Bioreductive drugs as post-irradiation sensitizers: comparison of dual function agents with SR 4233 and the mitomycin C analogue EO9

Int J Radiat Oncol Biol Phys. 1992;22(4):717-20. doi: 10.1016/0360-3016(92)90510-o.

Abstract

Various bioreductive drugs that are potent hypoxic cell cytotoxins can also function as effective potentiators of radiation action when administered in vivo post irradiation. There is evidence that a contributory mechanism to this potentiation is enhanced sensitivity to the bioreductive drugs exhibited by cells that are damaged sublethally by radiation.
