5-FLUORO-DL-TRYPTOPHAN Usage And Synthesis

Chemical Properties

light beige powder

Uses

A metabolic antagonist of tryptophan

Definition

ChEBI: A non-proteinogenic alpha-amino acid that is tryptophan in which the hydrogen at position 5 on the indole ring is replaced by a fluoro group.

Purification Methods

Recrystallise it from EtOH, aqueous EtOH or AcOH. Also purify it by passage through a Dowex AG1x2 (acetate form) column and recrystallise the L-enantiomer (from enzymic enrichment) from H2O/EtOH, m 158-163o(dec), [] D -8.3o (c 2.5, N NaOH). [Coy et al. Biochemistry 13 3550 1974, Beilstein 22/14 V 116.]
