The Uses of L-4-Chlorophenylalanine

4-Chloro-L-phenylalanine is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals.

Definition

ChEBI: A non-proteinogenic L-alpha-amino acid that is L-phenylalanine in which the meta-hydrogen of the phenyl group has been replaced by a chlorine.

Biochem/physiol Actions

4-Chloro-L-phenylalanine (L-PCPA) inhibits the synthesis of 5-hydroxytryptamine (5-HT). 4-Chloro-DL-phenylalanine (PCPA) depletes the serotonin levels in the brain by its inhibitory effect on tryptophan hydroxylase (Tph). Studies support the protective effects of PCPA against monocrotaline-induced pulmonary vascular remodeling as well as in lung inflammation.
