6-fluoro-DL-Tryptophan is a serotonin (5-HT) synthesis inhibitor.
Serotonin or 5-hydroxytryptamine (5-HT), a monoamine neurotransmitter, is biochemically derived from tryptophan. Serotonin is primarily present in the gastrointestinal tract, blood platelets, and the central nervous system of animals. Serotonin is considered to be a contributor to feelings of well-being and happiness.
In vitro: The potential competition was investigated between L-tryptophan (TRP) and 6-fluoro-DL-tryptophan (6-F-TRP). In equilibrium dialysis experiments, albumin bound about 80% of TRP and 50% of 6-F-TRP. Competitive inhibition was assessed as the decrease in the apparent Ka of TRP in the presence of 6-F-TRP, with no modification of the N value [1].
In vivo: Rats werer administered 6-fluoro-DL-tryptophan (6F-Trp) and its neurochemical effects on central catechole and indole were evaluated. Results showed that neither norepinephrine nor dopamine and its major metabolites were affected by 6F-Trp. With regard to serotonin (5-HT), 6F-Trp could induce a transient depletion in all the studied brain areas, with a maximum of about 60-65% obtained between 1 and 3 hr. After 6 hr, 5-HT levels returned to control values. In addition, the 5-hydroxyindolacetic acid (5-HIAA) level was also reduced 3 hr after 6F-Trp administration. A large dose-dependent increase in tryptophan was seen in the four brain areas, mainly due to an inhibition of tryptophan incorporation into protein, as demonstrated by experiments with mouse neuroblastoma cells [2].
Clinical trial: So far, no clinical study has been conducted.
