CX-614 is an ampakine drug developed by Cortex Pharmaceuticals. It has been investigated for its effect on AMPA receptors.[1]

CX-614 produces rapid increases in release of the neurotrophic factor BDNF[2] and may have applications in the treatment of neurodegenerative diseases such as Alzheimer's disease. It has also been proposed as a treatment for conditions such as depression and schizophrenia,[3][4] but produces receptor downregulation following chronic administration, which might limit the potential for extended use.[5][6] CX-614 has also been shown to reduce the behavioural effects of methamphetamine in mice, and may have application in the treatment of stimulant abuse.[7]
