Developing Novel Water-Soluble Porphyrins For Potential Use As Photosensitizers In Photodynamic Therapy, Kayla R. Whittington Apr 2022

Developing Novel Water-Soluble Porphyrins For Potential Use As Photosensitizers In Photodynamic Therapy, Kayla R. Whittington

Honors Theses

Photodynamic therapy (PDT) is a treatment modality for various illnesses, including some types of cancer. Lung cancer is the leading cause of cancer death in the United States. The prevalence of lung cancer in certain gender, racial, ethnic, and socioeconomic groups add to existing health disparities in the United States. For this reason, it is necessary to address the social determinants underlying lung cancer disparities, as well as improve treatment options. These treatment options should be cost effective, convenient, and increase survival rates. This research focused on synthesizing novel water-soluble porphyrin compounds for use as photosensitive agents in PDT for …


Honokoil Treatment On Glioblastoma Cells, Julianne Weaver Apr 2021

Honokoil Treatment On Glioblastoma Cells, Julianne Weaver

Honors Theses

Glioblastoma is a malignant brain tumor without effective treatment options available because of its resistance to chemotherapy and radiation. This specific type of cancer is difficult to treat because the cancer stem cells that are not actively growing. These cells are dormant, which means they will not react to treatment because they are not dividing, and it is these cells that result in the high prevalence of relapse. Honokiol is a Chinese magnolia species that is known for its anti-inflammatory, anti-proliferative, and proapoptotic effects which make it an optimal candidate for glioma cell treatment. Honokiol was used in this experiment …


Effectiveness And Mechanism Of Action Of Modified Porphyrins For Photodynamic Therapy Of Triple Negative Breast Cancer Cells, Hannah Brandon Jan 2019

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 Breast Cancer One Porphyrin At A Time, Taylor C. Lymburner Jan 2019

Killing Breast Cancer One Porphyrin At A Time, Taylor C. Lymburner

Honors Theses

New treatments for cancer are continuously being developed and improved. One such treatment is Photodynamic Therapy, more commonly referred to as PDT. PDT is quickly becoming more popular due to its relative lack of side effects that are present in other treatments. In PDT, light-sensitive agents are required and are activated by light in the targeted cells. There are many types of PDT agents but the one focused on in this research is a four-pyrrole ring structure known as a porphyrin. The combination of H2 TPPC with 3- amino-oxetane-3-yl-methanol created the final product ofH2TPP-Oxo-MeOH. Once the porphyrin was formed, it …
