Descrição geral

2-tert-Butyl-1,4-benzoquinone (TBQ, TBBQ, tBQ, BuBQ, BQ , tert-butyl-p-quinone) is a 1,4-benzoquinone derivative. It is a major metabolite of the food additive, butylated hydroxyanisole (BHA). TBQ is reported to be strongly cytotoxic in human monocytic leukemia U937 cells. TBQ is an oxidation product of 2-tert-butylhydroquinone (TBHQ). Studies confirm that TBQ induces apoptosis and cell proliferation inhibition in chronic myelogenous leukemia (CML) cells. Its binding interactions with lysozyme has been examined and found to be intermediate between BHA and TBHQ. It has been reported to be synthesized by the titanium superoxide catalyzed oxidation of 2-tert-butylphenol using aq. 30% H2O2. TBQ is one of the main neoformed compounds from TBHQ decomposition in PLA-TBHQ film (Poly lactic acid).

Aplicação

2-tert-Butyl-1,4-benzoquinone may be used in the synthesis of azatrioxa[8]circulene.

The synthetic antioxidant butylated hydroxyanisole (BHA) stimulates superoxide formation in rat liver microsomes up to 10-fold. This stimulation is prevented by the monooxygenase inhibitor metyrapone and does not occur when NADH is consumed instead of NADPH indicating that metabolic activation

We examined t-butylhydroquinone (t-BHQ) and t-butylquinone (t-BuQ), two of the major microsomal metabolites of the synthetic antioxidant butylated hydroxyanisole (BHA), for their ability to react with the xenobiotic arylamines aniline and N-methylaniline.

The food additive butylated hydroxyanisole (BHA) has been shown to induce gastrointestinal hyperplasia in rodents by an unknown mechanism. The relevance of this observation for human risk assessment is not clear. We therefore analysed the effect of BHA and its
