α-synuclein

α-Syn

α-Synuclein is an abundant neuronal protein that is highly enriched in presynaptic nerve terminals. α-synuclein regulates synaptic vesicle trafficking and subsequent neurotransmitter release. Genetics and neuropathology studies link α-synuclein to Parkinson's disease (PD) and other neurodegenerative disorders. Accumulation of misfolded oligomers and larger aggregates of α-synuclein defines multiple neurodegenerative diseases called synucleinopathies, but the mechanisms by which α-synuclein acts in neurodegeneration are unknown.

Scyllo-Inositol can selectively bind to and stabilize non-toxic oligomers, preventing them from converting into toxic fibers, exerting protein homeostasis regulation and neuroprotective activity. Scyllo-Inositol binds to the hydrophobic region of pathogenic proteins, inhibits protein aggregation, and promotes lysosome- and proteasome-mediated degradation pathways, thereby reducing neurotoxicity. Scyllo-Inositol can be used in the study of neurodegenerative diseases such as Parkinson's disease, Alzheimer's disease, and Huntington's disease.
