    Inhibition of alpha-synuclein seeded fibril formation and toxicity by herbal medicinal extracts. by Ardah, Mustafa T

    Published 2020
    “…In order to investigate the inhibitory mechanisms of these two compounds towards fibril formation, we demonstrated that salvianolic acid B binds predominantly to monomers, while dihydromyricetin binds to oligomeric species and to a lower extent to monomers. Remarkably, these two compounds stabilized the soluble non-toxic oligomers lacking β-sheet content after subjecting them to proteinase K digestion. …”
