A dihydroxyanthraquinone is any of several isomeric organic compounds with formula (C 12 H 6 (OH) 2)(CO) 2, formally derived from 9,10-anthraquinone by replacing two hydrogen atoms by hydroxyl groups. Dihyroxyantraquinones have been studied since the early 1900s, and include some compounds of historical and current importance.
1,4-Dihydroxyanthraquinone, also called quinizarin or Solvent Orange 86, is an organic compound derived from anthroquinone. Quinizarin is an orange or red-brown crystalline powder. It is formally derived from anthraquinone by replacement of two hydrogen atoms by hydroxyl (OH) groups.
1,5-Dihydroxyanthraquinone is an organic compound with the formula (C 6 H 3 OH) 2 (CO) 2. It is one of several isomers of dihydroxyanthraquinone . An orange solid, it is a component of traditional Chinese medications. [ 3 ]
1,3-Dihydroxyanthraquinone, also called purpuroxanthin or xanthopurpurin, is an organic compound with formula C 14 H 8 O 4 that occurs in the plant Rubia cordifolia (Indian madder). [1] It is one of ten dihydroxyanthraquinone isomers.
They are also known as danger signals, and alarmins because they serve as warning signs to alert the organism to any damage or infection to its cells. DAMPs are endogenous danger signals that are discharged to the extracellular space in response to damage to the cell from mechanical trauma or a pathogen. [ 3 ]

Dantron , also known as chrysazin or 1,8-dihydroxyanthraquinone, is an orange-colored organic substance. Many structurally-related compounds are known. [ 1 ] In terms of its molecular structure, it is related anthraquinone by the replacement of two hydrogen atoms by hydroxyl groups (–OH).
In cell biology, a biological pathway is a series of interactions among molecules in a cell that leads to a certain product or a change in the cell. Such a pathway can trigger the assembly of new molecules, such as a fat or protein.
