  • Agmantine is a natural metabolite of the amino acid arginine. It is formed when arginine is decarboxylated by the enzyme arginine decarboxylase and is found naturally in ragweed pollen, ergot fungi, octopus muscle, herring sperm, sponges, and the mammalian brain. Agmatine is both an experimental and investigational drug. As an investigational drug, it is being studied in a non-blinded prospective case study in the United States looking at patients who have been diagnosed with small fiber peripheral neuropathy between the ages of 18 to 75 years. Up to now (July 2013), the results of this study have not yet been published. As an experimental drug, agmatine is being studied for several indications such as cardioprotection, diabetes, decreased kidney function, neuroprotection (stroke, severe CNS injuries, epilepsy, glaucoma, and neuropathic pain), and psychiatric conditions (depression, anxiety, schizophrenia, and cognition). The exact mechanism of action is still being investigated for all of the potential indications of agmatine. (en)

http://linked.open...mechanismOfAction
  • The exact mechanism of action is still being investigated for all of the potential indications of agmatine. Some of the biochemical mechanisms discovered so far concern agmatine's indication for diabetes, neuroprotection, and psychiatric conditions. In diabetes, agmatine produces hypoglycemia by increasing the release of insulin form pancreatic islet cells and increasing glucose uptake by the cells through increased endorphin release from the adrenal glands. Concerning neuroprotection, agmatine's effects are thought to involve modulation of receptors (NMDA, alpha 2, and imidazoline) and ion channels (ATP sensitive potassium channels and voltage-gated calcium channels) as well as blocking nitric oxide synthesis. Agmatine blocks nitric oxide synthesis by reducing the nitric oxide synthase -2 (NOS-2) protein in astroglial cells and macrophages. With respect to agmatine's benefit in psychiatric disorders, it is suggested that the mechanism involves neurotransmitter receptor modulation of the NMDA, alpha-2, serotonin, opioid, and imidazoline receptors. Specifically when agmatine binds to the imidazoline and alpha 2 receptors, it acts as a neurotransmitter and releases catecholamines from the adrenal gland. (en)
