Aminoacids and derivatives

<p>Applications 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.<br>References Turner, R.
