Dose-response curves are plotted in GraphPad Prism and GI50 values are calculated. For cell counting experiments, MEFs are plated in 6-well culture dishes at 5×104 cells per well and treated with Omaveloxolone the following day. Following treatment, cells are counted using a Vi-CELL XR cell analyzer. For clonogenic assays, wild-type (1×103 cells per well) and Keap1-/- (0.5×103 cells per well) MEFs are seeded in 6-well dishes. Six hours later, MEFs are treated with Omaveloxolone. After seven days, colonies are fixed with a 1:7 solution of acetic acid:MeOH and stained with 0.5% crystal violet in MeOH. Colonies consisting of ≥50 cells are counted[1].

Mice[2]
For radiation survival experiments, wild-type C57Bl/6 CD45.2 mice (6-8 weeks old) are used. Congenic wild-type C57Bl/6 CD45.1 and C57Bl/6 CD45.1/CD45.2 hybrid host mice are used as recipients in transplantation experiments. Omaveloxolone stock solutions for vehicle control (DMSO) are prepared within 1 h before injection. Omaveloxolone (17.5 mg/kg) or DMSO is administered intraperitoneally at 24, 48 and 72 h after irradiation. Whole-body irradiation (7-8 Gy) is performed using a 250-kVp X-ray machine with 50 cm source-to-skin distance and a 2 mm copper filter. The dose rate is approximately 1.4 Gy/min.

体外研究
(In Vitro)

CDDO-Im is highly active in suppressing cellular proliferation of human leukemia and breast cancer cell lines (IC50 approximately 10-30 nM). In U937 leukemia cells, CDDO-Im also induces monocytic differentiation as measured by increased cell surface expression of CD11b and CD36[1]. Treatment with CDDO-Im elevates protein levels of Nrf2, a transcription factor previously shown to bind ARE sequences, and increases expression of a number of antioxidant and detoxification genes regulated by Nrf2[2]. CDDO-Im is one of the most potent synthetic triterpenoids shown to induce growth inhibition and apoptosis in various human cancer cells, including multiple myeloma, lung, pancreas and breast cancer. CDDO-Im treatment markedly induces cell cycle arrest at G2/M-phase and apoptosis in the triple-negative breast cancer cell lines, SUM159 and MDA-MB-231. The CD24−/EpCAM+ cells in SUM159 tumorspheres are significantly inhibited by CDDO-Im treatment. CDDO-Im also significantly decreases sphere forming efficiency and tumorsphere size in both primary and secondary sphere cultures[3].

体内研究
(In Vivo)

CDDO-Im is a potent inhibitor of de novo inducible nitric oxide synthase expression in primary mouse macrophages. Moreover, CDDO-Im inhibits growth of B16 murine melanoma and L1210 murine leukemia cells in vivo. Injection of 10 nM (5.4 μg) of CDDO-Im almost completely blocks the ability of IFN-γ to induce iNOS, and treatment with as little as 1 nmol of CDDO-Im (0.54 μg) is partially effective[1].

Mice: Mice are injected i.p. with thioglycollate, and the resulting resident peritoneal macrophages are activated 3 days later with an i.p. injection of IFN-γ. CDDO and CDDO-Im are injected i.p. 30 min after IFN-γ. Macrophages are harvested 10 h later, cultured for 12 h, and then assayed for expression of iNOS protein and production of nitric oxide (NO)[1].
