(99m)Tc Auger electrons for targeted tumour therapy: a review.
PURPOSE Targeted radiotherapy using Auger electrons presents multiple advantages and challenges. The advantageous characteristics of this type of radiotherapy can explain the growing interest in these specific electrons for cancer therapy. During the last decade, Technetium-99m ((99m)Tc) has been used as an imaging agent and only recently has it been analysed as a potential therapeutic agent. T...
متن کاملSb119-A potent Auger emitter for targeted radionuclide therapy.
Auger electron emitting radionuclides in cancer therapy offer the opportunity to deliver a high radiation dose to the tumor cells with high radiotoxicity while minimizing toxicity to normal tissue. We have in this study identified the Auger emitter Sb119 as a potent nuclide for targeted radionuclide therapy based on theoretical dosimetry calculations at a subcellular scale. From these calculati...
متن کاملMelanoma Therapy via Peptide-Targeted A-Radiation
Purpose:The therapeutic efficacy of a unique melanoma-targeting peptide conjugated with an in vivo generated a-particle-emitting radionuclide was evaluated in the B16/F1mouse melanoma animal model. a-Radiation is densely ionizing, resulting in high concentrations of destructive radicals and irreparable DNA double-strand breaks. This high linear energy transfer overcomes radiation-resistant tumo...
متن کاملSynergism of peptide receptor-targeted Auger electron radiation therapy with anti-angiogenic compounds in a mouse model of neuroendocrine tumors
BACKGROUND Neuroendocrine tumors are well vascularized and express specific cell surface markers, such as somatostatin receptors and the glucagon-like peptide-1 receptor (GLP-1R). Using the Rip1Tag2 transgenic mouse model of pancreatic neuroendocrine tumors (pNET), we have investigated the potential benefit of a combination of anti-angiogenic treatment with targeted internal radiotherapy. MET...
متن کاملEvaluation of Acridine Orange Derivatives as DNA-Targeted Radiopharmaceuticals for Auger Therapy: Influence of the Radionuclide and Distance to DNA
A new family of 99mTc(I)- tricarbonyl complexes and 125I-heteroaromatic compounds bearing an acridine orange (AO) DNA targeting unit was evaluated for Auger therapy. Characterization of the DNA interaction, performed with the non-radioactive Re and 127I congeners, confirmed that all compounds act as DNA intercalators. Both classes of compounds induce double strand breaks (DSB) in plasmid DNA bu...
