- Mechanism of action
Caprospinol cleared beta-amyloid plaque formation and restored memory capacity in-vivo; confirming in-vitro studies showing Caprospinol binds ß-amyloid directly and inhibits the formation of neurotoxic amyloid-derived diffusible ligands (ADDLs) by forming stable heavy complexes with the peptide. In addition, the studies demonstrated Caprospinol protects mitochondria function, thus protecting cell viability and decreased cell death.
