Redox‐Active Organic Sodium Anthraquinone‐2‐Sulfonate (AQS) Anchored on Reduced Graphene Oxide for High‐Performance Supercapacitors

Advanced Energy Materials, 2018
Redox active organic quinones are potentially low cost, sustainable, and high‐energy pseudocapacitive materials due to their fast and reversible redox reactivity. However, their electrically insulating nature prevents any practical application.

Anthraquinones from Gladiolus gandavensis

Journal of Asian Natural Products Research, 2005
Five new anthraquinones have been obtained from the ethanolic extracts of the subterranean corms of Gladiolus gandavensis Van Houtt. Their structures were elucidated as 3,8-dihydroxy-6-methoxy-1-methyl-anthraquinone (gandavensin D, 1), methyl 3,8-dihydroxy-6,7-methylenedioxy-1-methyl-anthraquinone- 2-carboxylate (gandavensin E, 2), 2,3,8-trihydroxy-6 ...

2,3-Diethoxy-9,10-anthraquinone

Acta Crystallographica Section C Crystal Structure Communications, 2008
Anthraquinone derivatives form an important class of dyes and are also known for their medicinal properties. Recently, 2,3-disubstituted anthraquinones have been shown unexpectedly to jellify various organic solvents. No information on the packing mode of these derivatives was known.

In vitro virucidal activity of selected anthraquinones and anthraquinone derivatives

Antiviral Research, 1991
Anthraquinones and anthraquinone derivatives were characterized for their antiviral and virucidal activities against viruses representing several taxonomic groups. One of these compounds, hypericin, had activity against vesicular stomatitis virus, herpes simplex virus types 1 and 2, parainfluenza virus, and vaccinia virus (from 0.5 to 3.8 log10 ...
