Smart Supplyment Nsi-189/Nsi189 Powder for Anti-Depression 1270138-40-3

NSi-189 powder is an experimental drug currently being developed and studied by Neuralstem Inc., a biotechnology company that commercially produces neural stem cells for therapy.[3] The research and development of NSI-189 began in the 1990s, during the years of Bill Clinton's presidency.

The Clinton administration contracted Neuralstem to research the possibilities of creating a "super soldier," one that was able to stay awake and alert for extended periods of time.[4] The researchers at Neuralstem recognized that a drug targeting the hippocampus could possibly alleviate the effects of sleep deprivation and exhaustion, and set out to find a drug that could induce neurogenesis. Neuralstem, finding their prospects to be promising, continued research in this vein even after the government program was canceled.

This preliminary research would eventually result in the drug NSI-189. Clinical research on NSI-189 has been in the works since 2011, and a phase 1b trial was completed in July of 2014.[5] Clinical phase 1 trials typically focus on finding the correct dosage range of the drug, which has been placed around 40 to 80 mg per day in the treatment of Major Depressive Disorder (MDD) and cognitive decline.

NSI-189 Background
NSI-189 is a benzylphiperizine-aminiopyridine, nootropic and neurogenic research chemical created by Neuralstem, Inc. that was derived from pyrazine and nicotinamide. Studies have shown that it stimulates neurogenesis of human hippocampus-derived neural stem cells in vivo and vitro. In healthy adult mice, NSI-189 has been shown to increase the hippocampal volume by 20% and reverse behavioral symptoms in mouse depression models, meaning at the source it could address depression . The hippocampus is responsible for spatial navigation, along with the consolidation of information from short-term memory to long-term memory.

The chemical entity stimulates new neuron growth in the hippocampus, which is an area of the brain that is believed to be contributory in conditions such as post-traumatic stress disorder (PTSD), Alzheimer's disease, and major depressive disorder (MDD).

NSI-189's Method of Action
Although it has been demonstrated in rats and chimps, the suggestion that having too small of a hippocampus causes depression and other diseases in humans is still technically just a theory. NSI-189 increases hippocampal volume in adult mice by 20%, a region of the brain that is one of the first to suffer damage resulting in memory loss, disorientation, encephalitis, and hypoxia from disease's such as Alzheimer's .

NSI-189 Benefits
Tests have shown that NSI-189 significantly improved behavioral responses that are associated with depression . In humans it may counter hippocampal atrophy which is seen in disorders such as MDD, reversing their symptoms. A phase 1B randomized, double-blind, placebo-controlled, multiple-dose escalation study conducted over a 28 day period showed behavioral efficacy in 24 patients who were orally administered NSI-189 . The efficacy measurements showed a clinically meaningful reduction in cognitive and depressive symptoms across all measures, and appeared to persist over time during follow up for the efficacy assessments which included the Clinical Global Impression - Improvement (CGI-I), Montgomery-Aserb Depression Rating Scale (MADRS), Cognitive and Physical Functioning Questionnaire (CPFQ, and the Symptoms of Depression Questionnaire (SDQ) .

Dosing NSI-189
Phase 1A tested escalating doses of the neurogenic compound NSI-189 in healthy patients, 1B tested the safety of escalating doses in 24 depressed patients over the course of 28 days . During phase 1B patients were administered 40 mg per day, and 80 mg per day, and at the highest dose 120 mg per day. No serious adverse events occurred during the time of the study and the drug was well tolerated. Reduction in cognitive and depressive symptoms were observed across all measures for the two lower doses 40 mg/day and 80 mg/day but not for the highest dose 120 mg/day.
