Evaluation of the effect of carnosine, its novel derivative trolox-carnosine and trolox in a pre-clinical study focussing on the regulation of immunity

The neuroprotective or neurotoxic effects of the products of the kynurenine pathway of tryptophan metabolism highly depend on the action of kynurenine-3-monooxygenase (KMO). The present results show increased concentrations of the KMO in the plasma of rats repeatedly exposed to an immune challenge. Increased concentrations of this key enzyme are likely to cause a shift of kynurenine pathway towards enhanced production of neurotoxic metabolites.
