N-Acetyl-L-Tryptophan (Ac-Trp-OH) (CAS: 1218-34-4) is a N-acetyl-L-amino acid that is the N-acetyl derivative of L-Tryptophan.
1. N-Acetyl-L-Tryptophan is widely used in pharmaceutical, chemical and biological industries.
2. N-Acetyl-L-Tryptophan has been used as a protein stabolizer. It prevents protein molecules from oxidative degradation by scavenging oxygen dissolved in protein solutions.
3. N-Acetyl-L-Tryptophan is also used as a competitive inhibitor to identify, differentiate and characterized tryptophanase(s).
4. N-Acetyl-L-Tryptophan is a brain supplement that has quickly grown in popularity.
5. N-Acetyl-L-Tryptophan, is a derivative of L-Tryptophan, 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.
6. Nutritional supplement. Amino acids. Mainly used for amino acid infusion, due to special wettability, also used in cold cream, cosmetics, constitute the human body of several kinds of essential amino acid of protein a, for the construction of protein has a very important role.
Safety Profile: Moderately toxic by some routes. An experimental teratogen. Other experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOX.
