N-(1,4-Dihydro-1,4-dioxo-2-naphthalenyl)-L-tryptophan Chemical Properties,Usage,Production

Description

NQTrp is an inhibitor of Alzheimer’s disease-associated amyloid β (Aβ) oligomerization and fibrillization (IC50 = 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.

Uses

NQTrp is a inhibitor of Aβ1-42 aggregation, altering Aβ self-assembly and reducing toxicity.
