Biological Activity

Description Xanthurenic acid, a molecule arising from tryptophan metabolism by transamination of 3-hydroxykynurenine, activates mGlu2/3 Metabotropic glutamate receptors (mGlu2 and mGlu3).
Targets
mGlu2 [1]
()
mGlu3 [1]

In vitro

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[1]. 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[2].

In vivo 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[1].

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
