Kynurenine: A metabolite of the essential amino acid tryptophan metabolized via the tryptophan-kynurenine pathway.
kynurenine : A ketone that is alanine in which one of the methyl hydrogens is substituted by a 2-aminobenzoyl group.
Depressive Disorder, Treatment-Resistant: Failure to respond to two or more trials of antidepressant monotherapy or failure to respond to four or more trials of different antidepressant therapies. (Campbell's Psychiatric Dictionary, 9th ed.)
