Fenclonine, also known as p-chlorophenylalanine, is an inhibitor of tryptophan hydroxylase, the enzyme that plays a rate-limiting role in the biosynthesis of serotonin. Fenclonine was studied for the treatment of carcinoid syndrome, but the psychological side effects, prevented for the further development for this use.
