γ-aminobutyric acid receptor

Broflanilide is metabolized to desmethyl-broflanilide, which is a potent antagonist at the insect resistant-to-dieldrin GABA receptor and inhibits S. litura RDL GABAR (IC50: 1.3 nM).

Riluzole (RP-54274) is a glutamate antagonist (RECEPTORS, GLUTAMATE) used as an anticonvulsant (ANTICONVULSANTS) and to prolong the survival of patients with AMYOTROPHIC LATERAL SCLEROSIS.

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

L-Cycloserine ((-)-Cycloserine) irreversibly inhibits GABA pyridoxal 5′-phosphate-dependent aminotransferase in E. coli, as well in the brains of various animals, results in increased levels of gamma-aminobutyric acid (GABA), which is an inhibitory neurotransmitter in vivo.

Baclofen (Lioresal) is a synthetic chlorophenyl-butanoic acid derivative used to treat spasms due to spinal cord damage and multiple sclerosis, muscle-relaxing Baclofen acts as a gamma-aminobutyric acid (GABA) agonist specific for GABA-B receptors. It acts at spinal and supraspinal sites, reducing excitatory transmission.

Flumazenil (Ro 15-1788) antagonizes the benzodiazepine binding site of the gamma-aminobutyric acid (GABA)/benzodiazepine receptor complex in the central nervous system (CNS), thereby preventing the chloride channel opening events and inhibiting neuronal hyperpolarization. As a result, flumazenil reverses benzodiazepine-induced effects including sedation, psychomotor deficits, amnesia, and hypoventilation in a dose-dependent manner. Flumazenil is an imidazobenzodiazepine derivative, effective in reversing benzodiazepine-induced activities.

Pivagabine (CXB-722), a hydrophobic 4-aminobutyric acid derivative, exhibits neuromodulatory activity and successfully penetrates the blood-brain barrier in rats. It counteracts the impact of foot shock on GABAA receptor function and corticotropin-releasing factor (CRF) levels in the rat brain.

Bemegride (3-Ethyl-3-methylglutarimide), a central nervous system stimulant, serves as an antidote for barbiturate poisoning.

Clomethiazole (Distraneurin) is an orally active GABAA agonist and it is an anticonvulsant agent. It also has the potential for treating convulsive status epilepticus. Chlormethiazole inhibits cytochrome P450 isoforms: CYP2A6 and CYP2E1 in human liver microsomes.

Fipronil (Fluocyanobenpyrazole) is a broad-use insecticide that belongs to the phenylpyrazole chemical family. Fipronil is a broad-spectrum insecticide that disrupts the insect central nervous system by blocking GABA-gated chloride channels and glutamate-gated chloride (GluCl) channels, resulting in central nervous system toxicity. This causes hyperexcitation of contaminated insects' nerves and muscles. Specificity of fipronil on insects may come from a better efficacy on GABA receptor, but also because GluCl channels do not exist in mammals.

DL-Menthol ((±)-Menthol) is a racemic mixture of the monoterpene alcohols (–)-menthol and (+)-menthod, which have been found in Cannabis. (–)-Menthol is more common than (+)-menthol in nature and exhibits analgesic, antibacterial, and anticancer properties, as well as inhibits cholinesterase.2 (+)-Menthol inhibits the growth of F. verticillioides (MIC: 1.5 mM) but, unlike (–)-menthol, does not exhibit analgesic, antibacterial, anticancer, or cholinesterase inhibitory activities.

3,4,5-Trimethoxycinnamic acid (O-Methylsinapic acid) (TMCA) is one of the constituents of Polygalae Radix and may exert anti-seizure activity by acting at the GABAA/BZ receptor complex.

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

4-Acetamidobutanoic acid (4-ACETAMIDOBUTYRIC ACID) can be found in blood, feces, and urine, as well as in human prostate tissue. 4-Acetamidobutanoic acid exists in all eukaryotes, ranging from yeast to humans. 4-Acetamidobutanoic acid is a GABA derivative, a product of the urea cycle and the metabolism of amino groups, and the product of NAD-linked aldehyde dehydrogenase (EC 1.2.1.3) (KEGG).

Aminooxyacetic acid hemihydrochloride (Carboxymethoxylamine Hemihydrochloride) is a malate-aspartate shuttle (MAS) inhibitor which also inhibits the GABA degradating enzyme GABA-T.

Cholesterol Myristate (Cholesteryl Myristate) is a natural steroid found in traditional Chinese medicine that interacts with various ion channels, including the GABAA receptor, nicotinic acetylcholine receptor, and the inward-rectifier potassium ion channel.

(-)-α-Pinene ((1S)-(-)-Alpha-Pinene) enhances the quantity of NREMS without affecting the intensity of NREMS by prolonging GABAergic synaptic transmission, acting as a partial modulator of GABAA-BZD receptors and directly binding to the BZD binding site of GABAA receptor.

(E)-3,4,5-Trimethoxycinnamic acid (O-Methylsinapic acid) is a natural compound derived from the roots and rhizomes of Notopterygium incisum.

Etifoxine hydrochloride (HOE 36-801 hydrochloride) is an anxiolytic and anticonvulsant drug. Unlike benzodiazepines, Etifoxine hydrochloride appears to produce its anxiolytic effects by binding to β2 and β3 subunits of the GABAA receptor complex, and so is acting at a different target site to benzodiazepines, although the physiological effect that is produced is similar to that of benzodiazepines.

Pikamilone (Picamilon) is an intelligent medicine.

CL 218872 is a benzodiazepine agonist displaying selectivity for α1 subunit-containing GABAA receptors (Ki values are 130, 1820, 1530, > 10000, 490 and > 10000 nM for α1, α2, α3, α4, α5 and α6-subunit containing receptors respectively). Orally active anxi

Chlormezanone (Trancopal) is a non-benzodiazepine that is used in the management of anxiety. It has been suggested for use in the treatment of muscle spasm.

FG 7142 (LSU-65) also modulates GABA-induced chloride flux at GABAA receptors expressing the α1 subunit (EC50= 137 nM). FG 7142 can increase tyrosine hydroxylation and cause upregulation of β-adrenoceptors in mouse cerebral cortex. FG 7142 , a non-selectively benzodiazepine inverse agonist, has high affinity for the α1 subunit-containing GABAA receptor (Ki=91 nM).

Oxiracetam (ISF2522), a cyclic derivative of gamma-aminobutyric acid (GABA), is utilized for the treatment of cognitive impairments.
