Kynurenine and related metabolites play a significant role in the pathogenesis of major depressive disorder and schizophrenia. This paper is the review of literature data on the most modern state of this problem.</italic></p><p> </p></abstract><trans-abstract xml:lang="ru"><p><italic>Незаменимая аминокислота триптофан метаболизируется по метоксииндольному пути до серотонина, мелатонина и 5-гидроксииндолуксусной кислоты и по кинурениновому пути с образованием кинуренина и его нейроактивных метаболитов, таких как 3-гидроксикинуренин, кинуреновая, хинолиновая и ксантуреновая кислота.
