Valerate sodium increases GABA levels, regulates epigenetics and alters gut microbiome function. Valerate sodium can be used in research related to excessive alcohol consumption.

alpha-Asarone (α-Asarone) is one of the main psychoactive compounds, and possesses an antidepressant-like activity in mice.

Flupirtine (D 9998) is an orally active, blood-brain barrier-crossing non-opioid analgesic and neuroprotective agent. Flupirtine is a neuronal potassium channel opener (Kv7 activator), a NMDA receptor antagonist and a GABA receptor activator. Flupirtine stabilizes blood-brain-barrier integrity, reduces oxidative stress and brain leukocyte infiltration, enhances angioneurogenesis, suppresses calcium influx, stabilizes neuronal resting membrane potential, and counteracts focal cerebral ischemia. Flupirtine exhibits analgesic, muscle relaxant properties, protects neurons from excitotoxic, ischemic, or cytokine-mediated death. Flupirtine functions as a non-opioid analgesic without antipyretic or antiphlogistic properties, shows no relevant affinity to opiate receptor. Flupirtine can be used for the research of focal cerebral ischemia, pain, Alzheimer’s disease, or multiple sclerosis.

Darigabat (PF-06372865) is an orally active, α2/α3/α5 subtype-selective GABA_A positive allosteric modulator (PAM). Darigabat is a high affinity ligand at GABA_A receptors containing α1/α2/α3/α5 subunits (K_is of 2.9 nM, 21 nM, 134 nM for α2, α1 PAM, α2 PAM, respectively), with low affinity for α4/α6 subunits. Darigabat can across the blood-brain barrier (BBB). Darigabat has anxiolytic activity and has the potential for epilepsy.

Emamectin Benzoate (MK-244) is an orally active nervoussystem toxicant by binding g-aminobutyric (GABA) receptor in insects. Emamectin Benzoate is one of semi-synthetic derivative of Avermectin (HY-15311) with a broadspectrum of insecticidal and acaricidal activity. Emamectin Benzoate induces ROS-mediated DNA damage and cell apoptosis. Emamectin Benzoate, a mixture of the natural Emamectin B1a benzoate and Emamectin B1b benzoate, has the main component of Emamectin B1a benzoate.

rac-BHFF is a potent and orally active allosteric enhancer of GABA_B receptor.

Kavain is a class of kavalactone isolated from Piper methysticum, which has anxiolytic properties in animals and humans. Kavain positively modulated γ-Aminobutyric acid type A (GABAA) receptor.

Humulone (α-Lupulic acid), a prenylated phloroglucinol derivative, is a potent cyclooxygenase-2 (COX-2) inhibitor. Humulone acts as a positive modulator of GABA_A receptor at low micromolar concentrations. Humulone is an inhibitor of bone resorption. Humulone possesses antioxidant, anti-angiogenic and apoptosis-inducing properties.

Nefiracetam is a cognition-enhancing agent. Nefiracetam is an activator of nAChR, N-methyl-D-aspartate receptor (NMDAR), mGluR5, PKC, gamma-aminobutyric acid (GABA), and N/L-type Ca²⁺ channels. Nefiracetam promotes neuroplasticity and enhances neuroprotection. Nefiracetam can be used in Alzheimer's disease, epilepsy, and cerebral ischemia research.

Etifoxine, a non-benzodiazepine GABAergic compound, is a positive allosteric modulator of α1β2γ2 and α1β3γ2 subunit-containing GABA_A receptors. Etifoxine reveals anxiolytic and anticonvulsant properties in rodents.

Methionine-d₃ is the deuterium labeled Methionine. Methionine (MRX-1024; D-Methionine) is an effective chemoprotective agent which can also inhibit the neuronal activity through GABAA receptor activation.

DS2 is a selective positive allosteric modulator of δ-GABA_A receptor. DS2 selectively potentiates GABA responses mediated by α4β3δ receptor. DS2 does not enhance activity at α4β3γ2 and α1β3γ2 receptors. DS2 relieves pain and has the potential for sleep disorders research.

DL-Menthol (Racementhol) is an orally active, GABA_aR positive allosteric modulator and UDP-glucuronosyltransferase (UGT) inhibitor that can cross the blood-brain barrier. DL-Menthol binds to GABA_AR and exhibits an allosteric activation effect, enhancing GABA-mediated chloride influx and inhibiting neuronal excitability. DL-Menthol can induce surgical anesthesia in fish and inhibit the metabolic detoxification of tobacco carcinogens by human liver and intestinal UGT enzymes, resulting in reduced NNAL-N-Gluc production.
