deep red coarse crystalline powder | [Uses]
Aurintricarboxylic acid is employed as a powerful inhibitor of cellular processes, including apoptosis, that are dependent on the formation of protein-nucleic acid complexes. It binds to a FGF and reduces its angiogenic activity. Aurintricarboxylic Acid has been shown to inhibit apoptotic cell death in various cell types induced by a variety of factors. It Inhibits protein-nucleic acid interactions. It stimulates the tyrosine phosphorylation of MAP kinases. | [Uses]
endonuclease inhibitor; apoptosis inhibitor, topoisomerase II inhibitor | [Definition]
ChEBI: A member of the class of quinomethanes that is 3-methylidene-6-oxocyclohexa-1,4-diene-1-carboxylic acid in which the methylidene hydrogens are replaced by 4-carboxy-3-hydroxyphenyl groups. The trisodium salt is the biological stain 'chrome violet CG' while
the triammonium salt is 'aluminon'. | [Biological Activity]
Readily polymerizes in aqueous solutionforming a stable free radical th at inhibits protein-nucleic acid interactions. It is a potent inhibitor of ribonuclease and topoisomerase II by preventing the binding of the nucleic acid to the enzyme. It stimulates tyrosine phosphorylation processes including the Jak2/STAT5 pathway in NB2 lymphoma cells ErbB4 in neuroblastoma cellsand MAP kinasesShc proteinsphosphatidylinositide 3-kinase and phospholipase Cγ in PC12 cells. Inhibits apoptosis. It prevents down-regulation of Ca2+ -impermeable GluR2 receptors and inhibits calpaina Ca2+ -activated protease th at is activated during apoptosis. | [Purification Methods]
The acid is dissolved in aqueous NaOH, NaHSO3 solution is added until the colour is discharged and then the tricarboxylic acid is precipitated with HCl. [Heisig & Lauer Org Synth Coll Vol I 54 1941, Beilstein 10 IV 4161]. Do not extract the acid with hot water because it softens, forming a viscous mass. Make a solution in aqueous NH3. Aluminon is the NH4 salt. |
