GABA Receptor

Gamma-aminobutyric acid Receptor; γ-Aminobutyric acid Receptor

GABA receptors are a class of receptors that respond to the neurotransmitter gamma-aminobutyric acid (GABA), the chief inhibitory neurotransmitter in the vertebrate central nervous system. There are two classes of GABA receptors: GABAA and GABAB. GABAA receptors are ligand-gated ion channels (also known as ionotropic receptors), whereas GABAB receptors are G protein-coupled receptors (also known asmetabotropic receptors). It has long been recognized that the fast response of neurons to GABA that is blocked by bicuculline and picrotoxin is due to direct activation of an anion channel. This channel was subsequently termed the GABAA receptor. Fast-responding GABA receptors are members of family of Cys-loop ligand-gated ion channels. A slow response to GABA is mediated by GABAB receptors, originally defined on the basis of pharmacological properties.

    Creatinine-13C
    Modulator 99.93%
    Creatinine-13C is the 13C-labeled Creatinine. Creatinine (NSC13123) is an orally active, blood-brain barrier-permeable modulator of GABAA and NMDA receptors, with activities of antioxidation and metabolic regulation. Creatinine is generated via non-enzymatic conversion of creatine and phosphocreatine in muscle. Creatinine serum levels correlate with muscle mass, glomerular filtration rate, and extrarenal clearance, serving as an evaluation biomarker for renal function, muscle mass, and clinical outcomes, and used for perioperative renal risk assessment. In addition, Creatinine can induce specific Cryptococcus species to produce creatinine deiminase and act as their nitrogen source, while it can be secreted via renal tubules. Creatinine is widely used in research related to various diseases such as neurodegenerative diseases, psychiatric disorders, acute kidney injury, chronic kidney disease, and renal failure.

    Dehydroepiandrosterone sulfate sodium salt-d6 (DHEA sulfate sodium salt-d6; Prasterone sulfate sodium salt-d6) is the deuterium labeled Dehydroepiandrosterone sulfate sodium salt (HY-B0765). Dehydroepiandrosterone sulfate (DHEA sulfate; Prasterone sulfate) sodium salt is a neurosteroid and the main secretion product of the adrenal gland. Dehydroepiandrosterone sulfate sodium salt has both non-competitive antagonist activity of GABAA receptor and agonist activity of σ1 receptor. Dehydroepiandrosterone sulfate sodium salt can partially penetrate the blood-brain barrier, inhibit GABAA receptor-mediated chloride influx, enhance NMDA receptor activity through σ1 receptors, exert anti-inflammatory, anti-glucocorticoid and antidepressant effects, and increase convulsive sensitivity. Dehydroepiandrosterone sulfate sodium salt participates in neuroprotection, neurite growth regulation and catecholamine secretion regulation, and can be used in the study of depression, post-traumatic stress disorder (PTSD), Alzheimer's disease, etc. Dehydroepiandrosterone sulfate sodium salt may also be a biomarker for cardiovascular disease mortality, and its concentration is independently and negatively correlated with mortality.
