Description: LY-404187 is an ampakine, AMPA receptor potentiator. LY-404187 has been demonstrated to enhance cognitive function in animal studies, and has also shown effects suggesting antidepressant action as well as having possible application in the treatment of schizophrenia, Parkinson's disease and ADHD. These effects appear to be mediated through multiple mechanisms of action secondary to AMPA receptor potentiation, with a prominent effect seen in research being increased levels of BDNF in the brain.

Product Data:
Biological target: LY-404187 is a potent, selective and centrally active positive allosteric modulator of AMPA receptors, with the EC50s of 5.65, 0.15, 1.44, 1.66 and 0.21 µM for GluR1i, GluR2i, GluR2o, GluR3i and GluR4i.
In vitro activity: Using a strategy of combined morphological and biochemical analyses, this study investigated the effect of the AMPA receptor potentiator LY404187 on neurite growth in the SH-SY5Y human neuroblastoma cell line. LY404187 (0.1-10 microM) increased average neurite length and neurofilament expression when co-administered with s-AMPA. Antibody sequestration of BDNF attenuated neurite growth following AMPA receptor potentiator administration, suggesting that LY404187 increases neurite length in vitro by a BDNF mediated mechanism. Reference: Neuropharmacology. 2007 Feb;52(2):590-7. https://pubmed.ncbi.nlm.nih.gov/17101156/
In vivo activity: The present study reports that the potent and selective AMPA receptor potentiator, R,S-N-2-(4-(4-Cyanophenyl)phenyl)propyl 2-propanesulfonamide (LY404187), provides both functional, neurochemical and histological protection against unilateral infusion of 6-hydroxydopamine into the substantia nigra or striatum of rats. In addition, LY404187 provided a dose-dependent increase in growth-associated protein-43 expression in the striatum.
