Gamma-Amino acids

GABA (gamma-aminobutyric acid, γ-aminobutyric acid) is the chief inhibitory neurotransmitter in the developmentally mature mammalian central nervous system. Its principal role is reducing neuronal excitability throughout the nervous system.

Pregabalin, sold under the brand names Axalid and Lyrica among others, is an anticonvulsant, analgesic, and anxiolytic amino acid medication used to treat epilepsy, neuropathic pain, fibromyalgia, restless legs syndrome, opioid withdrawal, generalized anxiety disorder (GAD), and postherpetic neuralgia (a type of nerve damage that can result from shingles). Pregabalin also has antiallodynic properties. Its use in epilepsy is as an add-on therapy for partial seizures. When used before surgery, it reduces pain but results in greater sedation and visual disturbances. It is taken by mouth.

Gabapentin, sold under the brand name Neurontin among others, is an anticonvulsant medication used to treat neuropathic pain (postherpetic neuralgia) and partial seizures of epilepsy. Gabapentin is a central nervous system (CNS) depressant and derivative of the inhibitory neurotransmitter, GABA. It is used for the treatment of neuropathic pain caused by diabetic neuropathy, postherpetic neuralgia, and central pain. It is moderately effective: about 30–40% of those given gabapentin for diabetic neuropathy or postherpetic neuralgia have a meaningful benefit.

Baclofen, sold under the brand name Lioresal among others, is a central nervous system (CNS) depressant and derivative of the inhibitory neurotransmitter, γ-Aminobutyric acid (GABA). It is a skeletal muscle relaxant medication used to treat muscle spasms, muscle spasticity, such as from a spinal cord injury or multiple sclerosis. Baclofen is a potent GABAB receptor agonist. It may also be used for hiccups and muscle spasms near the end of life, and off-label to treat alcohol use disorder or opioid withdrawal symptoms. It is taken orally or by intrathecal pump (delivered into the spinal canal v

Vigabatrin, sold under the brand name Vigafyde among others, is a medication used in the management and treatment of infantile spasms and refractory complex partial seizures.

Phenibut, sold under the brand name Anvifen among others, is a central nervous system (CNS) depressant with anxiolytic effects, and is used to treat anxiety, insomnia, and for a variety of other indications. It is usually taken orally (swallowed by mouth), but may be given intravenously.

Glutamate-1-semialdehyde is a molecule formed from by the reduction of tRNA bound glutamate, catalyzed by glutamyl-tRNA reductase. It is isomerized by glutamate-1-semialdehyde 2,1-aminomutase to give aminolevulinic acid in the biosynthesis of porphyrins, including heme and chlorophyll.

Difenoxin (Motofen, R-15403) is an opioid drug used, often in combination with atropine, to treat diarrhea. It is the principal metabolite of diphenoxylate.

Statine is a gamma amino acid that occurs twice in the sequence of pepstatin, a protease inhibitor that is active against pepsin and other acid proteases. It is thought to be responsible for the inhibitory activity of pepstatin because it mimics the tetrahedral transition state of peptide catalysis.

Amfenac, also known as 2-amino-3-benzoylbenzeneacetic acid, is a nonsteroidal anti-inflammatory drug (NSAID) with acetic acid moiety.

Picamilon (also known as '''N-nicotinoyl-GABA, pycamilon, and pikamilon''') is a drug formed by a synthetic combination of niacin and γ-aminobutyric acid (GABA). It was developed in the Soviet Union in 1969 and further studied in both Russia and Japan as a prodrug of GABA.

Gabaculine is a naturally occurring neurotoxin first isolated from the bacteria Streptomyces toyacaensis, which acts as a potent and irreversible GABA transaminase inhibitor, and also a GABA reuptake inhibitor. Gabaculine is also known as 3-amino-2,3-dihydrobenzoic acid hydrochloride and 5-amino cyclohexa-1,3 dienyl carboxylic acid. Gabaculine increased GABA levels in the brain and had an effect on convulsivity in mice.

Isoglutamine or α-glutamine is a gamma amino acid derived from glutamic acid by substituting the carboxyl group in position 1 with an amide group. This is in contrast to the proteinogenic amino acid glutamine, which is the 5-amide of glutamic acid.

chemical compound

Atagabalin (, ; developmental code name PD-0200390) is a drug developed by Pfizer and related to gabapentin, which similarly binds to the α2δ calcium channels (1 and 2). It was under development as a treatment for insomnia, but was discontinued following unsatisfactory trial results. The drug reached phase 2 clinical trials for this indication prior to the discontinuation of its development.

chemical compound

Mirogabalin (brand name Tarlige; developmental code name DS-5565) is a gabapentinoid medication developed by Daiichi Sankyo. Gabapentin and pregabalin are also members of this class. As a gabapentinoid, mirogabalin binds to the α2δ subunit of voltage-gated calcium channel (1 and 2), but with significantly higher potency than pregabalin. It has shown promising results in Phase II clinical trials for the treatment of diabetic peripheral neuropathic pain.

GABA agonist

Pivagabine (INN; brand name Tonerg), also known as '''N-pivaloyl-γ-aminobutyric acid or N-pivaloyl-GABA''', is an antidepressant and anxiolytic drug which was introduced in Italy in 1997 for the treatment of depressive and maladaptive syndromes. But it was discontinued in Italy (according to Martindale). Originally believed to function as a prodrug to GABA, pivagabine is now believed to act somehow via modulation of corticotropin-releasing factor (CRF).
