Discovery of nitrogenous derivatives of dihydromyricetin in cell culture medium
Dihydromyricetin (DMY) is a health‐beneficial flavanonol in the family of flavonoids, extracted from Ampelopsis grossedentata (Hand.‐Mazz.) W. Wang. When investigating the stability of DMY in Dulbecco's modified Eagle's medium (DMEM) solution at 37°C by ...

Microsomal superoxide anion production and NADPH-oxidation in a series of 22 aziridinylbenzoquinones [PDF]
Several 2,5-bis(1-aziridinyl)-1,4-benzoquinones (BABQs) can be activated to alkylating species by reduction of the quinone moiety. On the other hand, cytotoxicity of these compounds can be induced by redox cycling.

Generation of superoxide and singlet oxygen from α-tocopherolquinone and analogues. [PDF]
Three potential routes to generation of reactive oxygen species from a tocopherolquinone have been identified. The quinone of the water-soluble vitamin E analogue Trolox C (Trol-Q) is reduced by hydrated electron and isopropanol a hydroxyalkyl radical ...

A novel quinone: Quinone methide isomerase generates quinone methides in insect cuticle
Insoluble cuticle‐bound enzyme(s) of Manduca sexta pharate pupae, which is known to convert N‐acetyldopamine to N‐acetylnorepinephrine through the intermediate formation of quinone methide, also converted exogenously supplied N‐acetyldopamine quinone to N‐acetylnorepinephrine.
