Bardoxolone methyl 生物活性

描述 The NF-kB pathway plays a key role in multiple cellular processes, including immune signaling, inflammation, development, proliferation and survival. NF-κB suppression occurred through inhibition, activation, phosphorylation and degradation of IκB-α, p65 phosphorylation, p65 nuclear translocation, and NF-κB-mediated reporter gene transcription. Bardoxolone Methyl is a synthetic triterpenoid based on naturally occurring ursolic and oleanolic acids and can inhibit both constitutive and inducible NF-κB through inhibition of IκB-α kinase. Pre-treatment with 1μM Bardoxolone Methyl for 8h could inhibit TNF-induced IκB-α activation, IκB-α phosphorylation within 30 minutes, and subsequently p65 phosphorylation and p65 nuclear translocation in KBM-5cells, without direct effect on IKK. Consistent with this, as the expression of COX-2, MMP-9 and VEGF is regulated by NF-κB, 1μM Bardoxolone Methyl could inhibit TNF-induced expression of this three proteins in a time-dependent manner in KBM-5 cells pre-treated with Bardoxolone Methyl for 8h. Bardoxolone Methyl could enhance the apoptosis induced by TNF or chemotherapeutic agents, including Taxol, 5-fluorouracil and doxorubicin, through inhibition of NF-κB activation in KBM-5 cells. Oral administration of 10 mg/kg Bardoxolone Methyl for 21 weeks could prevent the colon inflammation induced by high fat diet in mice through its effect on regulation of macrophages, NF-κB, cytokines, Cox2 and Ki67, fat deposition and microflora.
体内研究

Bardoxolone methyl (30 mg/kg, oral administration) reduces renal megalin expression while maintaining cubilin levels, enhances creatinine clearance, reduces urinary albumin-to-creatinine ratios, and activates Nrf2 cytoprotective pathways in cynomolgus monkeys[1].

Bardoxolone methyl elicits beneficial cardiac effects by enhancing estimated glomerular filtration rate (eGFR) in both preclinical studies and clinical trials[2].
