Ascorbate and menadione (Apatone) in a ratio of 100:1 kills tumor cells by autoschizis.

At concentrations of 100 microM and higher, menadione depleted the cells of both GSH and ascorbate , and ascorbate loading partially prevented the decrease in GSH due to menadione.
Menadione caused intracellular oxidation of dihydrofluorescein, which required the presence of D-glucose in the incubation medium, and was inhibited by intracellular ascorbate and desferrioxamine.
Menadione increased L-arginine uptake by the cells, but inhibited endothelial nitric oxide synthase, an effect that was prevented by acute loading with ascorbate.

After administration of menadione and ascorbate , we found a 21-fold increase of the recovery rate relative to the pretherapy value, to within 56% of the recovery rate of the young female control.

Finally, while H2O2, when administered as a bolus, strongly enhances a constitutive basal NF-κB activity in TLT cells, their incubation in the presence of ascorbate and menadione results in a total abolition of such a constitutive activity.

This fraction displays low-potential properties, as it can be also oxidised by menadione in the presence of 5 mM ascorbate.
