VitK3, VitK3,menadione: Click to Expand ⟱
Features:
Menadione (2-methyl-1,4-naphthoquinone, also termed vitamin K3)
Menadione-induced ROS generation is concentration-dependent and high concentrations trigger cell death.
Clinical trials conducted on patients with prostate cancer showed that ascorbic acid-menadione produced an immediate drop in tumor cell numbers through a mechanism named autoschizis.
Menadione (Vitamin K3) is a synthetic naphthoquinone compound. It is not used as a nutritional vitamin supplement in humans due to toxicity risk (particularly hemolysis and hepatotoxicity). Historically used in animal feed.
Mechanistically, menadione functions primarily as a redox-active quinone, capable of:
-Undergoing redox cycling
-Generating reactive oxygen species (ROS)
-Inducing oxidative stress
-Interacting with glutathione (GSH) systems
-Modulating mitochondrial function
It has been investigated in oncology research largely due to its pro-oxidant cytotoxic properties, not classical vitamin K–dependent clotting roles.

Rank Pathway / Axis Cancer / Tumor Context Normal Tissue Context TSF Primary Effect Notes / Interpretation
1 Redox cycling (quinone-mediated ROS generation) ROS ↑; oxidative stress ↑; apoptosis ↑ (dose-dependent) Oxidative injury risk ↑ (hemolysis, hepatotoxicity) P, R Primary cytotoxic mechanism Menadione undergoes one-electron redox cycling, generating superoxide and hydrogen peroxide; not selective for tumor cells.
2 Glutathione (GSH) depletion GSH ↓; redox buffering capacity ↓ Red cell vulnerability ↑ P, R Redox destabilization Conjugation and oxidative cycling consume GSH, amplifying oxidative stress.
3 Mitochondrial dysfunction ΔΨm ↓; ATP ↓; apoptosis signaling ↑ Energy stress in normal cells possible R, G Mitochondria-mediated apoptosis ROS and redox imbalance disrupt mitochondrial membrane potential.
4 DNA damage (oxidative) DNA strand breaks ↑ (reported) Genotoxic risk ↑ R, G Genome instability Often secondary to ROS accumulation rather than direct DNA intercalation.
5 Synergy with ascorbate (Vitamin C) Redox cycling ↑; cytotoxicity ↑ (reported in vitro) Systemic oxidative injury risk ↑ P, R Redox amplification Menadione can undergo redox cycling with ascorbate, increasing ROS production; largely preclinical data.
6 Topoisomerase interference (reported) Topo inhibition (context-dependent) ↔ R Secondary mechanism Some studies report interference with topoisomerase activity, but this is not the dominant mechanism.
7 Hemolysis risk (G6PD vulnerability) — Red blood cell destruction risk ↑ R Major toxicity constraint Menadione can cause hemolytic anemia, especially in G6PD deficiency.
8 Hepatotoxicity — Liver injury risk ↑ G Clinical toxicity constraint Historical reason for discontinuation as a human supplement.
9 Vitamin K–dependent clotting pathway Minimal physiologic role in humans Not equivalent to K1/K2 — Classification clarification Menadione is a synthetic precursor; does not function identically to phylloquinone (K1) or menaquinones (K2).

Time-Scale Flag (TSF): P / R / G

  • P: 0–30 min (rapid redox cycling and ROS generation)
  • R: 30 min–3 hr (mitochondrial dysfunction, DNA damage signaling)
  • G: >3 hr (apoptosis, tissue-level toxicity outcomes)
