Igmesine (JO-1,784) is a sigma receptor agonist (IC50 = 39 nM (rat brain)).[1][2] It has neuroprotective and antidepressant-like effects in animal studies,[3][4] as well as nootropic effects in models of age-related cognitive decline.[5] In two phase II clinical trials, igmesine was found to be effective in the treatment of depression and was as active as the comparator fluoxetine.[2] However, in a large phase III clinical trial, igmesine failed to show significant effectiveness for depression.[6] The drug has not been developed further.[7]
