N-Acetyl-L-tryptophan Usage And Synthesis

Chemical Properties	solid
Uses	N-Acetyl-L-Tryptophan, is a derivative of L-Tryptophan (T947210), that can be used as competitive inhibitor to identify and characterize tryptophanases. It can also be used as an NK1 tachykinin receptor antagonist, that may help to develop a novel therapeutic intervention for the treatment of reperfusion injury in acute ischemic stroke.
Definition	ChEBI: A N-acetyl-L-amino acid that is the N-acetyl derivative of L-tryptophan.
Safety Profile	Moderately toxic by some routes. An experimental teratogen. Other experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOX,.
