2,6- di- tert- butyl- 4- methylene- 2,5- cyclohexadienone

08/01/1996 - "Indeed, 4-CD3-BHTOOH, an analogue that generates less of the metabolite BHT-quinone methide (2,6-di-tert-butyl-4-methylene-2,5-cyclohexadienone) and fewer tumors in vivo, accordingly exhibited diminished potency for activating ERK. "
05/01/1994 - "Taken together, these results provide insight into the cellular mechanisms through which the reactive electrophile BHT-quinone methide can mediate alterations in gene expression, such as occur in tumor promotion in vivo."
09/01/1993 - "BHT-QM has also been demonstrated to mediate tumor promotion in mouse skin by another metabolite of BHT, 2,6-di-tert-butyl-4-hydroperoxy-4-methyl-2,5-cyclohexadienone (BHTOOH). "
10/01/2005 - "Two quinone methide (QM) metabolites of the phenolic antioxidant butylated hydroxytoluene (BHT), 2,6-di-tert-butyl-4-methylenecyclohexa-2,5-dienone (BHT-QM) and the tert-butyl-hydroxylated derivative (BHTOH-QM), are believed to be responsible for promoting lung tumor formation in mice treated with BHT. "
12/01/2004 - "The present work was undertaken to determine if glutathione S-transferase P1-1 (GSTP1-1) is alkylated by BHT-QM, as this protein is overexpressed in tumors and has important roles in protecting cells from electrophiles and oxidants and in regulating stress kinases. "

03/01/2006 - "Proliferation of murine lung epithelial-12 cells in vitro after 8 h of treatment with BHT quinone-methide and hyperoxia and 48 h of normoxic recovery was enhanced 2.7-fold compared with vehicle-treated control mice at the same time point. "

03/01/1987 - "Male Sprague-Dawley rats were given butylated hydroxytoluene (BHT) in a dose of 800 mg/kg body weight orally, and 0.5-72 hr later plasma concentrations of factors II, VII, IX and X and hepatic levels of BHT and BHT quinone methide (2,6-di-tert-butyl-4-methylene-2,5-cyclohexadienone) were determined.
