Descripción

Application

• Aurintricarboxylic acid has been used to show its anticryptosporidial activity against Cryptosporidium parvum.
• It has been used as a test substance to identify inhibitors against coronavirus N7-MTases (guanine-N7-methyltransferase).
• It has been used as a ribonuclease inhibitor.

Biochem/physiol Actions

Readily polymerizes in aqueous solution, forming a stable free radical that 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 cells, and MAP kinases, Shc proteins, phosphatidylinositide 3-kinase and phospholipase Cγ in PC12 cells. Inhibits apoptosis. It prevents down-regulation of Ca²⁺ -impermeable GluR2 receptors and inhibits calpain, a Ca²⁺ -activated protease that is activated during apoptosis.
