NQTrp
目录号 : KCM12178 CAS No. : 185351-19-3 纯度 : ≥98%
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.

生物活性

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.

  • 1.

    请依序添加每种溶剂:10% DMSO → 40% PEG300 → 5% Tween-80 → 45% saline

    Solubility: ≥ 2.08 mg/mL (5.77 mM); Clear solution

    此方案可获得 ≥ 2.08 mg/mL (5.77 mM,饱和度未知) 的澄清溶液。

    以 1 mL 工作液为例,取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;向上述体系中加入50 μL Tween-80,混合均匀;然后继续加入 450 μL生理盐水定容至 1 mL。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
