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 ...

Synthesis of fluorine-substituted anthraquinones and aza-anthraquinones

Journal of Fluorine Chemistry, 1994
Abstract Using 1,4-dipolar-aryne cycloaddition methodology, a convenient, short synthesis of several fluoroanthraquinones is presented which involves the reaction of haloarenes and 3-cyanophthalides in the presence of lithium diisopropylamide (LDA) in tetrahydrofuran (THF).

Stereochemical Studies on Pre-Anthraquinones and Dimeric Anthraquinone Pigments

1988
Labelling studies have shown that the biosynthesis of emodin (6) and related anthraquinone pigments in fungi and higher plants occurs via the acetate/malonate pathway (ref. 1). Details of the early steps in this biosynthesis, however, remain unknown.

Anthraquinones, pre-anthraquinones and isoeleutherol in the roots of Aloe species

Phytochemistry, 1994
Abstract Comparative TLC analysis of the root extracts of 32 Aloe species showed that chrysophanol, asphodelin, chrysophanol-8-methyl ether, aloechrysone, helminthosporin, aloesaponol III, aloesaponarin I, aloesaponol I, aloesaponarin II, aloesaponol II and laccaic acid D-methyl ester are widely distributed in these plants.

Anthraquinones in the fungusTalaromyces stipitatus

Experientia, 1973
Drei Anthrachinonpigmente wurden aus dem SchimmelpilzTalaromyces stipitatus CBS 349.72 isoliert. Die Untersuchung zeigte, dass sie Verbindungen identisch sind mit Erythroglaucin, Catenarin und Emodin. Durch Vergleich mit authentischen Proben konnte diese Ansicht bestatigt werden.

Anthraquinones in Caloplaca

Phytochemistry, 1970
Abstract About 230 species of the lichen genus Caloplaca have been surveyed for anthraquinones. By means of lichen mass spectrometry and TLC, emodin, parietin, fallacinol, fallacinal, parietinic acid, xanthorin, 2-chloroemodin, fragilin, and 1- O -methylfragilin have been identified, as well as some non-anthraquinonoid compounds.
