摘要: The aggregation of alpha-synuclein (alphaS) in the brain has been implicated as a critical step development Lewy body diseases (LBD) [Parkinson's disease (PD)/dementia with bodies (DLB)] and multiple system atrophy (MSA). involvement neuroinflammation microglial activation emphasized pathogenesis PD. Recent epidemiological studies have revealed that therapeutic use non-steroidal anti-inflammatory drugs (NSAIDs) reduces risk developing Here, we examined effects NSAIDs, such ibuprofen, aspirin, acetaminophen, meclofenamic acid sodium salt, sulindac sulfide, ketoprofen, flurbiprofen, diclofenac naproxen, indomethacin, on formation destabilization alphaS fibrils (falphaS) at pH 7.5 37 degrees C vitro, using fluorescence spectroscopy thioflavin S electron microscopy. All except for naproxen inhibited falphaS dose-dependent manner. Moreover, these molecules dose-dependently destabilized preformed falphaS. overall activity was order: ibuprofen approximately aspirin acetaminophen salt sulfide>ketoprofen flurbiprofen salt>naproxen indomethacin. These findings indicate NSAIDs could be key or preventive agents LBD MSA.
