 Use of NQTrp


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[1].

 NQTrp Biological Activity

Description 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[1].

In Vitro 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[1]. 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[1].
