Microsomal superoxide anion production and NADPH-oxidation in a series of 22 aziridinylbenzoquinones [PDF]
, 1989 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.

The Candida albicans ζ-crystallin homolog Zta1 promotes resistance to oxidative stress
mSphere, 2023 The fungal pathogen Candida albicans is capable of causing lethal infections in humans. Its pathogenic potential is due in part to the ability to resist various stress conditions in the host, including oxidative stress.

Characterization of a Reductively-Activated Elimination Pathway Relevant to the Biological Chemistry of the Kinamycins and Lomaiviticins [PDF]
, 2012 The lomaiviticins (1 and 2) and kinamycins (3–5) are bacterial metabolites with potent antimicrobial and antiproliferative activities. Herein we establish that 1–5 are capable of generating electrophilic acylfulvene intermediates (6) under mildly ...

A novel quinone: Quinone methide isomerase generates quinone methides in insect cuticle
FEBS Letters, 1988 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.

Electrochemistry of potentially bioreductive alkylating quinones : Part 1. Electrochemical properties of relatively simple quinones, as model compounds of mitomycin- and aziridinylquinone-type antitumour agents [PDF]
, 1990 The influence of methyl-, hydroxy and amino substituents on the electrochemical behaviour of simple 1,4-naphtho-and 1,4-benzoquinones, model compounds of many quinoid antitumour agents, in aqueous media was studied. Significant changes in electrochemical
