NQTrp 是芳香萘醌-色氨酸杂交分子，可以抑制 tau 蛋白的聚集，具有抗淀粉样蛋白活性。NQTrp 对六肽 (41GCWMLY46，γD-crystallin 的 N 端)和全长 γD-crystallin 的体外聚集有抑制作用。

NQTrp is 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. 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. In TEM analysis, GDC6 peptide fibrils (50 μM) in the presence of NQTrp 5:1, 1:1, 1:5 ratio (GDC6: NQTrp)[1].
