Synucleozid (0.25-1 μM; 24 hours) abrogates cytotoxicity induced by α-synuclein preformed fibrils, which act as seeds and recruit endogenous α-synuclein to aggregate.
Synucleozid (0-1 μM; 24 hours) binds to the A bulge near the base of the IRE hairpin, reduced levels of α-synuclein in a dose-dependent manner with an IC50 of 500 nM, and inhibits α-synuclein protein expression in SH-SY5Y neuroblastoma cells.
Synucleozid (100 nM-100 μM; 24 hours) binds to 2-AP-labeled and native IRE RNA with similar affinities. It decreases 2-AP emission with an EC50 value of 2.7 μM, recovery of 2-AP emissions is observed as a function of unlabeled SNCA IRE RNA (RNA-0) concentration, affording a competitive Kd of 1.5 μM.
Synucleozid (0.25-1 μM; 24 hours) decreases α-synuclein and other proteins that have IREs in their mRNA’s UTR including APP, PrP, Ferritin and TfR as a dose-dependent mannner. All panels is completed in SH-SY5Y cells, except for PrP protein which is assessed in Neuro-2A cells.
