Application

6-Fluoro-DL-tryptophan (6-F-TRP), a serotonin (5-HT) synthesis inhibitor, is metabolized in the brain and may be useful for tracing neuronal serotoninergic pools. 6-F-TRP is used as a competitive inhibitor of tryptophan binding to albumin and passage through the blood brain barrier (BBB).

1. Within triads of rats, individuals can be discerned according to their competition for sucrose-pellets as a high-, a medium- and a poor-performing animal. 2. The competition-rates, expressed as scores, are affected by serotonergic drugs: upon inhibiting tryptophan-hydroxylase, the characteristic

We administered 6-fluoro-DL-tryptophan (6F-Trp) to rats (50-200 mg/kg i.p.) and evaluated its neurochemical effects on central catechole and indole compounds; we also determined the time course of its action, together with its metabolism and kinetics in four rat brain areas.

Rat cellular retinol-binding protein II (CRBP II) is a 15.6-kDa intestinal protein which binds all-trans-retinol and all-trans-retinal but not all-trans-retinoic acid. We have previously analyzed the interaction of Escherichia coli-derived rat apoCRBP II with several retinoids using fluorescence spectroscopic techniques.

After intraperitoneal injection of rats with 6-fluorotryptophan (6-FT), brain 5-hydroxytryptamine (5-HT) levels decreased exponentially over 1 h. Depletion was dose-dependent and maximum depletion was observed at 200 mg/kg. 6-FT (200 mg/kg) did not significantly alter the content of 5-hydroxyindoleacetic acid.

An immunoblot procedure was developed to quantify the amount of tryptophan hydroxylase (TpOH), the rate limiting enzyme in the synthesis of serotonin, in the rat raphe dorsalis nucleus (NRD). Using this method we have studied the time course variations in
