Drug metabolism and disposition: the biological fate of chemicals, 20(6), 816-820 (1992-11-01)
3-Tert-butyl-4-hydroxyanisole (3-BHA) was metabolized in the presence of horseradish peroxidase and hydrogen peroxide to 2-tert-butyl-p-benzoquinone (TBQ), 2,3-epoxy-5-tert-butyl-1,4-benzoquinone (TBQ-epoxide), and two known dimers. The formation of TBQ from 3-BHA required both horseradish peroxidase and hydrogen peroxide. When 2.5 mM 3-BHA was

Mutation research, 241(2), 125-132 (1990-06-01)
The mutagenicity of 3-tert-butyl-4-hydroxyanisole (BHA) and its metabolites was investigated in the reverse mutation assay using S. typhimurium strains and the chromosomal aberration test in vitro using a Chinese hamster fibroblast cell line, CHL. BHA, tert-butylhydroquinone (BHQ), tert-butylquinone (BQ) and
Muhammad Zia-ur-Rehman et al.
European journal of medicinal chemistry, 44(3), 1311-1316 (2008-09-23)
A novel series of potentially biologically active 4-hydroxy-N'-(benzylidene)-2H-benzo[e][1,2]thiazine-3-carbohydrazide 1,1-dioxides were synthesized starting from ultrasonic mediated N-alkylation of sodium saccharin with methyl chloroacetate. Ring expansion of methyl(1,1-dioxido-3-oxo-1,2-benzisothiazol-2(3H)-yl)acetate followed by its hydrazinolysis afforded 4-hydroxy-2H-1,2-benzothiazine-3-carbohydrazide 1,1-dioxide which was reacted in a straight forward
M Hirose et al.
Toxicology, 43(2), 139-147 (1987-02-01)
The mechanism of the carcinogenic or toxic action of BHA on rat forestomach was examined by studies on the excretion and tissue distribution of radioactivity in F344 male rats given tert-butyl- or methoxy-labelled 3-BHA orally. Within 2 days after a
K Morimoto et al.
Carcinogenesis, 12(4), 703-708 (1991-04-01)
DNA damage in the forestomach epithelium of male F344 rats was tested by alkaline elution assay following oral administration of 3-tert-butyl-4-hydroxyanisole (3-BHA) and its free metabolites. Although 1% 3-BHA and 0.001% tert-butylhydroquinone (BHQ) caused no detectable DNA damage, a tert-butylquinone
