+3-Hydroxy-Anthranilic acid
Tryptophan catabolism can be initiated by either indoleamine 2,3 dioxygenase 1 and 2 (IDO1 and IDO2) or the tryptophan 2,3 dioxygenase 2 (TDO2) to produce a series of catabolites collectively known as kynurenines. This pathway has been extensively studied for its immune regulatory functions. The production of 3-hydroxy-Anthranilic acid (3HAA) is thought to play a key role in this phenomenon, with PDK1 being the only molecular target identified. Also, 3HAA has been shown to exert anti-inflammatory effects when administered in an experimental model of multiple sclerosis mice (EAE).
