| titleOfInvention | Protein scaffolds for targeted delivery of toxic iron to cancer cells |
| abstract | Described herein are modifications and adaptations of iron storage proteins for a novel photo-initiated approach to cancer therapy whereby cells are killed via production of iron-generated hydroxyl radicals. The iron is photo-released from a protein scaffold that includes tumor-targeting peptides and/or proteins fused to the exterior surface of the protein scaffold. One or more photosensitizers are coupled to the protein shell. The multiple tumor-targeting peptides and/or proteins will bind to specific hyperexpressed receptors on the cancer cells. After binding of the photosensitizer-iron-loaded protein to the cancer cells, photochemical excitation of the photosensitizers with tissue-penetrating near-infrared light triggers release of “free” ferrous iron, which in oxic or mildly hypoxic intracellular environments generates toxic hydroxyl radicals via Fenton chemistry. This light-triggered release of “free” iron overwhelms the cancer cells' defenses against free radicals. The combination of tumor-targeting peptides and photo-triggered release of iron ensures that non-cancerous cells are not bombarded with iron. |
