| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| biological activity | 4-chloro-dl-phenylalazine (fenclonate, PCPA, CP-10188) is a selective irreversible inhibitor of tryptophan hydroxylase. Tryptophan hydroxylase is the rate-limiting enzyme in the synthesis of serotonin (5-hydroxytryptamine). 4-Chloro-DL-phenylalanine can deplete endogenous serotonin levels. |
