| Hazard Information | Back Directory | [Description]
Kynurenine (2922-83-0) is a tryptophan catabolite.1?Endogenous tumor-promoting ligand of the human aryl hydrocarbon receptor (AhR). Constitutively generated by human tumor cells via the action of the tryptophan degrading enzyme, tryptophan-2,3-dioxygenase (TDO). Kynurenine suppresses antitumor immune responses and promotes tumor cell survival and motility.2 | [Uses]
L-Kynurenine has been used as a standard for indoleamine-2,3-dioxygenase (IDO) assay. It has also been used as a standard to extract and quantify kynurenine from cultured cells and media. | [Definition]
ChEBI: A kynurenine that has L configuration. | [Biochem/physiol Actions]
Key intermediate in the breakdown pathway of tryptophan. | [storage]
