6-fluoro-DL-Tryptophan

Tryptophan is an amino acid precursor of serotonin (Item No. 14332) and melatonin (Item No. 14427). 6-fluoro-DL-Tryptophan is a serotonin synthesis inhibitor that is metabolized in the brain and may be useful for tracing pools of neuronal serotonin.{28783,28784} It is used as a competitive inhibitor of tryptophan binding to albumin and can behave as a substrate for the serotonin neural transporter for passage through the blood brain barrier.{28783,28784,28782}
