Biological Activity

Description Tert-butylhydroquinone (TBHQ) is an antioxidant compound which is used to prevent lipid peroxidation and shows multiple cytoprotective actions. It is an activator of Nrf2.
Targets
Nrf2 [1]
In vitro Tert-butylhydroquinone (tBHQ) is a metabolite of the chemical compound butylated hydroxyanisole and induces Nrf2 activation and conveys protection against hydrogen peroxide, 6-hydroxydopamine, the pesticidal deltamethrin, and other toxicants. tBHQ preferentially alters the redox status in the mitochondrial compartment in HeLa cells. HeLa cells treated with tBHQ show a preferential oxidation of mitochondrial thioredoxin-2 (Trx2), while cellular glutathione and cytosolic thioredoxin-1 are not affected[1]. In cultured H9c2 cells and primary cardiac myocytes, TBHQ stimulates Akt phosphorylation and suppresses oxidant-induced apoptosis[2].
In vivo TBHQ treatment elicits significant cytoprotective actions in different organs under pathological conditions. Systemic or local intra-cerebroventricular treatment with TBHQ in an ischemic stroke model in rats significantly reduces the infarct size and neurological deficits. Administration of TBHQ in rats suppresses renal damage and oxidative stress after ischemia and reperfusion injury. In mice with type 1 diabetes, chronic treatment with TBHQ significantly reduces the degree of glomerular fibrosis and ameliorates proteinuria. TBHQ treatment prevents left ventricular dilatation and cardiac dysfunction induced by transverse aortic constriction (TAC), and decreases the prevalence of myocardial apoptosis. The beneficial effects of TBHQ are associated with an increase in Akt activation, but not related to activations of Nrf2 or AMP-activated protein kinase. TBHQ-induced Akt activation is accompanied by increased phosphorylation of Bad, glycogen synthase kinase-3β (GSK-3β) and mammalian target of rapamycin (mTOR)[2].

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    HeLa cells

  • Concentrations

    0-15 μM

  • Incubation Time

    1 h

  • Method

    HeLa cells are grown until confluent and loaded with 100 µM DCF in loading medium (DMEM with 1% FBS) for 30 min. Cells are washed and then treated with tBHQ (0-15 μM in DMSO) for 1 h. DCF fluorescence is followed in a fluorometer at 488-nm excitation and 520-nm emission.
Animal Study:

[2]
  • Animal Models

    male C57BL/6 mice

  • Dosages

    ratio of 1% (w/w) with the animal food powder

  • Administration

    oral
