WebNov 18, 2024 · Modern photoactivated chemo- therapeutic (PACT) compounds follow this concept: the non-irradiated form of the metal–ligand (M–L) compound has no biological activity and low toxicity, while the irradiated form has high toxicity to cancer cells by interacting with DNA, lipids or proteins (see Figure 1B) . WebFor each indication of a photoactivated chemotherapy, we test for improvements in safety and efficacy against the repurposed drug in cells and animal models. As needed, we'll modify the formulation and correlate outcomes with fluorescent behavior in a dosimetry system to prepare a therapy that meets the FDA requirements for an IND.
