Cytotoxicity Of Platinum Anticancer Drugs In Mammalian Cell Lines Of Metastatic Cancer, Hosannah Evie
Cytotoxicity Of Platinum Anticancer Drugs In Mammalian Cell Lines Of Metastatic Cancer, Hosannah Evie
Mahurin Honors College Capstone Experience/Thesis Projects
With the invention of advanced technology, focus has been put on understanding and looking for potential cures for many diseases, one of which is cancer. The difference in the leaving and non-leaving ligands of the FDA approved cancer drugs contributes to the differential cell specific cytotoxic effects. These drugs such as oxaliplatin approved for colorectal cancer, cisplatin approved for testicular cancer, and their analogs were used to treat different cancer cell lines in an MTT assay. This project aims to determine how changing the molecular shape of these compounds affects their uptake and toxicity into different cell lines. The assay …
Binding Of Oxaliplatin And Its Analogs With Dna Nucleotides At Variable Ph And Concentration Levels, Rippa Sehgal
Binding Of Oxaliplatin And Its Analogs With Dna Nucleotides At Variable Ph And Concentration Levels, Rippa Sehgal
Masters Theses & Specialist Projects
Oxaliplatin is one of the three FDA-approved platinum anticancer drugs and considered a third generation drug, discovered after the first generation drug cisplatin and second generation drug carboplatin. It is known to react with proteins and DNA nucleotides in the body. Reaction with DNA occurs primarily at guanosine residues and secondarily at adenine residues for oxaliplatin and other platinum drugs. We have previously studied oxaliplatin and an analog with additional steric hindrance in the amine ligand and found that the analog had different reactivity with methionine. Now, we have prepared oxaliplatin and its three analogs Pt(Me2dach)(ox), Pt(en)(ox) and Pt(Me4en)(ox) and …
Functionalization And Modification Of Naphthaquinone Analogs As Her2 Kinase Inhibitors, Divya Jyothi Lella
Functionalization And Modification Of Naphthaquinone Analogs As Her2 Kinase Inhibitors, Divya Jyothi Lella

HER2 overexpression in breast cancer tumors predicts lower overall survival. Because of the aggressive nature of HER2 tumors and the association with metastatic disease, the HER2 receptor holds great promise as a therapeutic target in metastatic breast cancer. We are developing small molecule inhibitors that bind to the ATP binding site of the tyrosine kinase domain in order to inhibit tyrosine auto-phosphorylation. This process controls biological pathways that mediate the cell growth. In normal cells this process is highly controlled. We are targeting the modification of the side chain of the hydroxy methyl group of 2-Hydroxy methyl-5,8-dimethoxy-1,4-naphthaquinone. These compounds should …
Characterization And Reaction Of An Analog Of The Anticancer Drug Oxaliplatin, Jonathan D. Hendrie
Characterization And Reaction Of An Analog Of The Anticancer Drug Oxaliplatin, Jonathan D. Hendrie
Mahurin Honors College Capstone Experience/Thesis Projects
Oxaliplatin is an anticancer drug that reacts with DNA, RNA, and proteins both in vitro and in vivo. Our research focuses on synthesizing analogs of oxaliplatin and understanding how bulky ligand groups affect reaction with amino acids. (R,R)-N,N’-dimethyl-1,2-diaminocyclohexane platinum(II) oxalate or Pt(Me2dach)(ox) varies from oxaliplatin or Pt(dach)(ox) in that it has one methyl group attached to each platinum coordinated nitrogen. Nuclear Magnetic Resonance (NMR) spectroscopy has shown that the reactions of N-Acetylmethionine (N-AcMet) with Pt(Me2dach)(ox) and Pt(dach)(ox) proceed at similar rates suggesting that the methyl groups of Pt(Me2dach)(ox) have little effect on the initial reaction. Whereas the reaction of Pt(dach)(ox) …
Reactions Of Platinum(Ii) Compounds With Selenium Containing Amino Acids, Stephanie Robey
Reactions Of Platinum(Ii) Compounds With Selenium Containing Amino Acids, Stephanie Robey
Masters Theses & Specialist Projects
Platinum(II) anticancer medications essentially react with DNA forming kinks in
the double helix of DNA and causing apoptosis. It has also been noted that these
anticancer medications react with methionine and cysteine in the body. With the new discoveries of selenium containing amino acids including selenomethionine and selenocysteine, new research is ongoing to see what types of products can be formed from these amino acids. Our research reacts [Pt(Met-S,N)Cl2] 2+ with selenomethionine to determine what types of products are produced. Monochelates including [Pt(SeMet-Se,N)Cl2] 2+ have formed two isomers, …
