WebNov 7, 2024 · Cholesterol (CHOL) is an indispensable component of liposomes. Incorporation of 7-dehydrocholesterol (7-DHC) instead of CHOL can efficiently enhance the anticancer activity of photosensitizer-encapsulated liposomes upon irradiation, yielding an IC 50 value about half of that of CHOL-based controls. The photo-oxidation of 7-DHC into … 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.
