LY-503430 produces both nootropic and neuroprotective effects, reducing brain damage caused by 6-hydroxydopamine or MPTP and also increasing levels of the neurotrophic factor BDNF in the brain, particularly in the substantia nigra, hippocampus, and striatum.^[2][3] It is orally active and the main application it is currently being developed for is treatment of Parkinson's disease, although it has also been proposed to be useful in the treatment of Alzheimer's disease, depression, and schizophrenia.^[4][5]
