| | L-KYNURENINE Usage And Synthesis |
| 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 | Store at RT | | References | References/Citations
