Chromosome abnormalities frequently are seen following radiation treatment and are thought to be a major factor in radiation-induced cell death.[5] Amifostine provides intercellular thiols that modify radiation and chemotherapy damage by chemically restoring or reducing free radical damage to target molecules.[2] Reduction of free radical damage is one of the mechanisms by which radioprotective drugs are thought to work.[5] Amifostine can protect healthy cells from both high and low energy radiation, but only when the drug is taken into the cell's plasma membrane.
