A Mini Review : Clinically Significant Potential Drug-Drug Interactions In Covid-19 And Comorbid Therapy, Ana Khusnul Faizah, Nani Wijayanti Dyah Nurrahman, Oki Nugraha Putra

Pharmaceutical Sciences and Research

Coronavirus disease 2019 (COVID-19) is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and can be aggravated by comorbid diseases. In administering COVID-19 therapy, we need to consider potential drug-drug interactions (pDDIs) with comorbid drugs. Most patients with comorbid diseases get polypharmacy, therefore the risk of pDDIs increases. Potential drug-drug interactions can cause unwanted effects such as toxicity to death. There is no on-label therapy for COVID-19 but FDA has Emergency Use Authorization (EUA) for hydroxychloroquine, chloroquine, azithromycin, remdesivir, ritonavir, and lopinavir. Some COVID-19 treatment potential drug-drug interactions have a level of severity C and D, so …

Hybrid Cyclic/Linear Peptides In A Multi-Component Lipid Structure As A Sirna Delivery System, Abdulaziz Alasmari

Pharmaceutical Sciences (MS) Theses

Delivering siRNA is challenging due to many obstacles, such as extremely short in vivo half-life, rapid elimination via glomerular filtration, and inability to cross cell membranes due to the hydrophilic and negatively-charged nature. Thus, a delivery system is needed to deliver the siRNA into the cells by crossing the negatively-charged phospholipid cell membrane. The goal of this project was to design hybrid cyclic-linear peptides as siRNA delivery system. We designed and synthesized hybrid cyclic-linear peptides [R5K]W5, [R6K]W6, and [R5K]W7 containing positively-charged arginine residues attached to hydrophobic tryptophan chains for more efficient interaction with siRNA and to improve siRNA internalization into …

Commentary: Phytocannabinoids As Therapeutic Agents To Combat Chronic Gingival Disease., Nick Narek Ohanian

Pacific Journal of Health

The therapeutic potential of cannabis has been harnessed for thousands of years yet the United States Food and Drug Administration (FDA) has still not approved cannabis as a safe or effective drug. The FDA has, however, approved the manufacturing of pharmaceutical drugs, which contain a “synthetic version of a substance that is present in the marijuana” and other compounds that mimic its action. A search of the US National Library of Medicine and National Institute of Health for keywords “CBD” and “Periodontitis” together yields only 2 publications. Although the current State and Federal regulations on the use of cannabis for …

Ocular, Neural, And Cellular Biodistribution Of Multifunctional Antioxidants, Damian Daszynski

Theses & Dissertations

Aging is a complex biological process which stems from a growing imbalance between the regenerative capacity of an organism and endogenous as well as exogenous damaging factors. This imbalance leads to the slow deterioration of individual cells, organs, and eventually the entire organism. The free radical theory of aging combines the evolutionary and mechanistic aspects of aging, postulating that the innate process is caused by deleterious, irreversible, and inevitable changes in biological systems caused by oxidative damage that accumulates over the lifespan. Evidence of this phenomenon is supported by the pathogenesis of age-related diseases, such as age-related macular degeneration and …

Fluorometric Characterization Of A Methylene Blue Derivative Sensitive To Reactive Oxygen Species (Ros), Matthew Weeks

Honors Theses

Methylene blue (MB) has many uses within both microbiology and pharmacology. MB can treat disorders such as methemoglobinemia, malaria, Alzheimer’s disease, and certain forms of cancer. MB is also useful for molecular imaging due to its off-on fluorescent capabilities. MB derivatives with a urea bond at the 10-N position have been cleavable by triggers such as light. However, I was interested in sensitivity to reactive oxygen species (ROS). In this study, I wanted to determine if the MB derivative MB-EA exhibited sensitivity to ROS. MB-EA was exposed to varying concentrations of hydrogen peroxide and MB release was measured. I concluded …

Development Of Fluorescent Hyaluronic Acid Nanoparticles For Intraoperative Tumor Detection, Nicholas E. Wojtynek

Theses & Dissertations

Surgical resection remains to be the primary treatment for the majority of solid tumors, including breast cancer. The complete removal of the primary tumor, local metastases, and metastatic lymph nodes dramatically improve a patient’s treatment outcome and prognosis. Nevertheless, surgeons are limited to tactile and visual cues in distinguishing malignant and healthy tissue. This can result in a positive surgical margin (PSM), which occurs when tumor goes undetected and is left behind in the surgical cavity. PSMs decreases a patient’s prognosis and necessitate additional treatment in the form of surgery, radiation, and chemotherapy. An emerging imaging modality, known as fluorescence-guided …

Pilot Study Exploring The Effect Of Targeted Cox-2 Inhibition In Macrophages Responding To Neuronal Injury; Promoting Enhanced Axonal Regeneration, Alyssa Brauckmann

Electronic Theses and Dissertations

Celecoxib nanoemulsion (CXB-NE) has been developed as a macrophage targeted analgesics by Dr. Janjic and her team at Duquesne University, (Janjic et al, 2018; Liu et al, 2020; Saleem et al, 2019b; Vasudeva et al, 2014). The CXB-NE nanoemulsion carrying a Nonsteroidal Anti-inflammatory (NSAID) inhibitor of COX-2 activity result in a reduction in PGE2 expression in macrophages. Using CXB-NE in rats that have peripheral nerve injury constricting the sciatic nerve relieves hypersensitivity, a pain-like behavior. The treatment also decreases inflammation associated with this chronic constriction injury (Janjic et al, 2018; Saleem et al, 2019b; Stevens et al, 2019). In this …

N1-(α,β-Alkene)-substituted phenylpyrazolopyrimidine derivatives with acetyl and functionalized phenyl groups at α- and β-positions, respectively, were synthesized by the reaction of 3-phenylpyrazolopyrimidine (PhPP) with bromoacetone, followed by a chalcone reaction with differently substituted aromatic aldehydes. The Src kinase enzyme assay revealed modest inhibitory activity (half maximal inhibitory concentration, IC₅₀ = 21.7–192.1 µM) by a number of PhPP derivatives. Antiproliferative activity of the compounds was evaluated on human leukemia (CCRF-CEM), human ovarian adenocarcinoma (SK-OV-3), breast carcinoma (MDA-MB-231), and colon adenocarcinoma (HT-29) cells in vitro. 4-Chlorophenyl carbo-enyl substituted 3-phenylpyrazolopyrimidine (10) inhibited the cell proliferation of HT-29 and SK-OV-3 by 90% …

The Effects Of An Adenosine A(2a) Agonist As An Adjunctive Treatment To Alleviate Sensorimotor Gating Deficits In A Rodent Model Of Schizophrenia, Hannah Rauhuff

Undergraduate Honors Theses

The adenosine system has become a promising target for the treatment of schizophrenia due to its unique relationship with dopamine D₂ receptors. Dopamine D₂ receptors display heightened sensitivity in schizophrenia, and inhibition of these receptors has been shown to alleviate some of the psychotic symptoms of the disorder. Inhibition of adenosine A(2A) receptors has been shown to decrease dopamine D₂ receptor sensitivity, making this receptor a potential target for treatment of the disorder. This effect occurs because adenosine A(2A) receptors form a mutually inhibitory heterodimeric complex with dopamine D₂ receptors. The present study looked at the …
