Electronic Theses and Dissertations
Alzheimer's disease (AD) is one of the most dreaded forms of progressive neurodegenerative diseases. The two main hallmarks of AD are the formation of amyloid senile plaques and neurofibrillary tangles. Cyclin dependent kinase 5 (CDK5) is a proline directed serine/threonine kinase, which expressed primarily in the central nervous system. In the biochemical process the CDK5-natural activator, p35 is cleaved by calpain to a shorter protein p25, which in turn hyperphosphorylates Tau, forms neurofibrillary tangles and causes AD. CDK5 deregulation is also indicated in other neurodegenerative diseases, such as Huntington's chorea, stroke, Parkinson's disease, amyotrophic lateral sclerosis, major depression and substance …

Electronic Theses and Dissertations
Aplysinopsins are tryptophan-derived natural products that have been isolated from a variety of marine organisms and have been shown to possess a range of biological activities. Initial synthesis of a library of 50 aplysinopsin analogs revealed that of the 12 serotonin receptor subtypes and 34 other CNS receptors, aplysinopsin analogs shoa high affinity for the 5-HT2B and 5-HT2C receptor subtypes, with selectivity for 5-HT2B over 5-HT2C. Bromination at C-4 and C-5 of the indole ring resulted in greater binding affinities, with Ki's as low as 35 nM. In addition, biological evaluation of the MAO-A and MAO-B inhibitory activities of these …

Community Pharmacists' Attitudes Toward An Expanded Class Of Nonprescription Drugs, Ruchitbhai Mukesh Shah
Electronic Theses and Dissertations
Objectives: there has been considerable discussion about creating a third class of drugs which would not require a prescription, but require a pharmacist's consultation upon purchase. Very recently the Food and Drug Administration (FDA) held a hearing which repositioned a third class as an expanded nonprescription drug class termed as the "new paradigm" using certain innovative technologies. The specific objectives of this study were to: 1) measure community pharmacists' attitudes toward an expanded nonprescription drug class under the FDA’s proposed "new paradigm"; 2) determine if attitudes of community pharmacists toward an expanded nonprescription drug class under the FDA’s proposed "new …
Structural Characterization And Bioactivity Of Cranberry Oligosaccharides, Kimberly M. Auker
Structural Characterization And Bioactivity Of Cranberry Oligosaccharides, Kimberly M. Auker
Electronic Theses and Dissertations
Complex carbohydrates from plant sources, such as the fruits of cranberry (Vaccinium macrocarpon Aiton), promote human health in a variety of ways. However, complete studies of carbohydrate function often hinge on a detailed understanding and thorough elucidation of the chemical structure. Several methods have been used in the structure elucidation of cranberry oligosaccharides, such as derivatization folloby analysis using gas chromatography-mass spectrometry (GC-MS). In this manner, the identity and quantity of glycosyl units within two cranberry oligosaccharides were investigated through hydrolysis of the oligomers and subsequent synthesis of trimethylsilyl and alditol acetate derivatives. Further analysis using partially methylated alditol acetate …

Scaffold Perception, Compharmacophore Model Development, And Quantitative Structure-Affinity Relationships Of Sigma Site Ligands, David Enos Watson
Electronic Theses and Dissertations
Sigma receptors are endogenous proteins with potential utility in treating psychological disorders, ischemia, the psychological and convulsive effects of drugs of abuse, and as an imaging agent for cancerous tissues, among others. Drug design efforts targeting these receptors have been hindered by a lack of structural information of the receptors themselves. Traditional ligand-based approaches have succeeded in generating many compounds with high affinity, and quite a few with selectivity for σ-1 receptors. There are few selective ligands for use as pharmacological probes for the σ-2 receptor. Much effort has gone into exploring the structure activity relationships of ligands targeting these …
Synthesis Of A New Scytovirin Protein Derivative, Sd1-Sd2-Sd2, To Decrease Hiv-1 Binding Affinity, Alexandra M. Wood
Synthesis Of A New Scytovirin Protein Derivative, Sd1-Sd2-Sd2, To Decrease Hiv-1 Binding Affinity, Alexandra M. Wood
Honors Theses
Scytovirin is a novel anti-viral protein isolated from the cyanobacterium Scytonema varium. This protein has produced great scientific interest for its anti-human immunodeficiency virus (HIV) activity. Scytovirin disrupts the mechanism of HV infection by binding to HIV-1 proteins glycoprotein 120, glycoprotein 160, and glycoprotein 41. It does not bind to the CD4 receptor on human immune cells. The wild-type protein consists of a single 95 amino acid chain. When folded, Scytovirin's amino acid sequence is arranged into two distinct domains, each with a high degree of sequence conservation. This implicates the importance of both domains in anti-HIV activity. Primers were …

Synthesis Of Natural Product-Based Sphingosine Derivatives, Zarana Daksh Chauhan
Electronic Theses and Dissertations
Marine sponges represent an excellent source of sphingolipids and their metabolites, especially sphingosine-1-phosphate (S1P). S1P plays an important role in cell differentiation, survival, proliferation and the immune response. The enzyme sphingosine kinase (SK) is critical for the phosphorylation of sphingosine to S1P and has been examined as a druggable target for the treatment of hyper-proliferative diseases, inflammation, cancer and other pathological conditions. Natural products that consist of an azetidine ring represents an interesting class of conformationally constrained scaffolds that may serve as effective lead compounds for SK inhibitor development. Hence, the goal of this thesis research was to synthesize natural-product …

Part A: Antimalarial Agents modified at the C-16 position of Artemisinin. Malaria is a widespread tropical and subtropical parasitic disease which is caused by malarial parasites and transmitted by the infected anopheles mosquitoe. The natural product artemisinin and its derivatives are currently considered the most effective drugs against drug resistant plasmodium falciparum. However, its undesired physicochemical proprieties have limited its usage. In order to improve its effectiveness, scientists around the world have developed novel methodology to synthesize artemisinin derivatives on different positions of the artemisinin skeleton. Previous work in our group has shown that many analogues modified at the C-16 …
