Customer Review

    Brusatol purchased from MCE. Usage Cited in: Invest Ophthalmol Vis Sci. 2020 Jun 3;61(6):51.  [Abstract]

    After pretreatment HCECs with 20 nM Brusatol (BT) for 2 hours, add 0.6 mM PAE or DMSO for 4 hours, and then stimulated with A. fumigatus for 8 hours or 24 hours. The Nrf2 and HO-1 expression declined in normal HCECs pretreated with Brusatol (BT). BT partially inhibits PAE-induced Nrf2 and HO-1 expression in infected HCECs.

    Brusatol purchased from MCE. Usage Cited in: Invest Ophthalmol Vis Sci. 2020 Jun 3;61(6):51.  [Abstract]

    PCR and ELISA results show the mRNA and protein levels of IL-6, IL-8, and TNF-α after blocking Nrf2 activity. Brusatol (BT) pretreatment partially reverses IL-6, TNF-α, and IL-8 expression levels, which are inhibited by PAE in infected HCECs.

    生物活性

    Brusatol (NSC 172924) is a unique inhibitor of the Nrf2 pathway that sensitizes a broad spectrum of cancer cells to Cisplatin and other chemotherapeutic agents. Brusatol enhances the efficacy of chemotherapy by inhibiting the Nrf2-mediated defense mechanism. Brusatol can be developed into an adjuvant chemotherapeutic agent[1]. Brusatol increases cellular apoptosis[2].

    IC50 & Target

    Nrf2[1]

    体外研究
    (In Vitro)

    Brusatol (0.05, 0.15, 0.45, 1.35, 4.05 and 12.15 μg/mL) reduces the viability of CT-26 cells in a dose-dependent manner with IC50 value of 0.27±0.01μg/mL. When Brusatol is combined with Cisplatin (CDDP) at a constant concentration ratio of 1:1, cell growth inhibition is markedly enhanced compared with single-agent treatment; the IC50 value of Brusatol and CDDP cotreatment is 0.19±0.02μg/mL[2].
    Brusatol provokes a rapid and transient depletion of Nrf2 protein, through a posttranscriptional mechanism, in mouse Hepa-1c1c7 hepatoma cells. Brusatol sensitizes mammalian cells to chemical toxicity[3].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Cell Viability Assay[2]

    Cell Line: The murine CT-26 CRC cell line
    Concentration: 0.05, 0.15, 0.45, 1.35, 4.05 and 12.15 μg/mL
    Incubation Time: 48 hours
    Result: The viability of CT-26 cells was reduced in a dose-dependent manner, with IC50 value of 0.27±0.01 μg/mL.

    Western Blot Analysis[3]

    Cell Line: Mouse Hepa-1c1c7 hepatoma cells
    Concentration: 1, 3, 10, 30, 100, 300, and 1000 nM
    Incubation Time: 2 hours
    Result: Provoked the depletion of Nrf2, in a concentration-dependent manner within 2 h of exposure to cells.
    体内研究
    (In Vivo)

    Brusatol is able to reach the tumor tissue and inhibit the Nrf2 pathway. Nude mice are injected with A549 cells to induce tumor growth, followed by a single i.p. injection of 2 mg/kg Brusatol. Nrf2 protein levels are significantly decreased at 24 h or 48 h postinjection[1].
    Cisplatin (2 mg/kg) or Brusatol (2 mg/kg) alone does not inhibit tumor growth significantly, whereas in the combination group, tumor size is significantly reduced[1]. "

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Model: Athymic nude mice 4-6 wk old bearing A549 xenografts[1]
    Dosage: 2 mg/kg
    Administration: Treated i.p.; Cisplatin (2 mg/kg), Brusatol (2 mg/kg), or in combination every other day for a total of five times
    Result: Nrf2 protein levels were significantly decreased at 24 h or 48 h postinjection.
    Cisplatin or Brusatol alone did not inhibit tumor growth significantly, whereas in the combination group, tumor size was significantly reduced. "

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
