Abstract
The kynurenine pathway represents the major biochemical route for the metabolism of L-tryptophan in mammals. The pathway is particularly important in the central nervous system (CNS), since the ‘precursor responsiveness’ of the pathway exceeds that of tryptophan metabolism via 5-hydroxytryptamine (Freese et al. 1990; Stone, 1993).. Any procedure which alters the systemic availability of tryptophan will therefore have important consequences for CNS function. In particular, it is now well established that within the CNS, the kynurenine pathway lead to the formation of two compounds — quinolinic acid and kynurenic acid — with activity at receptors for neurotransmitter amino acids.
