Identification And Characterization Of Novel, Small Molecule Inhibitors Of Spermine Oxidase, Amelia Bryn Furbish
Identification And Characterization Of Novel, Small Molecule Inhibitors Of Spermine Oxidase, Amelia Bryn Furbish
MUSC Theses and Dissertations
The major intracellular polyamines spermine and spermidine are abundant endogenous compounds that are essential for cellular growth and development. Dysregulation of polyamine metabolism has been implicated as a key mechanism of injury across multiple forms of clinically challenging pathologies. Of the enzymes within the polyamine pathway, the catabolic enzyme spermine oxidase (SMOX) is of particular interest as it is subject to induction in response to infection, neuronal excitotoxicity, ischemia, and oxidative stress. In addition to the loss of radical scavenging capabilities associated with spermine depletion, catabolism of spermine by SMOX results in the production of toxic byproducts, including H2 …
Design And Synthesis Of Small Molecule Drugs For Cns Disorders, Kirsten T. Tolentino
Design And Synthesis Of Small Molecule Drugs For Cns Disorders, Kirsten T. Tolentino
Theses & Dissertations
Dopamine (DA) is an important neurotransmitter for the regulation and long-term function of the central nervous system (CNS). DA binds to Dopamine Receptors (DR) to stimulate or inhibit adenyl cyclase production to further elicit a pharmacological response. DRs were cloned, and it was determined that there are two families separated by their function and five total subtypes distinguished by their amino acid structure. The Dopamine 4 receptor (D4R) is the second least studied subtype but has high expression in the frontal cortex, amygdala, hippocampus, hypothalamus, globus pallidus, substantia nigra pars reticula, and thalamus. Dopamine signaling and transmission, especially in the …
Characterization Of Di-Aryl Urea Compounds Against Acute And Chronic Toxoplasma Gondii, Austin Sanford
Characterization Of Di-Aryl Urea Compounds Against Acute And Chronic Toxoplasma Gondii, Austin Sanford
Theses & Dissertations
Toxoplasma gondii is an obligate intracellular parasite that has infected nearly 60 million individuals in the United States alone. Acute infection causes ill effects to the fetus in utero when mothers are primarily infected, and to immunocompromised individuals. Chronic infection consists of quiescent tissue cysts located primarily in brain tissue and is capable of reverting back to the acute stage causing severe toxoplasma encephalitis in immunocompromised individuals. Current treatments for acute infection are lacking while there are no approved treatments for the clearance of chronic infection. The aim of this research was to evaluate a family of di-aryl urea compounds …
Validation And Application Of A Novel Target-Based Whole-Cell Screen To Identify Antifungal Compounds, Christian Alexander Dejarnette
Validation And Application Of A Novel Target-Based Whole-Cell Screen To Identify Antifungal Compounds, Christian Alexander Dejarnette
Theses and Dissertations (ETD)
Traditional approaches to drug discovery are inefficient and have several key limitations that constrain our capacity to rapidly identify and develop novel experimental therapeutics. To address this, we have devised a second-generation target-based whole-cell screening assay based on the principles of competitive fitness, which can rapidly identify target-specific and physiologically-active compounds. Briefly, strains expressing high, intermediate, and low levels of a preselected target protein were constructed, tagged with spectrally distinct fluorescent proteins (FPs), and mixed together. The pooled strains were then grown in the presence of various small molecules, and the relative growth of each strain within the mixed culture …
