Description
Curator's Comment: The description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/526758 | https://www.ncbi.nlm.nih.gov/pubmed/4587003 | https://www.ncbi.nlm.nih.gov/pubmed/10226937 | https://www.ncbi.nlm.nih.gov/pubmed/28551532

Kynurenine is a metabolite of the amino acid L-tryptophan used in the production of niacin. Kynurenine is synthesized by the enzyme tryptophan dioxygenase, which is made primarily but not exclusively in the liver, and indoleamine 2,3-dioxygenase, which is made in many tissues in response to immune activation. Kynurenine and its further breakdown products carry out diverse biological functions, including dilating blood vessels during inflammation and regulating the immune response. Evidence suggests that increased kynurenine production may precipitate depressive symptoms associated with interferon treatment for hepatitis C. Cognitive deficits in schizophrenia are associated with imbalances in the enzymes that break down kynurenine. Kynurenine production is increased in Alzheimer's disease and cardiovascular disease where its metabolites are associated with cognitive deficits and depressive symptoms.

Sample Use Guides

200-mg oral administration of L-kynurenine sulfate as a single dose.
Route of Administration: Oral
To measure the effect of the tested compounds (Kynurenine, 5, 10, 50 mkM) on the proliferation and viability of cells, a colorimetric assay was performed based on the cleavage of the water-soluble WST-1 (4- [3-(4-iodophenyl)-2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-ben- zene disulphonate) (tetrazolium salt) (Roche Diagnostics GmbH, Mannheim, Germany) by succinate dehydrogenase. Cells were incubated for a duration of 0–24 h and 24–48 h. At the end of the respective incubation period the medium was removed from the bottom part of the plate. 540 mkl of fresh medium without tested substances and 60 mkl of WST-1 solution (a concentration ready for use) were added and cells were incubated at 37 C and 5% CO2 for 3 h. Next, the culture supernatants were collected and 100 mkl of each in the replicates was added to a 96-well microplate and the absorbance was measured at 450 nm using a microplate reader
