产品描述 | Bardoxolone (CDDO) is a synthetic oleanane triterpenoid that blocks the cellular synthesis of inducible nitric oxide synthase and inducible COX-2 in INF-γ-activated mouse macrophages with an IC50 value of 0.4 nM. By suppressing reactive oxygen and nitrogen species (ROS/RNS) formation, it promotes the cellular control of ROS/RNS levels that would lead to DNA damage associated with tumorigenesis. In various Y cell lines, Bardoxolone has been shown to specifically inhibit proliferation and induce apoptosis. Mechanism studies revealed that Bardoxolone is a ligand for peroxisome proliferator-activated receptor γ, and also that it induces genes regulated by Nrf2, including heme oxygenase-1 and eotaxin-1, which play a role in antioxidant response element signaling activity. |
体外活性 | Bardoxolone methyl是一种新型合成三萜类和抗氧化炎症调节剂,能强效诱导Nrf2并抑制NF-κB与Janus激活的激酶/STAT信号传导。研究表明,Bardoxolone methyl能够诱导癌细胞系的分化、抑制增殖及诱导凋亡[2]。 |
体内活性 | 经巴Bardoxolone methyl 处理的猴肾切片显示,尽管各组间mRNA表达相似,但megalin蛋白表达降低。通过密度测量分析确认,megalin蛋白表达的可视化降低,显示Bardoxolone methyl显著降低了猴肾中的megalin蛋白表达。Bardoxolone methyl的给药不影响肾中cubilin的蛋白表达或cubilin的mRNA表达。与基线相比以及在28天内给予载体的动物中,接受Bardoxolone methyl治疗的猴子的肌酐清除率显著不同。经过28天的Bardoxolone methyl给药后,从24小时尿液收集中确定的尿白蛋白/肌酐比率(UACRs)与接受载体的动物相比显著增加。值得注意的是,接受载体治疗的动物UACRs下降了53.3%,而接受Bardoxolone methyl治疗的猴子增加了27.9%。雄性C57BL/6J小鼠,在高脂饮食(HFD)喂养期间口服BARD(HFD/BARD),或仅喂食高脂饮食(HFD),或喂食低脂饮食(LFD)21周。与LFD小鼠相比,HFD小鼠的F4/80冠状结构数量显著增加(+95%;p<0.001),而BARD有效预防了这一增加(-50%;p<0.01)。同样,与LFD小鼠相比,HFD小鼠的F4/80间质巨噬细胞数量显著增加98%(p<0.001),而与HFD/BARD小鼠相比增加32%(p<0.01)。 |
