The present invention covers radiosensitizers containing as an active ingredient halogenated derivatives of boronated porphyrins containing multiple carborane cages having the structure ##STR1## which selectively accumulate in neoplastic tissue within the irradiation volume and thus can be used in cancer therapies including, but not limited to, boron neutron--capture therapy and photodynamic therapy. The present invention also covers methods for using these radiosensitizers in tumor imaging and cancer treatment.
This invention was made with U.S. government support under U.S. Department of Energy Contract No. DE-AC02-98CH10886 with Brookhaven National Laboratory. The U.S. Government has certain rights in the invention.
