And, the most amazing thing about it is that the results usually represent a permanent fix

As illustrated in Scheme 5, the complex cellular metabolism of arsenic is characterized by the reduction of As(V) to As(III) through an even-electron redox cycle which involves as the counterpart a bio-thiol such as glutathione and the formation of a tris- glutathionyl-As(III) species

This blocks DNA replication, leading to inhibited cell division and proliferation, and ultimately apoptosis
