Vitamin K3 is a synthetic naphthoquinone without the isoprenoid side chain and biological activity, but can be converted to active vitamin K2, menaquinone, after alkylation in vivo. It induces apoptosis in various cultured cells including leukemia cells. It has been shown that vitamin K exerts anti-tumor activity by inhibiting cdk1 activity and over expressing the c-myc gene to induce apoptotic cell death. Another hypothesis based on investigation done on the mode of actions of vitamin K suggests that VK3 induces apoptosis by promoting the generation of intracellular reactive oxygen intermediates and Fas/APO-1 expression.
