Org 26576 is an ampakine drug originally developed by Cortex Pharmaceuticals and then licensed to Organon International for development. In animal studies it has been shown to effectively potentiate AMPA receptor function, leading to increased BDNF release and enhanced neuronal differentiation and survival, as well as producing nootropic effects in standardised assays.[1][2][3][4][5][6]
