D-2-AMINO-3-(5-HYDROXYINDOLYL)PROPIONIC ACID Chemical Properties,Uses,Production
Uses
D-5-Hydroxytryptophan (D-5-HTP) is the D-isomer of 5-HTP and can be isolated from DL-5-hydroxytryptophan by continuous separation. Compared with intraperitoneal administration of L-5-Hydroxytryptophan, which can induce dose-dependent backward walking behavior in mice, D-5-Hydroxytryptophan has no significant effect on mouse behavior and is a negative control. D-5-Hydroxytryptophan is also a 5-HT ligand, capable of binding to the 5-HT site with affinity in the micromolar range[1][2][3].
Definition
ChEBI: The D-enantiomer of 5-hydroxytryptophan.
in vivo
D-5-Hydroxytryptophan (100, 320 mg/kg; ip; single dose) cannot induce backward walking behavior in mice, while L-5-Hydroxytryptophan can do it[3].
