NQTrp is an inhibitor of Alzheimer’s disease-associated amyloid β (Aβ) oligomerization and fibrillization (IC = 50 nM for formation of fibrils from Aβ1-42). It has been shown to reduce the cytotoxic effect of Aβ oligomers in a cultured neuronal cell line.
NQTrp , an aromatic naphthoquinone-tryptophan hybrid molecule, an inhibitor of the aggregation of the tau protein with generic anti-amyloidogenic effects. NQTrp inhibits the in vitro aggregation of hexapeptide (41GCWMLY46 within the N-terminus of γD-crystallin) as well as full-length γD-crystallin.
体外研究
In TEM analysis, GDC6 peptide fibrils (50 μM) in the presence of NQTrp 5:1, 1:1, 1:5 ratio (GDC6: NQTrp). NQTrp effectively inhibits the fibrillation of the GDC6 peptide (50 μM) in a dose-dependent manner and prevents the formation of elongated amyloid fibrils.
NQTrp has no toxic effect toward retinal cell culture and reduces the cytotoxicity induced by aggregates of the hexapeptide(IC50=70 μM) in ARPE-19 cells.
