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.

    Phenelzine-d5 sulfate
    		Inhibitor 99.97%
    Phenelzine-d5 sulfate is the deuterium labeled Phenelzine sulfate (HY-B1018A). Phenelzine sulfate, an antidepressant agent, is an irreversible and orally active monoamine oxidase (MAO-A and MAO-B) inhibitor. Phenelzine sulfate inhibits GABA transaminase and primary amine oxidase (PrAO), and sequester reactive aldehydes. Phenelzine sulfate also inhibits LSD1 (Ki: 5.6 μM) and suppresses oxidative stress and lipogenesis. Phenelzine sulfate elevates neurotransmitters (serotonin, norepinephrine, dopamine). Phenelzine sulfate is studied in neurological, metabolic and cancer diseases for depression and anxiety disorders, stroke, spinal cord injury, traumatic brain injury, multiple sclerosis, Parkinson’s disease, Alzheimer’s disease, inflammatory pain, obesity and prostate cancer.
