Tetrahydroxyquinone monohydrate (Tetrahydroxy-1,4-benzoquinone monohydrate)，一种抗白内障剂，是一种具有氧化还原活性的苯醌。Tetrahydroxyquinone monohydrate 可与半醌自由基一起参与氧化还原循环，导致活性氧 (ROS) 形成。

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

Solid

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). has not independently confirmed the accuracy of these me
