Xanthurenic acid (XA) is considered as a putative neurotransmitter in the CNS, being stored in synaptic vesicles and released by membrane depolarization in a Ca2+-dependent fashion. It is known to inhibit vesicular glutamate transporters (VGLUTs). In heterologous expression systems, Xanthurenic acid could activate both mGlu2 and mGlu3 receptors with high potency, but has no activity on mGlu4 and mGlu7 receptors. Xanthurenic acid induces cell death associated with caspase-3, -8, and -9 activation, nuclear DNA cleavage, and cytochrome C release while not associated with cytoskeleton breakdown -- apoptosis induced by xanthurenic acid does not cause cytoskeleton depolymerization.

Systemic administration of Xanthurenic acid in mice produces antipsychotic-like effects in the MK-801-induced model of hyperactivity and peripheral xanthurenic acid can cross the blood-brain barrier, influence the activity of brain regions that are involved in the pathophysiology of schizophrenia.
