Acetyltryptophan, L- functions readily as a component of the food in place of the free amino acid. Acetyltryptophan, L- is a neurokinin-1 receptor antagonist. It significantly improved motor and cognitive outcomes in models of Parkinson’s diseases, as well as reduced brain edema and axonal injury in experimental traumatic brain injury and stroke. It is a potent therapeutic agent for the treatment of amyotrophic lateral sclerosis.

Incubation with Acetyltryptophan,L- resulted in statistically significant inhibition of H2O2-mediated NSC-34 motoneuron cell death. The resulting curve (plotted semi-logarithmically) define the IC50 and maximum protection afforded by acetyltryptophan, L- (0.3 uM and 47%, respectively).
