Synthesis Of Novel Long Chain Unsaturated Fatty Acid Analogs Of Capsaicin, Eli Bettiga

Honors Theses

A number of key studies have shown that the natural product capsaicin displays in vitro and in vivo antitumor effects against a variety of cancers, however, both the analgesic and cancer-related therapeutic potential of capsaicin have been limited by its unpleasant pungent side effects and modest potency. N-acyl vanillylamides (N-AVAMs) are a unique class of compounds that are simple side chain modified capsaicin derivatives. Limited structure-activity relationship (SAR) studies of N-AVAMs demonstrated that substitution of the capsaicin side-chain with longer unsaturated fatty acid groups results in non-pungent analogs with improved anti-invasive activity relative to capsaicin. In an effort to ultimately …

Pharmaceutical Sciences and Research

The COVID-19 pandemic has been occurring approximately for more than 1 year. This pandemic has been a health issue that hits all countries in the world caused by the transmission of SARS-CoV-2 virus from one individual to another. The symptoms showed from the infected are fever, shortness of breath, dry cough, headache, and sore throat, among others. The SARS-CoV-2 virus is transmitted through sneezing, coughing, talking, and touching infected objects. Along with this transmission, the SARS-CoV-2 virus will continue to mutate. This mutation becomes an obstacle as well as a challenge to find drugs that can overcome the SARS-CoV-2 virus …

Ciliary Extracellular Vesicles Are Distinct From The Cytosolic Extracellular Vesicles, Ashraf M. Mohieldin, Rajasekharreddy Pala, Richard Beuttler, James J. Moresco, John R. Yates Iii, Surya M. Nauli

Pharmacy Faculty Articles and Research

Extracellular vesicles (EVs) are cell‐derived membrane vesicles that are released into the extracellular space. EVs encapsulate key proteins and mediate intercellular signalling pathways. Recently, primary cilia have been shown to release EVs under fluid‐shear flow, but many proteins encapsulated in these vesicles have never been identified. Primary cilia are ubiquitous mechanosensory organelles that protrude from the apical surface of almost all human cells. Primary cilia also serve as compartments for signalling pathways, and their defects have been associated with a wide range of human genetic diseases called ciliopathies. To better understand the mechanism of ciliopathies, it is imperative to know …

Pharmacy Faculty Articles and Research

Despite extensive efforts to repurpose approved drugs, discover new small molecules, and develop vaccines, COVID-19 pandemic is still claiming victims around the world. The current arsenal of antiviral compounds did not perform well in the past viral infections (e.g., SARS), which casts a shadow of doubt for use against the new SARS-CoV-2. Vaccines should offer the ultimate protection; however, there is limited information about the longevity of the generated immunity and the protection against possible mutations. This study uses Human Coronavirus 229E as a model coronavirus to test the hypothesis that effective delivery of virus-specific siRNAs to infected cells will …

Save The Rich, Connor Harris

English Department: Research for Change - Wicked Problems in Our World

The problem of medication pricing and lobbying in the healthcare industry has caused millions of people within the United States to not be able to afford medications essential to their lives. Pharmaceutical companies are taking advantage of the need people have for certain drugs by setting the sale price far higher than it costs to produce. My suggested solution is to make lobbying illegal in the United States so that pharmaceutical companies would not have control over government officials who pass laws to help or hurt the issue of medication pricing. Illegalizing government lobbying will take away the incentive politicians …

Makara Journal of Science

This study describes the development of N-benzyl-1,10-phenantrolinium salt as an antiplasmodium agent. The salt, that is, 1-(4-ethoxy-3-methoxybenzyl)-1,10-phenanthrolin-1-ium bromide, was prepared using vanillin as the starting material in four simple synthetic steps. First, the alkylation of vanillin using diethyl sulfate produced 4-ethoxy-3-methoxybenzaldehyde in 79% yield. Second, the reduction of the protected vanillin by NaBH₄ through the grinding method allowed us to obtain 4-ethoxy-3-methoxybenzyl alcohol in 96% yield. Next, the bromination of the benzyl alcohol under solvent-free condition led to the formation of the corresponding benzyl bromide, which in turn underwent bimolecular nucleophilic substitution with 1,10-phenanthroline to produce the desired …

McKelvey School of Engineering Graduate Student Theses & Dissertations

Liposomal delivery of Remdesivir for localized and targeted treatment of COVID-19

COVID-19 is a serious, and in many cases lethal, disease that is caused by infection of the upper respiratory tract by the novel betacoronavirus, SARS-Cov-2 virus. This disease has a very high mortality rate and has affected the world in a global pandemic. SARS-Cov-2 binds to the ACE2 receptor via the receptor-binding domain (RBD) in the S protein. After this, the virus fuses with the cell membrane by the formation of a six-helix bundle. Thus, the S protein plays a major role in ensuring that the virus attaches to …

Association Of Electronic Prescription In Controlled Substances Used, Archana Suwal, Jemima Akinyi Okonjo

Theses, Dissertations and Capstones

Introduction: Controlled substances have been described as pharmaceuticals or illegal medicines that act primarily on the central nervous system and could cause physical and mental dependence, eventually leading to addiction. Prescription opioids were a significant contributor to the opioid epidemic, accounting for more than 70,000 opioid-related overdose deaths, including illicit and prescription opioids, between 2018 and 2019. The Electronic Prescriptions for Controlled Substances (EPCS) initiative recently aimed to reduce rates of prescription opioid addiction, abuse, diversion, and death. The system for controlled substances had become more widely used as providers and governments trying to combat the opioid problem. Because …

Investing Into Domestic Manufacturing Of Critical Medication And Vaccines For The Federal Government, Sharon Low

All Reports

While the federal government has made numerous public announcements regarding their stimulus plan and promises to increase the domestic capacity to produce personal protective equipment, vaccines, and medical equipment, a critical aspect that has been neglected is the serious and ongoing shortages of critical medication. The government has promised to provide 4.28 billion to expand testing and contact tracing capacities, 7.5 billion towards PPE, and 500 million to the provinces and territories for “critical health care system needs and support for mitigation effects.” While these efforts as part of Trudeau’s Safe Restart Agreement are a good place to begin reducing …

The developed Low-Volume Mixer-Heater (LVMH) …

Understanding The Impact Of Solvents In Oral Solid Dosage Formulation And Process Development, Matthew Kyle Defrese

Theses and Dissertations--Pharmacy

The successful delivery of chemical compounds for the purpose of therapeutic treatments and prophylactics is a substantial undertaking in modern drug development. Notably, the adoption of high throughput screening techniques has led to the proliferation of poorly water soluble and/or highly potent molecules which further complicate development activities. Spray dried amorphous solid dispersions are an increasingly important formulation strategy to overcome solubility issues while wet granulation approaches are the method of choice for the preparation of highly potent APIs in oral solid dosage forms.

A common connection between these critical techniques is their reliance on solvent-based processing that can often …

Introduction: Intractable epilepsy in children can significantly impair quality of life and anti-epileptic drugs (AEDs) do not adequately reduce seizures for all pediatric patients. Recently, cannabidiol (CBD), one of the main compounds of marijuana, has shown promise as a potential treatment for uncontrolled seizure activity. This paper poses the following question: In pediatric patients with drug-resistant epilepsy, is cannabidiol (CBD) more effective in reducing seizure activity than traditional anti-epileptic drugs …

Opioid Use Disorder: The Timeline For Medication Assisted Therapy, Alexander Cristofori

Capstone Showcase

Opioid Use Disorder is patterns of opioid use leading to withdrawal, giving up important life events in order to use opioids, and excessive time spent using opioids, to name a few diagnostic criteria. The clinical progression of the disorder involves periods of acute exacerbation and remission that are cyclic in nature. Treatment is most effective when it includes both pharmacological and psychosocial modalities, referred to as medication assisted therapy (MAT). Three drugs used commonly in MAT-based treatment for OUD from oldest to newest include Methadone, Buprenorphine-naloxone, and Naltrexone. Treatment program models that prioritize total abstinence from the addictive substance attached …

Naloxone/Buprenorphine, Methadone, Naltrexone And Their Role In Medication Assisted Treatment, Robert Barrett

Capstone Showcase

Abstract

Opioid use disorder (OUD) is an increasingly common diagnosis that has drastically increased in the last 5 years. Though multiple treatment modalities exist for treating OUD (naltrexone, buprenorphine, methadone), few studies have compared treatment outcomes in adults on long term therapy. This is an important topic to understand as providers as we will undoubtedly come into contact with patients either actively abusing opioid antagonists or in recovery from opioid abuse. Since the introduction of Oxycontin and subsequent over prescription of opioid analgesics, opioid overdoses have increased by over twelve-fold. Once providers began to realize a widespread pattern of abuse, …

Vaccine Clinical Trials And Data Infrastructure, Ana Santos Rutschman

All Faculty Scholarship

We find ourselves at a momentous turn in the history of vaccines. The COVID-19 pandemic triggered a quasi-global vaccine race that not only compressed vaccine research and development (R&D) timelines, but also paved the way for the administration of a new type of vaccine technology – mRNA vaccines, which work in substantially different ways from the vaccines in use before the pandemic.

While the process of bringing emerging COVID-19 vaccines to market has taken place in an unusually short timeframe, it was largely predicated on the same scientific and regulatory processes that govern the development, approval and deployment of new …

A Semiparametric Modeling Approach For Analyzing Clinical Biomarkers Restricted To Limits Of Detection, Sandipan Dutta, Susan Halabi

Mathematics & Statistics Faculty Publications

Before biomarkers can be used in clinical trials or patients' management, the laboratory assays that measure their levels have to go through development and analytical validation. One of the most critical performance metrics for validation of any assay is related to the minimum amount of values that can be detected and any value below this limit is referred to as below the limit of detection (LOD). Most of the existing approaches that model such biomarkers, restricted by LOD, are parametric in nature. These parametric models, however, heavily depend on the distributional assumptions, and can result in loss of precision under …
