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
