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).

6-Fluoro-serotonin (6F-5-HT) was previously identified in the rat brain after peripheral administration of 6-fluoro-DL-tryptophan, a serotonin (5-HT) synthesis inhibitor. These present studies, performed with rat brain synaptosomes show that: i-neuronal 6F-5-HT uptake partly involved the 5-HT transporter since it was

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.

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.

Rotational-echo double-resonance (REDOR) 13C NMR spectra (with 19F dephasing) have been obtained of 6-fluorotryptophan complexed by a polymeric amphiphilic nanosphere consisting of a polystyrene core covalently attached to a poly(acrylic acid)-polyacrylamide shell. The REDOR spectra show that aromatic carbons from

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
