Kynurenic acid has been used as a constituent in dissection saline solution for embryonic cerebral cortical cells[7]and human primary astrocytes.[8]It has also been used as a medium supplement for murine intestinal epithelial cell line MODE-K[9]and induced pluripotent stem cell (iPSC)-derived neurons cells.

Kynurenic acid (KYNA or KYN) is a product of the normal metabolism of amino acid L-tryptophan. It has been shown that kynurenic acid possesses neuroactive activity. It acts as an antiexcitotoxic and anticonvulsant most likely through acting as an antagonist at excitatory amino acid receptors. Because of this activity it may influence important neurophysiological and neuropathological processes. As a result kynurenic acid has been considered for use in therapy in certain neurobiological disorders. Conversely increased levels of kynurenic acid have also been linked to certain pathological conditions.
