The kynurenine pathway, the main metabolic route of tryptophan degradation, produces several neuroactive molecules. Alterations in the kynurenine pathway have been described in a number of neurological disorders; a feature of special importance is the elevation of neurotoxic metabolites, which may promote glutamate- mediated excitotoxic neuronal damage. The delicate balance between the neurotoxic and neuroprotective compounds participating in the kynurenine pathway has been suggested to play an important role in the regulation of glutamatergic neurotransmission and in infl ammatory processes. Synthetic kynurenic acid derivatives and kynurenine-monooxygenase inhibitors have proved in several preclinical studies to have benefi cial effects. The kynurenine pathway offers a promising target for future drug development with the aim of achieving neuroprotection.
