The Synthesis And Characterization Of Ionic Liquids Using Nitrogen-Based Cations For Transdermal Delivery, Jo Galloway
The Synthesis And Characterization Of Ionic Liquids Using Nitrogen-Based Cations For Transdermal Delivery, Jo Galloway
Honors Theses
The purpose of this research was to explore the synthesis mechanisms of water-soluble ionic liquids with nitrogen-containing cationic bases for future use in transdermal drug delivery and forensic science applications. Ionic liquids are salts with an organic cation and either an organic or inorganic anion. They have asymmetric structures, which means that the molecules don’t pack together as neatly as other salts do, therefore, they don’t crystallize as easily, and their melting points are lower. Ionic liquids have melting points below 100°C, and many are liquid at room temperature. Mechanistic studies reveal that the potency of ILs in enhancing transdermal …
Use Of Small Molecule Fanconi Anemia Pathway Inhibitors As Sensitizing Agents To Laromustine., Sam W. Marchant
Use Of Small Molecule Fanconi Anemia Pathway Inhibitors As Sensitizing Agents To Laromustine., Sam W. Marchant
Honors Theses
Laromustine is an experimental chemotherapeutic sulfonyl hydrazine prodrug shown in clinical trials to be effective against acute myeloid leukemia. The mechanism of action of laromustine involves interstrand crosslinking, via chloroethylation, and enzyme inhibition, caused by carbamoylation. The work described herein aims to investigate whether inhibition of the replication-dependent interstrand crosslink repair Fanconi Anemia pathway further sensitizes cells to laromustine. By measuring metabolic activity immediately after drug exposure, we find laromustine to be equally as cytotoxic towards Fanconi Anemia deficient and wild type cells. However, through clonogenic assays we show Fanconi Anemia mutations sensitize cells to laromustine’s anti-proliferative effect. Furthermore, we …
The Effects Of Omega-3 Fatty Acids On Intracellular Inositol Levels In Saccharomyces Cerevisiae, Jee Yeon (Joanne) Lee
The Effects Of Omega-3 Fatty Acids On Intracellular Inositol Levels In Saccharomyces Cerevisiae, Jee Yeon (Joanne) Lee
Honors Theses
Bipolar disorder is a severe and chronic debilitating mental disorder characterized by extreme mood swings between mania and depression. The current medications for bipolar disorder, lithium and valproate, have been associated with numerous negative side effects. Although the therapeutic mechanism by which lithium and valproate (VPA) exert their effect is unknown, a leading hypothesis implicates inositol depletion as a mechanism of action. On the other hand, omega-3-fatty acids have been shown to relieve symptoms of bipolar disorder. In this study, we compare the effects of VPA to the effects of decosahexaenoic acid (DHA) on Saccharomyces cerevisiae growth and intracellular inositol …
Effects Of Arginine On The Kinetics Of Bovine Insulin Aggregation Studied By Dynamic Light Scattering, Michael M. Varughese
Effects Of Arginine On The Kinetics Of Bovine Insulin Aggregation Studied By Dynamic Light Scattering, Michael M. Varughese
Honors Theses
In the fields of protein science and medicine, understanding the kinetics of protein aggregation are significant in the research and treatment of certain amyloid diseases such as Alzheimer’s. Previous studies have suggested that arginine can increase the solubility of certain proteins, suppress protein aggregation, and assist in the refolding of aggregated proteins; however, the molecular mechanisms by which arginine can influence protein aggregation are still unclear. Bovine insulin was employed as a model system for further understanding the effects of arginine on protein aggregation. Using Dynamic Light Scattering (DLS), we studied the concentration-dependent and temperature-dependent suppression of aggregation in insulin …
