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 ]
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.
It is one of ten dihydroxyanthraquinone isomers. Its molecular structure can be viewed as being derived from anthraquinone by replacement of two hydrogen atoms (H) by hydroxyl groups (-OH). Xanthopurpurin occurs in small amounts (as a glycoside ) in the root of the common madder plant, Rubia tinctorum , together with alizarin , purpurin and ...
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.
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).
ITAMs are important for signal transduction, mainly in immune cells. They are found in the cytoplasmic tails of non-catalytic tyrosine-phosphorylated receptors [7] such as the CD3 and ζ-chains of the T cell receptor complex, the CD79-alpha and -beta chains of the B cell receptor complex, and certain Fc receptors.
Two-component systems accomplish signal transduction through the phosphorylation of a response regulator (RR) by a histidine kinase (HK). Histidine kinases are typically homodimeric transmembrane proteins containing a histidine phosphotransfer domain and an ATP binding domain, though there are reported examples of histidine kinases in the atypical HWE and HisKA2 families that are not ...
