Abstract<\/h2>\n\n\n\n

Parkinson\u2019s disease (PD) is a neurodegenerative disorder characterized by the loss of dopaminergic neurons in the substantia nigra<\/em>, as well as the accumulation of intra-neuronal proteinaceous inclusions known as Lewy bodies and Lewy neurites. The major protein component of Lewy inclusions is the intrinsically disordered protein \u03b1-Synuclein (\u03b1-Syn), which can adopt diverse amyloid structures. Different conformational strains of \u03b1-Syn have been proposed to be related to the onset of distinct synucleinopathies; however, how specific amyloid fibrils cause distinctive pathological traits is not clear. Here, we generated three different \u03b1-Syn amyloid conformations at different pH and salt concentrations and analyzed the activity of SynuClean-D (SC-D), a small aromatic molecule, on these strains. We show that incubation of \u03b1-Syn with SC-D reduced the formation of aggregates and the seeded polymerization of \u03b1-Syn in all cases. Moreover, we found that SC-D exhibited a general fibril disaggregation activity. Finally, we demonstrate that treatment with SC-D also reduced strain-specific intracellular accumulation of phosphorylated \u03b1-Syn inclusions. Taken together, we conclude that SC-D may be a promising hit compound to inhibit polymorphic \u03b1-Syn aggregation.<\/p>\n\n\n\n
