Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/26643541 | http://www.neuralstem.com/docs/5Nov14CNSSummitFinal.pdf | http://www.neuralstem.com/pdf/NSI189-Radiation-induced-2016-Hawaii-Poster.pdf

NSI-189 is a novel oral drug which was developed by Neuralstem for the treatment of cognitive disorders. Now the drug is being tested in phase II of clinical trials in patients suffering from major depressive disorder. The mechanism of NSI-189 action is explained by its ability to stimulate the generation of new neurons in the hippocampus, however the exact target molecule is still unknown.
