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,.
