Analyzing Functional Interactions Of Designed Peptides By Nmr Spectroscopy, Wonsuk Choi 2023 Chapman University

Analyzing Functional Interactions Of Designed Peptides By Nmr Spectroscopy, Wonsuk Choi

Pharmaceutical Sciences (MS) Theses

The development of small peptide-based therapeutics can be accelerated by the knowledge of relationships between the peptide structure and its functional interactions. Here, we report the analysis of two groups of synthetic peptides designed for two applications – broad bactericidal action and inhibition of protein-protein interactions in human cells. Novel amphiphilic peptides designed for antibacterial application incorporated arginine as cationic amino acids and non-natural amino acids that have aromatic side chains with similar hydrophobic properties as tryptophan. The interaction of lead cyclic peptides and their linear analogs with a phospholipid bilayer mimicking a bacterial membrane was studied using nuclear magnetic …

The field of Alzheimer’s disease (AD) has witnessed recent breakthroughs in the development of disease-modifying biologics and diagnostic markers. While immunotherapeutic interventions have provided much-awaited solutions, nucleic acid-based tools represent other avenues of intervention; however, these approaches are costly and invasive, and they have serious side effects. Previously, we have shown in AD animal models that tolfenamic acid (TA) can lower the expression of AD-related genes and their products and subsequently reduce pathological burden and improve cognition. Using TA as a scaffold and the zinc finger domain of SP1 as a pharmacophore, we developed safer and more potent brain-penetrating analogs …

Research Symposium

Background: Cancer is one of the most common destructive diseases and the second leading cause of death in humans. Among cancer, cervical cancer is the second most common malignancy among women globally. Thus, there is a continuous need to search for chemotherapeutic chemicals or naturally occurring drugs to resolve this global health problem. Piperine (1-piperoylpeperdine) is present in the fruits of black pepper (Piper nigrum Linn.) and long pepper (Piper longum Linn.). It possesses several pharmacological properties and in the present study we have evaluated its anti-cancer potential on human cervical adenocarcinoma (HeLa) cells.

Pharmaceutical Sciences and Research

Diabetic retinopathy is a complication of diabetes that is one of the top five causes of blindness in those over 50. The standard treatment is pan-retinal photocoagulation, which is effective but has established side effects. Anti-vascular endothelial growth factor (anti-VEGF) therapy becomes an alternative to avoid the side effects caused by laser therapy. This systematic review aims to know the effectiveness of anti-VEGF therapy compared to the pan-retinal photocoagulation laser therapy in patients with proliferative diabetic retinopathy. This review was carried out using a systematic review checklist on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). The articles reviewed …


Utilization Of Pvp-Pla Combination In Fabricating Theophylline-Loaded Filament For 3d Printing With Immediate Release Behavior, Arief Kurniawan, Silvia Surini 2023 Laboratory of Pharmaceutics and Pharmaceutical Technology, Faculty of Pharmacy, Universitas Indonesia, Depok, West Java, 16424, Indonesia

Utilization Of Pvp-Pla Combination In Fabricating Theophylline-Loaded Filament For 3d Printing With Immediate Release Behavior, Arief Kurniawan, Silvia Surini

Pharmaceutical Sciences and Research

Fused deposition modeling (FDM), known as a highly effective 3D printing technique, holds promise as an alternative approach to tablet manufacturing. While commonly employing thermoplastic polymers as starting materials, the integration of established pharmaceutical excipients remains unexplored. Polyvinyl pyrrolidone (PVP) is a frequently used excipient known for its potential to confer immediate-release properties to drugs. However, its suitability for extrusion is hindered by its thermal and melt-rheological properties. In contrast, polylactic acid (PLA), which has robust mechanical strength and thermal plasticity, was expected to overcome PVP’s limitations. This study aims to obtain drug-loaded filaments using the combination of PVP and …

Individual And Combined Effect Of Eudragit® Rs 100 And Eudragit® Rl 100 On Sustained Release Characteristics Of Ropinirole Hcl-Loaded Microparticles, Aamir Hayyat, Nabeel Siddique

Pharmaceutical Sciences and Research

Ropinirole HCl is a non-ergoline dopamine agonist which is recommended for the treatment of both Parkinson’s disease and Restless Legs Syndrome (RLS). Its half-life is about 6 hours and it is metabolized in the liver primarily by CYP1A2. Its metabolites are water-soluble and rapidly excreted from the body in urine. However, its oral bioavailability is low. Therefore, this current project aimed to produce and evaluate sustained release ropinirole microparticles coated with Eudragit® RS 100 and RL 100 by varying polymer types and concentrations. Ropinirole microparticles were prepared by oil in oil emulsion solvent evaporation technique. Emulsifier concentration was constantly …

Targeting Breast Cancer: The Familiar, The Emerging, And The Uncharted Territories, Hamidreza Montazeri Aliabadi, Arthur Manda, Riya Sidgal, Co Chung

Pharmacy Faculty Articles and Research

Breast cancer became the most diagnosed cancer in the world in 2020. Chemotherapy is still the leading clinical strategy in breast cancer treatment, followed by hormone therapy (mostly used in hormone receptor-positive types). However, with our ever-expanding knowledge of signaling pathways in cancer biology, new molecular targets are identified for potential novel molecularly targeted drugs in breast cancer treatment. While this has resulted in the approval of a few molecularly targeted drugs by the FDA (including drugs targeting immune checkpoints), a wide array of signaling pathways seem to be still underexplored. Also, while combinatorial treatments have become common practice in …

Design And Synthesis Of Small Molecule Drugs For Cns Disorders, Kirsten T. Tolentino 2023 University of Nebraska Medical Center

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 …

The Opioid Epidemic: How Genetics Play A Role In Addiction And Treatment, Kirsten Houston 2023 Murray State University

The Opioid Epidemic: How Genetics Play A Role In Addiction And Treatment, Kirsten Houston

Honors College Theses

The opioid epidemic is an issue within the pharmaceutical industry in the United States of America due to prescription and non-prescription substances being made available to the population. Opioids include chemical substances that affect the body and brain through opioid receptors, including the mu, kappa, and delta receptors. These substances are derived and synthesized from the poppy plant. Multiple causes have been linked to opioid abuse disorder, including but not limited to employment, income, housing, nutrition, mental health disorders, and genetics. By gathering information from previous literature, genetics may be the main cause of narcotic analgesic tolerance and abuse. Specific …


All Clear: A Workbook For Sexually Active Accutane Users Who Can Become Pregnant, Taylor Petersen 2023 Bowling Green State University

All Clear: A Workbook For Sexually Active Accutane Users Who Can Become Pregnant, Taylor Petersen

Honors Projects

Accutane is a pill-based derivative of Vitamin A used to treat cystic acne. The process to start and continue the medication each month is tedious and full of potential for error. This is especially true for female patients who are able to become pregnant as they have the additional step of monitoring and updating their birth control through an online portal. Patients are treated like numbers and there is little to no customization within Accutane treatment from patient to patient. To make this worse, reliable information about the drug is scarce and many turn to social media platforms or other …
