Nanoparticle Conjugated Photosensitizer For Targeted Photodynamic Inactivation Of Cancer Cells, Symone D. Crowder
Nanoparticle Conjugated Photosensitizer For Targeted Photodynamic Inactivation Of Cancer Cells, Symone D. Crowder
Honors College Theses
Photodynamic therapy (PDT) is considered to be a potential replacement for traditional methods of chemotherapy. It includes the administration of photosensitizing agents (PS), which generate reactive oxygen species (ROS) upon excitation at a specific wavelength. With new outlooks and techniques, cancer research is advancing each day. It has allowed the progress of several theranostic drug delivery systems (DDS) exploring the area of nanomedicine.2 In the present work, a Rhodamine derivative, Rhodamine 6G (R6G) was used as the PS. In general, rhodamine compounds undergo cytotoxic reactions on photoexcitation by electron transfer reactions with folic acid within cells, making them a favorable …

B7h6: A Cancer Biomarker For The Development Of Novel Immunotherapy Approaches, Mariana Phillips
Seton Hall University Dissertations and Theses (ETDs)
Cancer-based immunotherapy has led the evolution of biologics that can stimulate immune responses towards tumor eradication. The synthesis of small to intermediate size molecules with the targeting and effector functions of mAb may represent a novel class of immunotherapeutics that may overcome the limitations of their biological counterparts.Towards this objective, B7H6 has been identified as a protein ligand localized on the cell surface of transformed tumor cells. B7H6 binds specifically to the activating receptor NKp30, constitutively expressed on all resting and active NK cells. Upon ligand:receptor binding, B7H6 triggers NK cell activation and release of chemokines and pro-inflammatory cytokines such …
Design, Synthesis, And Anticancer Activity Of Ruthenium Complexes, Brock S. Howerton
Design, Synthesis, And Anticancer Activity Of Ruthenium Complexes, Brock S. Howerton
Theses and Dissertations--Chemistry
Ruthenium complexes show promise as light activated photodynamic therapy (PDT) prodrugs. Strained octahedral complexes were synthesized that produce a cytotoxic species upon light activation. pUC19 DNA damage in vitro experiments were carried out to determine the type of damage observed. In vivo cell experiments were carried out on the non-small lung cancer A549 cell line to determine the phototherapeutic window of the synthesized complexes. One mechanism of drug resistance via elevated levels of glutathione was addressed through in vitro binding studies carried out with UV-Vis spectroscopy and in vivo glutathione titrations in the A549 cell line. Several complexes were shown …
