Computer-Aided Drug Design And Discovery, Screening And Synthesis Of Small Molecule Inhibitors Of Nucleoside Transporters, Hilaire Colleen Playa

Theses and Dissertations (ETD)

Using prior biological data, pharmacophore models were made for hCNT1, hCNT3, hENT1, and hENT4. The hCNT3 and hCNT1 pharmacophore were used to select compounds for biological testing. The NBMPR analogue and dipyridamole analogue hENT1 pharmacophores were compared to each other and to a combined pharmacophore for hENT1. The dipyridamole analogue pharmacophore better predicted non-nucleoside small molecule inhibitors, and as such appears to be the better tool for aiding in the design of new small molecule inhibitors. The hCNT3 pharmacophore failed to select active compounds and as such must be redesigned. The hCNT1 pharmacophore succeeded in identifying two moderately active compounds …

Nucleoside reverse transcriptase inhibitors (NRTIs) are mainstay therapeutics for HIV that block retrovirus replication. Alu (an endogenous retroelement that also requires reverse transcriptase for its life cycle)–derived RNAs activate P2X7 and the NLRP3 inflammasome to cause cell death of the retinal pigment epithelium in geographic atrophy, a type of age-related macular degeneration. We found that NRTIs inhibit P2X7-mediated NLRP3 inflammasome activation independent of reverse transcriptase inhibition. Multiple approved and clinically relevant NRTIs prevented caspase-1 activation, the effector of the NLRP3 inflammasome, induced by Alu RNA. NRTIs were efficacious in mouse models of geographic atrophy, choroidal neovascularization, graft-versus-host disease, and sterile …

Inhibition Of The Thioesterase Activity Of Human Fatty Acid Synthase By 1,4- And 9,10-Diones, Herman H. Odens

Faculty Works

Fatty acid synthase (FASN) is the enzyme that synthesizes fatty acids de novo in human cells. Although FASN is generally expressed at low levels in most normal tissues, its expression is highly upregulated in many cancers. Consistent with this notion, inhibition of FASN activity has demonstrated potential to halt proliferation and induce cell death in vitro and to block tumor growth in vivo. Consequently, FASN is widely recognized as a valuable therapeutic target. In this report, we describe a variety of 1,4-quinones and 9,10- anthraquinones, including several natural compounds and some newly synthesized compounds, that potently inhibit the thioesterase (TE) …

Effect Of Twin Screw Granulator Process Parameters On Granule Attributes, Haosheng Xu, Ridade Sayin, James Litster

The Summer Undergraduate Research Fellowship (SURF) Symposium

Twin screw wet granulation has been considered as an efficient and effective technique of manufacturing granules (agglomerates made up of small particles) and has been widely applied in pharmaceutical industry. However, narrow granule size distributions are difficult to achieve. This study aims to elucidate the effect of process parameters such as liquid feed rate and screw configuration on the granule attributes through granule characterization. The methods used are sieve analysis (for size distribution), liquid distribution (determining the dye concentration in the granules) and density and porosity (percentage gas volume in the granule) analyses. A sieve shaker is used to divide …

Hydrodynamic Cfd Modeling Of A Pharmaceutical Reactor Vessel Provided With A Retreat-Blade Impeller Under Different Baffling Conditions, Christopher G. Foehner

Theses

In the pharmaceutical industry, glass-lined reactors and vessels are often utilized to carry out a variety of different unit operations. Within these systems, both the vessel and impellers are typically glass-lined in order to provide superior corrosion resistance, prevent product contamination, and enhance cleanability. This approach, in turn, often requires the use of different, and sometimes sub-optimal, baffling conditions, which affect the hydrodynamics of the vessels and the reactor performance.

Computational Fluid Dynamics (CFD) is a computational tool that employs numerical methods and algorithms to discretize and numerically solve partial differential equations (PDEs) representing mass, energy, and momentum conservation equations …

Assessment Of A Marine Polysaccharide For Use As Excipient In Pharmaceutical Hot-Melt Extrusion, Qing Ye

Theses

Pharmaceutical Hot Melt Extrusion (HME) is currently investigated by both industry and academia as a method for manufacturing solid oral dosages with improved bioavailability of poorly-water soluble active pharmaceutical ingredients (APIs) and control drug release of water-soluble APIs. Although HME is traditionally utilizing synthetic polymers to produce such dosages, biopolymers constantly gain ground by virtue of renewability, biocompatibility and in some cases biodegradability. In this work, the possibility of using Keltone, a marine polysaccharide derived from brown seaweed, as a polymeric excipient for pharmaceutical HME is explored. Keltone is insoluble in acidic pH and soluble in basic pH, therefore making …

Dispersion And Dissolution Kinetics Of Api Particles In Pharmaceutical Hot Melt Extrusion, Wang Zhan

Theses

Pharmaceutical Hot Melt Extrusion (HME) is essentially a special case of polymer compounding. The elementary steps involved in traditional plastics melt processing are handling of particulates, melting, dispersive and distributive mixing, devolatilization and stripping, and finally pressurization and pumping. However, for pharmaceutical HME, the dissolution of the API (Active Pharmaceutical Ingredient) is an additional and very important elementary step, along with the melting of the polymeric excipient that precedes it, and mixing which accelerates the dissolution process. A major concern in pharmaceutical HME is the thermal degradation of the API. To avoid overexposure of API to heat while ensuring complete …

Experimental Determination Of The Mixing Requirements For Solid Suspension In Pharmaceutical Stirred Tank Reactors, Anqi Zhou

Theses

Glass and glass-lined, stirred-tank reactors are of significant importance in the pharmaceutical and related industries. Because of fabrication issues, a retreat blade impeller (RBI) with a low impeller clearance off the tank bottom is commonly used in glass-lined reactors, typically combined with a single baffle (providing only partial baffling conditions) mounted from the top of the reactor. In addition, these reactors are often provided with a torispherical bottom. Other configurations are also used, including full baffling or no baffles at all, hemispherical bottoms, and different impeller types. Despite their common use, some of the most important mixing characteristics of this …

Nanotoxicity In Cells Of The Immune System, Jonathan J. Pelc

Science Scholars

Nanoparticles (NPs) provide a new medical approach to drug therapy. As with every new approach, safety precautions need to be taken, and the immediate and long-term effects for many NPs are still unclear. When administering a medical treatment into the human body, the first issue that needs to be addressed is host detection of the medicine and inflammation as a possible result of the treatment. If a new NP treatment causes inflammation before it releases its medicine, that treatment may be ineffective, even damaging to the patient. Small metallic and organic particles have been shown to elicit an inflammatory responses …

Glioma: A Tale Of Corticosteroids, Thiopurines And Proposed Novel Antiglioma Small Molecules, Amira Ahmed

Theses and Dissertations (ETD)

Glioma is a brain tumor that arises from glial cells or glial progenitor cells, and represents 80% of malignant brain tumor incidence in the United States. Glioblastoma multiforme (GBM) is the most aggressive primary brain tumor malignancy with fewer than 8% of patients with GBM surviving for 3 years. Over the past 10 years, despite improvement in diagnosis and therapies for cancer, the survival rate for high-grade glioma patients remains unchanged.
