Talk:Anthraquinone

Solubility

In the article, it says that anthraquinone is semisoluble in water, and in the box, it is insoluble ! Is it very poorly soluble ? Tiphaine800 (talk) 08:37, 5 February 2008 (UTC)

It seems that this has been fixed already. --Jorge Stolfi (talk) 19:34, 31 January 2010 (UTC)

"Anthrachinon"

The infobox (and formery the ext) gave "9,10-anthrachinon" as an alternate name. Isn't this the *German* name? If so we can leave it for the German Wikipedia, methinks. --Jorge Stolfi (talk) 19:34, 31 January 2010 (UTC)

"Anthroquinone"

Google gives some 19,000 hits for "anthroquinone". Is this just a common typo, or is it so common that it should be considered an alternate name? (I note that "naphthAlene" gives "naphthOquinone", "benzene" gives "benzOquinone", so perhaps "anthroquinone" is just the applicaion of a presumed or unpopular general rule?) All the best, --Jorge Stolfi (talk) 19:34, 31 January 2010 (UTC)

Merge with anthracenedione

I am not a chemist, but from the little I know I got the impression that "antracenedione" and "anthraquinone" are largely synonyms. Both usually mean the specific compound 9,10-dioxoanthracene, but may also mean any other dioxoanthracene, or any derivative thereof. Is this impression correct? If so, I propose a merge of the two articles. All the best, --Jorge Stolfi (talk) 01:40, 2 February 2010 (UTC)

This article is greatly improved

Nice work, especially by someone who is supposedly not a chemist. Your instincts are right on, do the merge (the other article looks like junk compared to this one) and follow your sense. I will be in limited action for a while, chewing on insects...

One thing that we might incorporate one of these years is the initial isolation etc. Here is a quote from Ullmann's encyclopedia "In 1835, anthraquinone was prepared for the first time by Laurent, via oxidation of anthracene,... Its special importance ... was recognized only in 1868 when Graebe and Liebermann prepared anthracene from alizarin (1,2-dihydroxyanthraquinone) and, in turn, alizarin via anthraquinone. This laid the groundwork..."--Smokefoot (talk) 03:23, 2 February 2010 (UTC)

Medicine

Derivatives of 9,10-anthraquinone include many important drugs (collectively called anthracenediones). They include

• Laxatives such as dantron, emodin, and aloe emodin, and some of the senna glycosides
• Antimalarials such as rufigallol
• Antineoplastics used in the treatment of cancer, such as mitoxantrone, pixantrone, and the anthracyclines
• DNA dyes / nuclear counterstains such as DRAQ5, DRAQ7 and CyTRAK Orange for flow cytometry and fluorescence microscopy.

Aloe emodin

Mitoxantrone

Pixantrone

• An anticholinergic agent called elantrine is made from Anthraquinone.
• Another use of anthraquonone is in the synthesis of Danitracen (WA-355) – an antidepressant; sedative; antihistamine.
• Anthraquinone is also used to make Prazepine & possibly also Enprazepine.
