Product information "Aurintricarboxylic Acid (ammonium salt)"
Aurintricarboxylic acid (ATA) is an inhibitor of protein synthesis that has diverse biological activities. It inhibits the activity of a variety of enzymes, including the nucleases DNase I, RNase A, and S1, as well as the serine proteases trypsin and chymotrypsin in a concentration-dependent manner. ATA inhibits replication of severe acute respiratory syndrome coronavirus (SARS-CoV, EC50 = 200 µg/ml) and human enterovirus 71 in Vero cells (EV71, EC50 = 2.9 µM), as well as reduces HIV-1- or HIV-2-induced cytopathogenicity in MT-4 cells (IC50s = 1.1 and 0.85 µg/ml, respectively). It inhibits apoptosis induced by sanguinarine (Cay-16951) in K562 leukemia cells when used at a concentration of 100 µM. ATA (20 mg/kg, i.p.) decreases CNS CD4+ T cell infiltration and reduces hind limb weakness and paralysis in a mouse model of myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis (EAE).Formal Name: 3,3'-[(3-carboxy-4-oxo-2,5-cyclohexadien-1-ylidene)methylene]bis[6-hydroxy-benzoic acid, triammonium salt.
