r-aminobutyric acid

γ-Aminobutyric acid (4-Aminobutyric acid) is the predominant inhibitory neurotransmitter in the central nervous system.

Phenibut (Aminophenylbutyric acid) is a central depressant and derivative of the naturally occurring inhibitory neurotransmitter γ-aminobutyric acid (GABA).

Several different arachidonoyl amino acids, including N-arachidonoyl-3-hydroxy-γ-aminobutyric acid (NAG-3H-ABA), have been isolated and characterized from bovine brain. The glycine congener was further characterized and found to suppress formalin-induced pain in rats. NAG-3H-ABA was also found in rat brain by LC-MS techniques, but has not been fully characterized to date. Most arachidonoyl amino acids are poor ligands for the CB1 receptor.

Loreclezole is a selective GABAA receptor modulator and acts as a positive allosteric modulator of β2 or β3-subunit-containing receptors.

Vigabatrin Hydrochloride (γ-Vinyl-GABA hydrochloride) is a structural analog of the inhibitory neurotransmitter γ-aminobutyric acid (GABA), which irreversibly inhibits the catabolism of GABA by GABA transaminase.

rac-BHFF ((R,S)-BHFF) is potent and selective GABA B receptor positive allosteric modulator that increases the potency and efficacy of GABA ( > 15-fold and > 149% respectively). It exhibits anxiolytic activity in vivo and is orally active.

(+)-Kavain ((R)-KAWAIN) is one of the six major kavalactones found in the Piper methysticum (kava) plant; reversible inhibitor of MAO-B.

(R)-baclofen (STX209), a derivative of gamma-aminobutyric acid, is commonly utilized for the treatment of spasticity.

(R)-2-Hydroxybutanoic acid is an isomer of 2-Hydroxybutyric acid, often used as a control compound in experiments. 2-Hydroxybutyric acid (α-Hydroxybutyric acid) is derived from 2-Aminobutyric acid, with 2-oxobutyric acid serving as an intermediate metabolite.
