Effectiveness And Mechanism Of Action Of Modified Porphyrins For Photodynamic Therapy Of Triple Negative Breast Cancer Cells, Hannah Brandon
Honors Theses
Triple negative breast cancer (TNBC) is a particularly aggressive form of breast cancer that lacks the three molecules typically targeted for treatment. Standard treatment methods leave much to be desired--the rates of metastasis and recurrence are high and the prognosis for most patients with TNBC is poor. One potential treatment for TNBC is photodynamic therapy (PDT), which uses compounds called photosensitizers that are taken up by all tissues in the body. The tumor is exposed to light, activating the photosensitizer and creating reactive oxygen species that cause cell death. This method is relatively pain-free, effective, and does not harm cells …

Killing Cancer With Light, Kaitlyn Thomas
Honors Theses
Photodynamic therapy (PDT) is a relatively new treatment option in medicine including treating some types of cancers. PDT utilizes light to activate small molecules for treatment. Some of these molecules used as PDT agents are porphyrin derivatives. While PDT is currently being used in the fight against cancer, it has several limitations and is currently being used in conjunction with chemotherapy and/or radiation in order to be effective. This research focused on synthesizing a new zinc (II) porphyrin and incorporating a fluorescent sulfocycline and testing the compound on the MB 231 breast cancer cell line.
Once the metallated porphyrin was …
