Use Of Beta-Antagonists Or Hmg-Coa Reductase Inhibitors For Cardioprotection During Chemotherapy In Oncology Patients, Nicole Streich

Physician Assistant Scholarly Project Posters

Over the years, oncologists are better able to fight cancer and have increased cancer survival, but we are also finding that these lifesaving therapies can affect the heart and other parts of the body in a negative way. Chemotherapy is excellent at destroying cancer cells, but it also causes collateral damage to other healthy cells. There are certain chemotherapeutic agents that are known to cause cardiotoxicity. Currently we are monitoring the heart function of the patients who are receiving these cardiotoxic drugs prior to starting the chemotherapy as well as during and after treatment. However, there are currently no recommendations …

Can Nanotechnology Be The Leading Method In Detecting And Treating Cerebral Tumors?, Daniel D. Singh, Zuri Jules-Culver

OUR Journal: ODU Undergraduate Research Journal

Nanotechnology refers to the manipulation or design of materials and structures with desired features in the 1nm–1000 nm size range. The blood brain barrier (BBB) is a major obstacle that drugs must overcome in order to reach tumor cells. The role of this barrier is to transport essential nutrients while protecting and regulating the internal environment. Nanoparticles have been shown to transport drugs through this barrier and accumulate in tumor cells. This is significant since nanoparticles are drug carriers allowing chemotherapeutic drugs to accumulate in target areas (Sun et al., 2017). This is possible because they are able to be …

Improving Dopamine Monitoring With Ncam And The Effects Of Intranasal Oxytocin On Dopamine Signaling In The Rat Brain, Darren Earl Ginder

EWU Masters Thesis Collection

Dopamine (DA) is a neurohormone highly involved in learning and memory. Oxytocin (OXT), another neurohormone, has also been implicated in learning and memory. Fast-scan cyclic voltammetry (FSCV) is a method used for the real-time examination of DA neurotransmission in the brain. Implanting FSCV electrodes is an invasive technique that likely results in an inflammatory response (i.e. gliosis) that can restrict FSCV recording of DA signals. Neural cell adhesion molecule (NCAM) may reduce gliosis and potentially improve the ability of FSCV electrodes to monitor DA signaling. Chapter 1 Methods: FSCV electrodes were coated with NCAM and implanted in the rat brain. …

Development Of A Chemical Genetic Screen To Identify Compounds That Enhance Laromustine Cytotoxicity, Xiaoou Wang

Honors Theses

Laromustine is a chemotherapeutic sulfonylhydrazine prodrug used in clinical trials against acute myeloid leukemia. Though laromustine showed some success in clinical trials, more experiments are needed to understand the hematological toxicity and the molecular mechanisms of patients’ resistance. This project aims to develop a strategy to identify compounds synergistic with laromustine in cultured leukemia cells from a library of 450 FDA-approved compounds through a forward chemical genetic screen. To optimize the screen, the cell seeding density, doubling time, and dose response curves were determined. The optimized concentration of HL60 cells in these experiments was determined to be between 25,000 and …

Understanding Structure-Activity Relationship Of Synthetic Cathinones (Bath Salts) Utilizing Methylphenidate, Barkha J. Yadav

Theses and Dissertations

Synthetic cathinones are stimulant drugs of abuse that act at monoamine transporters e.g. the dopamine transporter (DAT) as releasing agents or as reuptake inhibitors. More than >150 new synthetic cathinones have emerged on the clandestine market and have attracted considerable attention from the medical and law enforcement communities.

threo-Methylphenidate (tMP) is an FDA approved drug for the treatment of ADHD and narcolepsy, which also acts as a DAT reuptake inhibitor and is widely abused. tMP and synthetic cathinones share some structural similarities and extensive structure-activity relationship (SAR) studies on tMP have been conducted. However, much less is known about the …

Regorafenib Enhances Lethality Of Sildenafil And Curcumin In Colorectal Cancer Cells, Kervin Benjamin Owusu

Theses and Dissertations

In the United States, more than 130,000 people will be diagnosed with colorectal cancer (CRC) each year and an estimated 50,000 people will die from the disease. Standard of care (SOC) therapies for CRC combine multiple cytotoxic chemotherapeutic drugs. These combinations have varying degrees of effectiveness and can often result in significant patient morbidity. For second recurrence patients, the multi-kinase inhibitor, regorafenib, is an approved agent, but is often poorly tolerated at current doses. In the current study, we propose to develop therapeutic regime of combining agents with modest toxicity profiles: curcumin and sildenafil with regorafenib. Using clinically achievable enterohepatic …

Pharmacologic Profiling Of Novel Compounds Via Fluorometric Analyses Of Monoamine Transporter Responses, Ashkhan Hojati

Theses and Dissertations

In humans and other organisms, monoaminergic systems are crucial in neuronal function and behavior. The monoamine transporters (MATs), which can be found on the presynaptic plasma membrane of neurons in the central nervous system (CNS), are crucial in the regulation of neurotransmitter concentration in the synaptic cleft. As the duration and concentration of neurotransmitters in the cleft affect further downstream signaling responses, these proteins are important targets for both understanding neuronal physiology and compounds of interest. Multiple theories exist proponing the contribution of MATs to a variety of mental and neurological disorders, including depression. This theory establishes that depression is …

A Complete Approach To Predict Biodistribution Of Nanomaterials Within Animal Species From In-Vitro Data, Edward Price

Electronic Theses and Dissertations

Smart drug-design for antibody and nanomaterial-based therapies allows for optimization of drug efficacy and more efficient early-stage pre-clinical trials. The ideal drug must display maximum efficacy at target tissue sites, but to track and predict distribution to these sites, one must have a mechanistic understanding of the kinetics involved with the individual cells of the tissue itself. This process can be tracked through biological simulations coupled with in-vitro approaches, which result in a rapid and efficient in-depth understanding of drug transport within tissue vasculature and cellular environment. As a result, it becomes possible to predict drug biodistribution within live animal …

Mechanisms And Thermodynamics Of The Influence Of Solution-State Interactions Between Hpmc And Surfactants On Mixed Adsorption Onto Model Nanoparticles, Salin Gupta Patel

Theses and Dissertations--Pharmacy

Nanoparticulate drug delivery systems (NDDS) such as nanocrystals, nanosuspensions, solid-lipid nanoparticles often formulated for the bioavailability enhancement of poorly soluble drug candidates are stabilized by a mixture of excipients including surfactants and polymers. Most literature studies have focused on the interaction of excipients with the NDDS surfaces while ignoring the interaction of excipients in solution and the extent to which the solution-state interactions influence the affinity and capacity of adsorption. Mechanisms by which excipients stabilize NDDS and how this information can be utilized by formulators a priori to make a rational selection of excipients is not known.

Toward An Enzyme-Coupled, Bioorthogonal Platform For Methyltransferases: Probing The Specificity Of Methionine Adenosyltransferases, Tyler D. Huber

Theses and Dissertations--Pharmacy

Methyl group transfer from S-adenosyl-l-methionine (AdoMet) to various substrates including DNA, proteins, and natural products (NPs), is accomplished by methyltransferases (MTs). Analogs of AdoMet, bearing an alternative S-alkyl group can be exploited, in the context of an array of wild-type MT-catalyzed reactions, to differentially alkylate DNA, proteins, and NPs. This technology provides a means to elucidate MT targets by the MT-mediated installation of chemoselective handles from AdoMet analogs to biologically relevant molecules and affords researchers a fresh route to diversify NP scaffolds by permitting the differential alkylation of chemical sites vulnerable to NP MTs that are unreactive to …

Hematologic Safety Of Chronic Brain-Penetrating Erythropoietin Dosing In App/Ps1 Mice, Jiahong Sun, Joshua Yang, Kathrine Whitman, Charlene Zhu, David H. Cribbs, Ruben J. Boado, William M. Pardridge, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Introduction: Low blood-brain barrier (BBB) penetration and hematopoietic side effects limit the therapeutic development of erythropoietin (EPO) for Alzheimer's disease (AD). A fusion protein of EPO and a chimeric monoclonal antibody targeting the mouse transferrin receptor (cTfRMAb) has been engineered. The latter drives EPO into the brain via receptor-mediated transcytosis across the BBB and increases its peripheral clearance to reduce hematopoietic side effects of EPO. Our previous work shows the protective effects of this BBB-penetrating EPO in AD mice but hematologic effects have not been studied. Herein, we investigate the hematologic safety and therapeutic effects of chronic cTfRMAb-EPO dosing, …

Targeting Lipoprotein Biogenesis: Considerations Towards Antimicrobials, Toufic El Arnaout, Tewfic Soulimane

Articles

Decades have passed without approval of a new antibiotic class. Several companies have recently halted related discovery efforts because of multiple obstacles. One promising route under research is to target the lipoprotein maturation pathway in light of major recent findings and the virulence roles of lipoproteins. To support the future design of selective drugs, considerations and priority-setting are established for the main lipoprotein processing enzymes (Lgt, LspA, and Lnt) based on microbiology, biochemistry, structural biology, chemical design, and pharmacology. Although not all bacterial species will be similarly impacted by drug candidates, several advantages make LspA a top target to pursue …
