Toxicity Of Novel Platinum Compounds In Mammalian Cancer Cells, Vanesa Veletanlic Apr 2020

Toxicity Of Novel Platinum Compounds In Mammalian Cancer Cells, Vanesa Veletanlic

Masters Theses & Specialist Projects

There are currently three FDA platinum compounds approved for use as chemotherapeutics, where each drug has variable efficacies for different cancer types depending on cancer’s tissue of origin. The approved compounds are platinum(II) complexes with four coordination sites on the platinum atom allowing two types of ligands to attach: leaving ligands, which are removed from the platinum atom in solution, and non-leaving ligands, which remain complexed to the platinum. Carboplatin, the preferred compound used to treat ovarian and small-cell lung cancers, has a characteristic cyclobutanedicarboxylic acid leaving ligand and two ammonia non-leaving ligands. A novel compound, 1,1-cyclobutanedicarboxylato(ethylenediamine)platinum (II), or Pt(en)CBDCA, …


Ototoxicity Of Cisplatin, Pyriplatin, And Phenathriplatin In The Auditory Hybridoma Cell Line, Hei-Oc1, Alexandra Johnston Jan 2020

Ototoxicity Of Cisplatin, Pyriplatin, And Phenathriplatin In The Auditory Hybridoma Cell Line, Hei-Oc1, Alexandra Johnston

Mahurin Honors College Capstone Experience/Thesis Projects

Cisplatin is an anti-cancer drug which is effective against several cancers, but also causes harmful side-effects, including ototoxicity and hearing loss. While cisplatin is a bifunctional compound that forms coordinate covalent bonds with both strands of DNA, recently investigated monofunctional platinum(II) compounds bind to only one DNA strand, and may activate different cell-death mechanisms. As several monofunctional platinum(II) compounds have anti-cancer properties, but could target different cell-death pathways, they could potentially have different and reduced side-effects. In this study, the HEI-OC1 auditory hybridoma cell line was used to investigate the ototoxicity of cisplatin and two monofunctional platinum(II) compounds, phenanthriplatin and …
