    Description

    TBHQ (tert-Butylhydroquinone) is a widely used Nrf2 activator, protects against Doxorubicin (DOX)-induced cardiotoxicity through activation of Nrf2[1]. TBHQ (tert-Butylhydroquinone) is also an ERK activator; rescues Dehydrocorydaline (DHC)-induced cell proliferation inhibitionin melanoma[2].

    In Vitro

    TBHQ (t-butylhydroquinone; tBHQ; 0-100 μM; 48 hours; H9c2 cells) alone does not affect H9c2 cells viability. Pre-incubation of the H9c2 cells with various concentrations of tBHQ for 24 hours enhances cell viability which is decreased due to exposure to ethanol in a dose-dependent manner. Treatment with tBHQ markedly enhances the viability of H9c2 cardiomyocytes exposed to ethanol[3].
    TBHQ (5 μM; 15 min; H9c2 cells) treatment significantly reduces the amount of apoptotic cells exposed to ethanol[3].
    TBHQ (5 μM; H9c2 cells) pre-treatment markedly inhibites the ethanol-induced increase in caspase-3 and Bax expression, and enhances Bcl-2 expression[3].

    In Vivo

    TBHQ treatment (50 mg/kg; Intraperitoneal injection; three injections at intervals of 8 h that began 1-h post ICH; CD-1 mice) augments the DNA-Binding activity of Nrf2, attenuates oxidative brain damage and acute neurological deficits afterintracerebral hemorrhage (ICH), attenuates microglial activation with concomitant reduction in the release of proinflammatory cytokine interleukin-1β (IL-1β). TBHQ has the efficacy of post-injury administration in attenuating acute neurological injury after ICH[4].

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.5 mg/mL (15.04 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: ≥ 2.5 mg/mL (15.04 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.

    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.
