Biological target:
GPI-1485 (GM1485), a nonimmunosuppressive immunophilin ligand, promotes neurofunctional improvement and neural regeneration following stroke.
In vitro activity:
Additionally, GM1485-treated fibroblasts subjected to oxidative stress were reprogrammed to a stem-cell-like phenotype and were able to differentiate down a neuronal lineage.
Reference: J Neurosci Res. 2012 Jul;90(7):1413-23. https://pubmed.ncbi.nlm.nih.gov/22431363/
In vivo activity:
GM1485-treated rats demonstrated improved neurological function as well as increased Sox2(+) cells in the ipsilateral SVZ and striatum relative to vehicle-treated rats.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
