Abstract:It has been indicated that there are a large number of natural active compounds generating the radiosensitizing effect on tumor. According to diverse molecular mechanism,these compoundsmay enhance the radiotherapeutic efficacy via enhancing the radiosensitivity of tumor. Studying the radiosensitization mechanism and classifying the natural compounds with the potentiality of development into clinical radiosensitizers can provide certain ideas for further research and development of natural radiosensitizers.
