Determination Of Anxiolytic And Antidepressant Medicines In New York City Wastewater Samples, Jasmine J. Gayle May 2019

Determination Of Anxiolytic And Antidepressant Medicines In New York City Wastewater Samples, Jasmine J. Gayle

Student Theses

Wastewater-based epidemiology (WBE) provides information about a population’s exposure to certain chemical agents, such as drugs of abuse and medicines, by the analysis of human biomarkers, also known as excretion products, in wastewater samples. Although this is a growing field worldwide, mainly in Europe, Oceania, and Asia, limited data from the US are currently available. We developed and validated an analytical method to quantitatively and qualitatively determine the presence of commonly prescribed drugs to treat anxiety (alprazolam, buspirone, clonazepam, lorazepam, and propranolol) and depression (bupropion, citalopram, clomipramine, duloxetine, fluoxetine, imipramine, paroxetine, sertraline, and venlafaxine) in wastewater using liquid chromatography ...


Preparation Of Enantioenriched Alkyltin Species And Their Application In Stereospecific Transformations, Glenn O. Ralph May 2019

Organometallic reagents containing the tin-carbon bond are used extensively in modern synthetic chemistry for the formation of new bonds to carbon. Over recent decades, transition metal catalyzed cross coupling reactions between two C(sp2) centers have been widely developed. However, the introduction of a C(sp3) center complicates the catalytic cycle, and opens unproductive chemical pathways which lead to isomerization, elimination, and racemization. Our lab has developed a modified-Stille reaction to combat the deleterious effects of β-hydride elimination. Our protocol enables unactivated 2° alkyl organotin nucleophiles to undergo efficient cross coupling reactions with C(sp2) electrophiles, avoiding ...


Ligand-Protein Binding Of Cantharidin And Norcantharidin On Hsf1: A Docking Study, Daniel Coyle Apr 2019

Ligand-Protein Binding Of Cantharidin And Norcantharidin On Hsf1: A Docking Study, Daniel Coyle

HON499 projects

Previous research provides experimental evidence that cantharidin acts as an inhibitor of HSF1 in cancer cells whereas the similar norcantharidin exhibits no inhibitory activity on HSF1. This computational study utilized Autodock to suggest both binding site(s) and binding energies of cantharidin and norcantharidin on HSF1. This study found cantharidin to consistently bind stronger than norcantharidin in the same area on HSF1 when assuming a rigid protein structure.


Bisthioether Stapled Peptides Targeting Polycomb Repressive Complex 2 Gene Repression, Gan Zhang Feb 2019

Interactions between proteins play a key role in nearly all cellular process, and therefore, disruption of such interactions may lead to many different types of cellular dysfunctions. Hence, pathologic protein-protein interactions (PPIs) constitute highly attractive drug targets and hold great potential for developing novel therapeutic agents for the treatment of incurable human diseases. Unfortunately, the identification of PPI inhibitors is an extremely challenging task, since traditionally used small molecule ligands are mostly unable to cover and anchor on the extensive flat surfaces that define those binary protein complexes. In contrast, large biomolecules such as proteins or peptides are ideal fits ...


Antitumor Properties Of Imidazolium Salts, Jenna Frantz Jan 2019

Antitumor Properties Of Imidazolium Salts, Jenna Frantz

Williams Honors College, Honors Research Projects

This is the final write-up for an honors research project for the University of Akron Williams Honors College. Synthesis of novel imidazolium salts was conducted. Following synthesis of imidazolium salts, the stability of the compound was tested at 37°C over a 72-hour period to give preliminary information about drug stability in vivo. 2D NMR was also conducted to confirm the structure of TPP-1. The student wrote an experimental protocol for the use of C57BL/6 mice and performed the online CITI training by the IRB to prepare to work with animals in a study of the antitumor properties of ...
