Vitamin K acts as a cofactor in normal blood coagulation from the post translation modification of a number of plasma proteins such as prothrombin. Vitamin K has been the focus of considerable research demonstrating an anticancer potential.However, yet the mechanisms of action remain unclear. A number mechanisms has been proposed and focused on the oxidative model which increased redox-cycling of menadione and the production of ROS surpasses the oxidative capacity of the cell, resulting in cell death.

由过去文献报告指出，Vitamin K也具有抗癌的效果，但作用机制不是完全清楚，目前了解依作用机制分成2种模式，一则是氧化模式，透过氧化还原的方式大量产生过氧化物，增加细胞氧化的负担而进一步造成细胞死亡，另一则是非氧化模式由从转录因子来探讨，Vitamin K会促进特定的转录因子表现进而调控细胞周期停滞及细胞凋亡。

人们普遍认为具有不变价态的第二主族元素（碱土金属 Mg》，Caf&，STz&和 B／离于）在通常条件下既没有氧化还原性，也没有催化活性，因而一般认为它们即没有基于氧化还原性的化学发光行为，也没有基于催化活性的化学发光行为。
