Application
L-Kynurenine sulfate salt has been used as a substrate to study the enzyme activity of kynurenine aminotransferase. It has also been used in the synthesis of Kyn adducts of certain amino acids .
Biochem/physiol Actions
L-Kynurenine (L-Kyn) is a precursor of kynurenic acid which is the only recognized endogenous excitatory amino acid receptor antagonist in the central nervous system. L-Kyn is known to be a pigment generating component in animals. In mammals, it modulates the transmission of glutamate neurotransmitter. It is also considered to be a sex-attracting pheromone in vertebrates.
Key intermediate in the breakdown pathway of tryptophan.
L-Kynurenine is a key intermediate in the breakdown of L-tryptophan and the formation of nicotinamide adenine dinucleotide (NAD+) via the kynurenine pathway. L-kynurenine is involved in a variety of neurological processes and diseases. L-kynurenine is a substrate for kynureninase/kynurenine hydrolase; kynurenine 3-monooxygenase and kynurenine-oxoglutarate transaminase.

The overactivation of excitatory amino acid receptors plays a key role in the pathomechanism of several neurodegenerative disorders and in ischemic and post-ischemic events. Kynurenic acid (KYNA) is an endogenous product of the tryptophan metabolism and, as a broad-spectrum antagonist
L-Kynurenine, an amino acid identified as a sex pheromone in the urine of ovulated female masu salmon.
