Metabolite Identification
Common NamePhaclofen
Description[3-amino-2-(4-chlorophenyl)propyl]phosphonic acid belongs to the class of organic compounds known as chlorobenzenes. Chlorobenzenes are compounds containing one or more chlorine atoms attached to a benzene moiety. Based on a literature review very few articles have been published on [3-amino-2-(4-chlorophenyl)propyl]phosphonic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Phaclofen is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Phaclofen is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Enzymes

General function:
Involved in G-protein coupled receptor activity
Specific function:
Isoform 1E function may be to regulate the availability of functional GABA-B-R1A/GABA-B-R2 heterodimers by competing for GABA-B-R2 dimerization. This could explain the observation that certain small molecule ligands exhibit differential affinity for central versus peripheral sites
