Antiviral Effects Of Metalloshielding: Differential Antiviral Activity Of Polynuclear Platinum And Cobalt Compounds, Mary Zoepfl

Theses and Dissertations

The majority of antiviral drug development has focused on virus-specific discovery targeting discrete steps in the individual life cycles. Although great strides have been made for a number of clinically relevant diseases such as human immunodeficiency virus, influenza virus, and hepatitis B, broad spectrum antivirals do not exist. Broad spectrum antivirals would offer (1) treatment for viruses without specifically-targeted antivirals, (2) treatment for viruses which have developed resistance to their available treatments, and (3) a rapidly deployable treatment option in viral epidemics. Many viruses including human cytomegalovirus (HCMV), HIV, and SARS-CoV-2. rely on heparan sulfate (HS), a highly sulfated glycosaminoglycan …

The Therapeutic Potential Of Glycosaminoglycan Directed Metalloglycomics: Elucidating New Targets And Mechanisms For Polynuclear Platinum Complexes, James D. Hampton

Theses and Dissertations

Cancer remains a serious clinical problem and in order to continue to improve patient health outcomes, novel treatment strategies must continue to be developed. Platinum chemotherapies remain as one of the most widely successful classes of cancer therapeutic, with over 50% of cancer patients receiving a platinate at some point over the span of their treatment. However, intrinsic and extrinsic resistances limit their effectiveness, long term efficacy, and broad applicability to multiple cancer subtypes. Therefore, the development of new agents and strategies which can overcome these limitations are crucial for patient health. To this end a novel class of polynuclear …

Heparan Sulfate, A New Target For Platinum In Metastatic Tnbc, Samantha J. Katner

Abstract

Heparan Sulfate, A New Target for Platinum in Metastatic TNBC

Author: Samantha J. Katner, Ph.D.

A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy

Virginia Commonwealth University, 2018

Advisor: Dr. Nicholas Farrell, Professor, Chemistry Department

Heparan sulfate proteoglycans (HSPGs), composed of the linear polysaccharide heparan sulfate (HS) conjugated to a protein core, are located on the cell surface and extracellular matrix. The HS chains display varying degrees of sulfation, which constitutes the molecular recognition motif for many HS-protein interactions. HSPGs, associated growth factors, and heparanase promote tumor progression by facilitating invasion, angiogenesis, …

Can A Metallated Cyclen Species Be Used To Prepare New Odorants?, Jalynn Taylor-Farmer

Undergraduate Research Posters

Scientists in the fragrance industry are constantly searching for new odors to create as well as new, more efficient processes to create them. Scientists mainly look for new ways to synthesize fragrances that will reduce the impact on the environment, produce them at lower costs, produce higher yields, and sometimes to produce a more potent odor [4]. In this research, we investigated the use of metallic macrocycles and/or metal-dioxygen chemistry to prepare new fragrances.

Cyclen (1,4,7,10-tetraazacyclododecane) has significant uses in many pharmaceutical and medicinal research developments such as advances in targeted cancer and Alzheimer’s agents. Macrocyclic amines like cyclen are …

Modified Seed Growth Of Iron Oxide Nanoparticles In Benzyl Alcohol: Magnetic Nanoparticles For Radio Frequency Hyperthermia Treatment Of Cancer, Stanley E. Gilliland Iii

Theses and Dissertations

Iron oxide nanoparticles have received sustained interest for biomedical applications as synthetic approaches are continually developed for precise control of nanoparticle properties. This thesis presents an investigation of parameters in the benzyl alcohol synthesis of iron oxide nanoparticles. A modified seed growth method was designed for obtaining optimal nanoparticle properties for magnetic fluid hyperthermia. With a one or two addition process, iron oxide nanoparticles were produced with crystallite sizes ranging from 5-20 nm using only benzyl alcohol and iron precursor. The effects of reaction environment, temperature, concentration, and modified seed growth parameters were investigated to obtain precise control over properties …
