20219682 Liu B, Xie J, Ge X, Xu P, Wang A, He Y, Zhou Q, Pan L, Chen R: Effects of anthraquinone extract from Rheum officinale Bail on the growth performance and physiological responses of Macrobrachium rosenbergii under high temperature stress. Fish Shellfish Immunol. 2010 Feb 26.

After high temperature stress, 0.1-0.2% anthraquinone extract also could improve the haemolymph total proteins, lysozyme and ALP activities, hepatic catalase, and superoxide dismutase, and reduce haemolymph ALT and AST activities, hepatic malondialdehyde contents.

7618176 Leskovac V, Trivic S, Peggins JO: Primary toxic effects of anthraquinone-2-sulfonic acid in rat liver microsomes. Toxicol Lett. 1995 Jul;78(2):107-10.

(1) The endogenous, NADPH-supported production of H2O2 and of O2-.-radicals in rat liver microsomes was very strongly enhanced in the presence of anthraquinone-2-sulfonic acid (AQSA). (2) This induction of H2O2 and of O2-.-radicals was catalyzed by the microsomal NADPH:cytochrome P450 oxidoreductase (EC 1.6.2.4). (3) AQSA was reduced to AQSA radicals by reductase; AQSA radicals reduce molecular oxygen to O2-.-radicals, which are readily dismutated to H2O2 by the microsomal superoxide dismutase. (4) O2-.-radicals are the sole precursors of all AQSA-induced production of H2O2 in liver microsomes.

Anthraquinone-2-sulfonate was the better electron acceptor, and maximal rates of 943 micromoles per hour per milligram chlorophyll for O (2) uptake were observed for Phormidium laminosum preparations in the presence of superoxide dismutase.

3094197 Wallace KB: Nonenzymatic oxygen activation and stimulation of lipid peroxidation by doxorubicin-copper. Toxicol Appl Pharmacol. 1986 Oct;86(1):69-79.

Associated with these changes was a copper-dependent consumption of dissolved oxygen and a superoxide dismutase-sensitive reduction of ferricytochrome c, suggesting the liberation of superoxide free radicals.
The suggested occurrence of doxorubicin-copper complexes in vivo infers that nonenzymatic generation of oxygen-free radicals by the chelate may contribute to the mechanism of toxicity of doxorubicin and related anthraquinone anticancer agents observed clinically.

Emodin, 1,3,8-trihydroxy-6-methyl-anthraquinone, is an anthraquinone derivative from the roots of Rheum officinale Baill that has been used to treat many diseases in digestive system for thousands of years.
At 24 h, 48 h and 72 h time points after administration, liver function, pathological changes of hepatic tissue, tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, myeloperoxidase (MPO), malondialdehyde (MDA), superoxide dismutase (SOD), cytokine-induced neutrophil chemoattractant (CINC)-1, macrophage inflammatory protein (MIP)-2, intercellular adhesion molecule (ICAM)-1, nuclear factor (NF)-kappaB and early growth response (Egr)-1, nitric oxide (NO) and inducible nitric oxide synthase (iNOS) were detected.

The structure-activity relationship of emodin and 10 other anthraquione derivatives indicates that the free hydroxyl group at the beta-position of the anthraquinone nucleus plays an important role in the immunosuppressive effect.
The suppressive activity of emodin was significantly inhibited by catalase (a scavenger of hydrogen peroxide), but little affected by superoxide dismutase (a scavenger of superoxide radical) and mannitol (a scavenger of hydroxyl radical).

Ferritin iron was released by a number of bipyridyl radicals including those derived from diquat and paraquat, the anthracycline radicals of adriamycin, daunorubicin and epirubicin, the semiquinones of anthraquinone-2-sulphonate, 1,5 and 2,6-dihydroxyanthraquinone, 1-hydroxyanthraquinone, purpurin, and plumbagin, and the nitroaromatic radicals of nitrofurantoin and metronidazole.
In air, iron release was inhibited by superoxide dismutase.

Our previous study had found that aloe-emodin sulfates/glucuronides metabolites, an anthraquinone polyphenol, exerted a neuroprotective activity upon RGCs.

Rubroskyrin, a modified bis-anthraquinone pigment from Penicillium islandicum Sopp, was studied on the redox interaction with NADH-linked redox system of rat liver microsomes, comparing with luteoskyrin and rugulosin.
The H2O2 production was significantly accelerated by superoxide dismutase (SOD), suggesting the production of superoxide anion during the reduction-autoxidation cycles of rubroskyrin.

This reduction was prevented by superoxide dismutase (SOD) indicating O (-) (2) generation.
The probable source of O (-) (2) in the D. coccus hemolymph is the anthraquinone oxidation, since commercial carminic dye produced O (-) (2) during its oxidation by Agaricus bisporus tyrosinase.

This paper examines the photochemical properties of two Aloe vera whole leaf extracts that differed in their anthraquinone content.
Superoxide dismutase and sodium azide inhibited and deuterium oxide enhanced the formation of lipid peroxides, suggesting that singlet oxygen and superoxide were involved in the mechanism.

It is concluded that superoxide anion was involved in the proposed chemiluminescence reaction because the chemiluminescence intensity was decreased only in the presence of superoxide dismutase.
Among the tested quinones, the chemiluminescence was observed from 9,10-phenanthrenequinone, 1,2-naphthoquinone, and 1,4-naphthoquinone, whereas it was not observed from 9,10-anthraquinone and 1,4-benzoquinone.
