Abstract: The present technology provides compounds as well as compositions including such compounds useful for the treatment of cancers where the compounds are represented by the following formula or a pharmaceutically acceptable salt thereof, wherein M is an alpha-emitting radionuclide.

Abstract: Metal-chelating compositions having the structure (1a) wherein: R1, R2, R3, and R4 are independently selected from the following groups: (i) hydrogen atom, (ii) hydrocarbon groups (R) containing 1-12 carbon atoms; (iii) halogen atoms; (iv) —P(R5) (?O)OH groups; (v) —C(?O)OH groups; (vi) —S(?O)2OH groups; and (vii) —OH groups, wherein R5 is selected from hydrocarbon groups (R) and —OH; R1 and R2 may optionally interconnect to form Ring A fused to the ring on which R1 and R2 are present; R3 and R4 may optionally interconnect to form Ring B fused to the ring on which R3 and R4 are present; wherein Ring A and Ring B are optionally and independently substituted with one or more of groups (ii)-(vii). Methods of using the above-described compositions for chelating metal ions having an atomic number of at least 56 (e.g., Ba or Ra) are also described.

Abstract: Among the various aspects of the present disclosure is the provision of compositions of isotope-ligand complexes, methods of use thereof, and methods of chelating isotopes. The present disclosure also provides for methods for modulating ion channel transportation of radiopharmaceuticals. For example, the inhibition of radiopharmaceutical transport comprises administering an ion channel transport modulating or inhibiting agent (e.g., a calcium channel inhibitor) in an amount effective to inhibit gastrointestinal uptake.
