生物活性

Tetrahydroxyquinone (Tetrahydroxy-1,4-benzoquinone), a primitive anticataract agent, is a redox active benzoquinone. Tetrahydroxyquinone can take part in a redox cycle with semiquinone radicals, leading to the formation of reactive oxygen species (ROS).

体外研究

Tetrahydroxyquinone (100-500 μM; 24 hours; HL60 cells) treatment shows cytotoxic for HL60 leukaemia cells by total protein content (IC50 of 20 µM), phosphatase activity (IC50 of 40 µM), or by MTT assay (IC50 of 45 µM). Tetrahydroxyquinone is an efficient inducer of ROS production in HL60 leukaemia cells.
Tetrahydroxyquinone efficiently activates caspase 3 in concentration in excess of 25 µM, stimulates DNA fragmentation at the same concentration and provoke phosphatidylserine exposure.
Tetrahydroxyquinone induces the release of cytochrome c from the mitochondria at concentration as low as 25 µM. Tetrahydroxyquinone treatment also causes increase of phosphorylation of Ser473 in protein kinase B (the Bad kinase for Ser112).

  • 1.

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

    Solubility: ≥ 2.5 mg/mL (14.53 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (14.53 mM,饱和度未知) 的澄清溶液。

    以 1 mL 工作液为例,取 100 μL 25.0 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。

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
