Agents that Provide Protection against Radiation

Radioprotective Agent Mechanism Reference(s)
Free radical scavengers Amifostine (WR2721/WR1065) Thiol- and sulfhydryl- containing, is activated by alkaline phosphatases only in normal tissues (13)
MnSOD Superoxide scavenging, radioprotective in normal tissues (17)
(37)
Nitroxides (TEMPOL) Superoxide Dismutase Mimetic (19)
Protective only in normal tissues (77)
Vitamins A, C, E Antioxidants (78)
(79)
Melatonin Scavenges hydroxl radicals, increases the activity of intracellular antioxidants, decreases the activity of NOS (21)
NOS inhibitors AMT, L-NAME, 7-nitroindazole Prevent overproduction of NO and ONO2 (18)
Anti-inflammatory agents Resveratrol, Palifermin, Benzydamine and others Anti-inflammatory properties, regulate intrinsic cytoprotective mechanisms, stimulate or inhibit cellular proliferation and differentiation (24)
(13)
Immunomodulators Gamma-interferon, RT-1, polysaccharides, propolis Immune stimulation, production of cytokines (27)
(78)
