Approaches Towards The Synthesis Of Ketamine Metabolites, Ann K. Patrick May 2020

Approaches Towards The Synthesis Of Ketamine Metabolites, Ann K. Patrick

Honors Theses

Major Depressive disorder (MDD) plagues society and stands at the forefront of research as MDD affects approximately 16% of the population. Pharmaceutical drugs, including the selective serotonin reuptake inhibitors (SSRIs), have been used for MDD treatment and remain a popular option today. However, current antidepressant treatments have proven to be ineffective in just less than half of the patients. Research continues with the goal to better understand the mechanisms of the pathology of depression and to search for other treatment options. For example, the stress-neurogenesis hypothesis investigates the role of stress and decreased neuroplasticity within MDD.

Supporting the stress-neurogenesis hypothesis, …


Silver-Catalyzed Synthesis Of Disubstituted Fluorinated Isoxazoles, Micah Stewart May 2020

Silver-Catalyzed Synthesis Of Disubstituted Fluorinated Isoxazoles, Micah Stewart

Honors Theses

The presence of fluorine can provide organic compounds with useful biological properties, such as increased metabolic stability and drug uptake. Because of these advantages, fluorinated compounds make up about 30% of the drug industry. However, fluorination of complex molecules is difficult due to fluorine’s high electronegativity.

Fluorinated isoxazoles are of particular interest in the pharmaceutical industry. Isoxazoles are five-membered heterocycles with oxygen and nitrogen in the 1, 2 positions that are able to engage in interactions unavailable to other ring structures, conferring advantageous biological properties upon compounds containing them. However, there are limited synthetic routes for fluorinated isoxazoles, and those …


Synthesis Of Aromatic Fluorinated Ketones For Evaluation At The Gaba Receptor, Madeline Griffin May 2020

Synthesis Of Aromatic Fluorinated Ketones For Evaluation At The Gaba Receptor, Madeline Griffin

Honors Theses

GABA is a neurotransmitter that inhibits the excitation of neurons. Targeting this specific receptor has the potential to inhibit the central nervous system and possibly treat addiction, anxiety, or mood disorders. Previous research has shown that fluorinated ketones can have valuable applications in the medicinal chemistry of addiction. Some fluorinated ketones have shown activity at the GABA receptor. The main goal of this project was to synthesize aromatic fluorinated ketones for biological evaluation at the GABAB receptor. Another goal was to compare both the monofluorinated and difluorinated analogues synthesized in order to quantify differences in activity from fluorination state. …


Design And Synthesis Of Novel Analogs As Potential Antitubercular Agents, Peggy Mccluggage May 2020

Design And Synthesis Of Novel Analogs As Potential Antitubercular Agents, Peggy Mccluggage

Honors Theses

Tuberculosis (TB) is an infectious, airborne disease which primarily infects the lungs. One-third of the world’s population is currently estimated to be infected with Mycobacterium tuberculosis (Mtb), the causative agent for TB [1]. Current treatment for this disease requires at least six months of taking multiple antibiotics with undesirable side effects [2]. Difficulty in complying to this regimen as well as the prevalence of HIV/AIDS has led to antimicrobial resistance seen in Mtb. In order to combat the Multi-Drug Resistant and Extensively-Drug Resistant strains of the disease-causing bacteria, preventative care and novel antibiotics are urgently needed [3]. The purpose for …


Gold Nanoparticles: Core Conversion Of Au144(Sch2ch2ph)60 To Au99(Sph-Ch3)42 Using Aromatic Thiolate Ligands And Crystallization Of Au99(Sph-Ch3)42, Elizabeth Turnage May 2020

Gold Nanoparticles: Core Conversion Of Au144(Sch2ch2ph)60 To Au99(Sph-Ch3)42 Using Aromatic Thiolate Ligands And Crystallization Of Au99(Sph-Ch3)42, Elizabeth Turnage

Honors Theses

The purpose of this thesis is to synthesize Au144(SCH2CH2Ph)60 using a two-step synthesis reaction, and then using this product to conduct a core conversion from Au144(SCH2CH2Ph)60 to Au99(SPh-CH3)42. The Au99(SPh-CH3)42 product will then be used to attempt to form crystals using five different crystal set-up methods. Au144(SCH2CH2Ph)60 is made with aliphatic thiolate ligands, and when it is placed in a mixture containing excess para-methyl benzenethiol, it undergoes a …
