L-Kynurenine is an active metabolite of tryptophan (Cay-29600, Cay-31210). It is formed from tryptophan via tryptophan 2,3-dioxygenase (TDO) or indoleamine 2,3-dioxygenase (IDO). L-Kynurenine binds to the aryl hydrocarbon receptor (AhR, Kd = ~4 µM) and increases the activity of ethoxyresorufin-O-deethylase (EROD) in...

Description: L-Kynurenine ((S)-Kynurenine) is a key intermediate in the breakdown pathway of tryptophan. L-Kynurenine is a substrate of kynureninase, KMO, and KAT associated with the suppression of antitumor immune responses. It has been shown to inhibit allogeneic T-cell proliferation and to increase malignant U87...

Amino acids are the basic units of proteins, which are linked by peptide bonds to form polypeptide chains that fold into proteins with specific functions. There are 20 common standard amino acids in nature, primarily distinguished by their side chains (R-groups). These differences give amino acids different...
