LY-503,430 is an ampakine drug developed by Eli Lilly. [O'Neill MJ, Murray TK, Clay MP, Lindstrom T, Yang CR, Nisenbaum ES. LY503430: pharmacology, pharmacokinetics, and effects in rodent models of Parkinson's disease. "CNS Drug Reviews". 2005 Spring;11(1):77-96. [ PMID 15867954] ]

LY-503,430 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. [Murray TK, Whalley K, Robinson CS, Ward MA, Hicks CA, Lodge D, Vandergriff JL, Baumbarger P, Siuda E, Gates M, Ogden AM, Skolnick P, Zimmerman DM, Nisenbaum ES, Bleakman D, O'Neill MJ. LY503430, a novel alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptor potentiator with functional, neuroprotective and neurotrophic effects in rodent models of Parkinson's disease. "Journal of Pharmacology and Experimental Therapeutics". 2003 Aug;306(2):752-62. [ PMID 12730350] ] [Ryder JW, Falcone JF, Manro JR, Svensson KA, Merchant KM.

"Journal of Pharmacology and Experimental Therapeutics". 2006 Oct;319(1):293-8. [ PMID 16803862] ] 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.
