(S)-2-AMINO-3-(5-FLUORO-1H-INDOL-3-YL)-PROPIONIC ACID Chemical Properties,Uses,Production

Uses

Exogenous 5-fluoro-Trp is incorporated into proteins in normal protein synthesis. Since ¹⁹F is a useful reporter group, this provides a method for studying enzyme mechanisms by NMR.

Biochem/physiol Actions

5-Fluoro-Trp is nonspecifically cytotoxic. It is believed this is due to malfunctioning enzymes that have had replacements of Trp residues by 5-fluoro-Trp. However, at least one case is known where 5-fluoro-Trp substitution leads to significantly greater catalytic activity.

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).
