[About the "double" radioprotecting mechanism of some sulfur-containing substances]
Abstract:
The hypothesis about the double-acting mechanism of some radioprotectors during the irradiation of the DNA solutions is expressed in literature: the water radicals interception and the formation up to the irradiation of the additional intermolecular bonds "protector-DNA" (stabilization of the double helix). The realization conditions of this hypothesis were obtained by the molecular mechanics methods and the free radical mechanism appearance of the intrastrand cross-links "protector-DNA" during the irradiation of the polymer is given.
