Radiation Countermeasures: Current Status
Keywords: Ionizing radiation, Protectors, Mitigators, Therapeutics, Herbal, HDAC inhibitors
AbstractDeleterious effects of ionising radiation leading to significant morbidity and mortality have been studied elaborately. A range of synthetic, semisynthetic and herbal compounds have been screened as radiation countermeasure agents and a number of promising radiation countermeasure agents are under development. Amifostin is the only drug which has been approved by the United State Food and Drug Administration (US-FDA), but that too for use in a defined population under strict medical supervision. Granulocyte Colony Stimulating Factor/filgrastim, γ-tocotrienol, genistein are at an advanced stage of development and are tested on higher animal models as per required norms of FDA. Herbal compounds are also considered very safe and of high value as radiation countermeasure agents owing to various properties like antioxidant, immunomodulation activity etc. Histone deacetylase inhibitors such as Trichostatin A, Diallyl sulphide, Sulforaphane are being viewed as very promising radiomitigating agents by our laboratory and active research in the same direction is going on. Infusion of hematopoietic stem cells and growth factors are in practice as potent therapeutics. This review gives an overview on various radioprotectors, radiomitigators and therapeutic agents either available or under development currently.
