Metabolite Identification
Common NameProgabide
DescriptionProgabide, also known as halogabide or gabrene, belongs to the class of organic compounds known as o-quinomethanes. These are organic compounds containing a benzene ring conjugated to a methylidene group and a ketone at carbon atoms 1 and 2, respectively. Binding to GABAA results in an increased affinity of the GABA receptor for the amino acid, an augmented flux of chloride ions across the terminal membrane, and an increase in the amount of presynaptic inhibition. Progabide is a strong basic compound (based on its pKa). Progabide is an analog and prodrug of gamma-aminobutyric acid. Progabide is a potentially toxic compound. May cause a potentially dangerous rash that may develop into Stevens Johnson syndrome, an extremely rare but potentially fatal skin disease. It has agonistic activity for both the GABAA and GABAB receptors. Activation of the GABAB receptors retards the influx of calcium ions into the terminals, thereby reducing the evoked release of excitatory amino acids and possibly other transmitters.

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
