説明
2,6-DimethoXY-1A-benzoquinone is an allergen in
more than 50 different plants and wood species, e.g.,
mahogany, macore~, sipo, wenge, oak, beech, elms, and
poplar. With acamelin, it is one of the allergens of
Acacia melanoxylon. Sensitization can occur in woodworkers
such as carpenters, joiners and sawyers.
化学的特性

使用
2,6-Dimethoxy-1,4-benzoquinone may be used in the synthesis of 2-aryl-3,5-dimethoxy-1,4-benzoquinone derivatives.
一般的な説明
2,6-Dimethoxy-1,4-benzoquinone (DBQ, 2,6-DMBQ, DMOBQ) is a 1,4-benzoquinone derivative. It is a wood allergen, has been reported to cause various skin and mucosal symptoms on exposure to wood dusts. It is formed as a product due to the activity of bacterial
Azospirillum lipoferum laccase on phenolic compounds of the syringic type. DBQ is one of the components isolated from the rhizome of
Gynura japonica with a potential to show anti-platelet aggregation activity
in vitro. It is an anticancer agent, whose kinetics of cyclic redox transformation induced by ascorbate (AscH-) has been studied using the Clark electrode and ESR techniques. Its electrochemical reduction in acetonitrile has been studied.
