Correlating The Physicochemical Properties Of Magnesium Stearate With Tablet Dissolution And Lubrication, Julie L. Calahan

Theses and Dissertations--Pharmacy

Magnesium stearate (MgSt) is the most commonly used pharmaceutical excipient and is present in over half the tablet formulations on the market. In spite of its popularity as an effective lubricant, it has been repeatedly recognized that there is significant variability between MgSt samples, which can cause inconsistent lubrication between batches of MgSt. The hypothesis of this research is that the batch-to-batch variability in tablet lubrication and dissolution observed in tablet formulations containing different MgSt samples can be correlated with differences in MgSt physicochemical properties (fatty acid salt composition, crystal hydrate form, particle size and surface area). Developing correlations between …

Novel Small Molecule Antifungals For Invasive Fungal Infections, Emily Dennis

Theses and Dissertations--Pharmacy

Human fungal pathogens cause a range of diseases from benign skin conditions (i.e., ringworm) to thrush, mucosal membrane infections, and life-threatening systemic infections including bloodstream infections (i.e., aspergillosis and candidiasis) and Cryptococcal meningitis. These systemic infections occur most often in immunocompromised individuals and have high mortality rates. Current antifungal agents used in the clinic belong to three main classes: the polyenes (e.g., amphotericin B (AmB)), the echinocandins (e.g., caspofungin (CFG)), and the azoles (e.g., fluconazole (FLC)). In addition, the antimetabolite pyrimidine analogue flucytosine is used in combination with AmB. The …

Development Of Dexamethsone Sodium Phosphate Loaded Nanoparticles For Treating Corneal Allograft Rejection, Vineet R. Kulkarni

Theses and Dissertations

Corneas are the most commonly transplanted tissue worldwide, with approximately 80,000 transplantations performed in the United States in 2018 alone. Corneal transplantation is used to restore the vision due to opaque corneas in various diseases such as fungal keratitis, keratoconus, Fuchs’s dystrophy, corneal ulceration, traumatic injury, abrasions or scarring, inflammation, and infection. Corneal transplant surgery could involve replacing the entire cornea (penetrating keratoplasty) or selective replacement of the corneal layers (e.g. Descemet’s membrane endothelial keratoplasty and deep anterior lamellar keratoplasty). Immunologic graft rejection is one of the main causes of graft failure in these corneal transplantations. The 2-year rejection rate …

3-D Homology Modeling Of Organic Anion Transporters (Oats): Defining The Biochemical Basis For Oat-Substrate Interactions, Christopher Jay

Theses and Dissertations

A goal in the drug development process, as indicated by the FDA, is to evaluate a drug’s ADME profile, as potential drug interactions could exist, leading to adverse drug reactions or loss of efficacy. Transport proteins, specifically organic anion transporters (OATs) are involved in the absorption, distribution, and elimination of small, negatively charged compounds. Although there is an exhaustive list of structurally diverse organic anions which interact with OATs, interactions at a molecular level are still shrouded in mystery particularly due to the lack of a solved crystal structure. Therefore, in silico homology models (hOAT1, 2, 3) were generated using …

Model-Based In-Vitro Pk/Pd Profiling Of Novel Synthetic Allosteric Effectors Of Hemoglobin (Aeh) As Potential Sickle Cell Disease (Scd) Therapeutics, Xiaomeng Xu

Theses and Dissertations

Introduction: Allosteric effectors of hemoglobin (AEH) represent a class of synthetic aromatic aldehydes that transiently form covalent interactions (Schiff-base) with hemoglobin (Hb) to form Hb-AEH adduct, preventing the HbS polymerization and sickling of red blood cells (RBC). The overall objective of this research was to aid in the optimization of novel AEH by understanding their target-site disposition of AEH in relevant biological matrices, e.g., HbA solution, whole blood (WB) and human liver cytosol (HLC), a surrogate of aldehyde dehydrogenase (ALDH)-mediated oxidative metabolism.

Methods: A “universal” HPLC-UV/Vis assay method was developed for the quantitation of HbA-AEH adduct for chemically …

Vaccine Hesitancy: Experimentalism As Regulatory Opportunity, Ana Santos Rutschman, Timothy L. Wiemken

All Faculty Scholarship

This symposium on patient innovation has prompted us to explore problems related to departures from official vaccination schedules. At a time in which vaccine confidence has been plummeting across the world, we argue that a more granular understanding—and ultimately a more finely tuned regulatory framework—is needed to reflect the current behavioral heterogeneity among indicated patients who choose to forego or delay administration of recommended vaccines. In particular, we focus on a phenomenon we term “vaccine staggering:” a departure from vaccination schedules in the form of delays in receiving one or more vaccines, which is motivated by the desire to boost …

Synthesis And Characterization Of Long Acting Darunavir Prodrugs, Mary Banoub

Theses & Dissertations

Patient adherence is critical for ART success to ensure adequate viral suppression, therefore, long-acting antiretrovirals are soon replacing current daily regimens. In recent years, two drugs were successfully transformed into long-acting injectables; CAB LA and RPV LA. These long-acting nanoformulations made it possible to abandon the daily pill burden, instead approximately a bimonthly injection of both drugs is enough to suppress and maintain viral load suppression. Our laboratory has been instrumental in transforming FDA-approved and experimental-HIV medications into long-acting slow effective release drugs, also known as LASER ART. LASER ART consists of slow drug metabolism and high permeability and retention …

The Development Of Hyaluronan-Based Contract Agents For The Intraoperative Detection Of Pancreatic Tumors, Bowen Qi

Theses & Dissertations

Pancreatic ductal adenocarcinoma is highly lethal and surgical resection is the only potential curative treatment for the disease. Tumor-specific intraoperative fluorescence imaging could improve staging and surgical resection, thereby improving prognosis. In the first study, hyaluronic acid derived NPs with physico-chemically entrapped indocyanine green, termed NanoICG, were utilized for intraoperative near infrared fluorescence detection of pancreatic cancer. NanoICG accumulated significantly in an orthotopic pancreatic ductal adenocarcinoma model with safety profile both in vitro and in vivo. To maximize tumor signal, while minimizing signal in healthy pancreas and RES capture of macromolecules, in the next study, we describe the rational …

Modified HA derivatives and CD44 biophysical interactions were assessed by fluorescence polarization. In silico techniques were also used to determine binding using molecular docking and MM-PBSA approaches. …

Theranostics For Antiretroviral Biodistribution And Pharmacokinetics, Brendan M. Ottemann

Theses & Dissertations

RATIONALE: Our laboratories birthed the field of human immunodeficiency virus (HIV) theranostics. The new field allows simultaneous detection (diagnostics) and treatment (therapeutic) for the identification, treatment and inevitable elimination of virus in cell and tissue compartments. By employing theranostics, antiretroviral drugs (ARVs) can be tracked in lymph nodes, gut, spleen and liver. Cellular viral reservoirs including CD4+ T cell populations and mononuclear phagocytes (MP; monocytes, macrophages, microglia and dendritic cells) along with subcellular endosomal structures can now be targeted for drug delivery bringing therapeutics to areas where virus replicates. The overarching idea rests in improving precision targeted ARV delivery. …
