Amphiphilic Cell-Penetrating Hybrid Cyclic-Linear Peptides As A Drug Delivery System, Saghar Mozaffari

Pharmaceutical Sciences (PhD) Dissertations

A number of cyclic peptides containing a positively charged ring composed of arginine residues attached to hydrophobic tail made of tryptophan residues through a lysine linker namely [R₅K]W₅, [R₆K]W₅, [R₅K]W₆, [R₇K]W₅, [R₅K]W₇, [R₆K]W₆, and [R₇K]W₇ were synthesized and evaluated as molecular transporters. The peptides were evaluated for their ability to deliver, fluorescence-labeled cell-impermeable negatively charged phosphopeptide (F′-GpYEEI), and fluorescent labeled anti-HIV drugs (F′-FTC and F′-d4T). The results indicated that the presence of positively …

Synthesis Of Gadolinium-Doxorubicin Prodrug Carrying Functional Nanoceria For The Targeted Drug Delivery And Cancer Treatment, Arth Patel

Electronic Theses & Dissertations

The main focus of this research was the development of a polymer-coated nanoceria (PNC) platform to be used as a drug delivery system. Water-dispersible PNC is synthesized using a water-based alkaline precipitation method. Cerium nitrate hexahydrate and poly (acrylic acid) are used for the preparation of PNC. The synthesized PNC was characterized using ZETA, and UV- Vis characterization techniques. Polyacrylic acid (PAA)-coated cerium oxide nanoparticles fabricated for the targeted combination therapy of TNBC (MDA-MB-231) and MCF-7. Using EDC/NHS chemistry, the surface carboxylic acid groups of nanoceria was designed and synthesized with ICAM-1 antibody to target ICAM-1 overexpressing TNBC. Next, doxorubicin …

Development And Evaluation Of A Cancer Registry For Shirdi Sai Baba Cancer Hospital And Research Centre, Kanav Khera Dr

Manipal College of Pharmaceutical Sciences, Manipal Theses and Dissertations

Background: There exists a National Cancer Registry Programme (NCRP) aimed at collecting cancer patient data at the hospital and population level. 33 population-based cancer registries (PBCRs) and 100+ hospital-based registries (HBCRs) are present. Continuous training of professionals and monitoring of data completeness are a requisite to ensure generation of reliable databases. Advances in information technology allow for proper planning and development in all active registries. However, due to lack of time and personnel, systematic filling in of data takes a back-seat in India. Objectives: To develop a cancer registry for Shirdi Sai Baba Cancer Hospital and Research Centre. Methods: After …

Car T Cells As A Patentable Therapeutic, Mckenzie List

Honors Program Theses

The development of a therapeutic to treat a particular disease is a complicated process that incorporates numerous components such as drug discovery, clinical trials, FDA approval and patentability. In the last two decades, cancer research and development has shifted from identifying small molecule therapeutic agents to focusing research on a novel approach designated as immunotherapy. Today, immunotherapy has progressed from a twentieth century scientific theory into an innovative treatment to cancer. In particular, CAR T cells have demonstrated therapeutic properties for certain types of cancers, but these living cells are not compatible with the traditional therapeutic model. First, the drug …

Semisynthetic Aurones: A Family Of Newly Discovered Tubulin Inhibitors As Antineoplastic Agents, Yanqi Xie

Theses and Dissertations--Molecular and Cellular Biochemistry

Aurones belong to an uncommon class of plant flavonoids that provide the bright yellow coloration of some ornamental flowers and that possess a range of biological activities. Structure-activity relationships (SAR) in the aurone pharmacophore identified heterocyclic variants of the (Z)-2-benzylidene-6-hydroxybenzofuran-3(2H)-one scaffold that possessed low nanomolar in vitro potency in cell proliferation assays using various cancer cell lines, in vivo potency in prostate cancer PC-3 xenograft and zebrafish models, selectivity for the colchicine-binding site on tubulin, and absence of appreciable toxicity. Among the biologically active analogs developed in the course of this dissertation work were (Z …

Towards The Rational Design And Application Of Polymers For Gene Therapy: Internalization And Intracellular Fate, Landon Alexander Mott

Theses and Dissertations--Chemical and Materials Engineering

Gene therapy is an approach for the treatment of acquired cancers, infectious disease, degenerative disease, and inherited genetic indications. Developments in the fields of immunotherapies and CRISPR/Cas9 genome editing are revitalizing the efforts to move gene therapy to the forefront of modern medicine. However, slow progress and poor clinical outcomes have plagued the field due to regulatory and safety concerns associated with the flagship delivery vector, the recombinant virus. Immunogenicity and poor transduction in certain cell types severely limits the utility of viruses as a delivery agent of nucleic acids. As a result, significant efforts are being made to develop …

The Development Of Novel Proteasome Inhibitors For The Treatment Of Multiple Myeloma And Alzheimer’S Disease, Min Jae Lee

Theses and Dissertations--Pharmacy

Over a decade, proteasome inhibitors (PIs), bortezomib, carfilzomib (Cfz) and ixazomib, have contributed to a significant improvement in the overall survival for multiple myeloma (MM) patients. However, the response rate of PI was fairly low, leaving a huge gap in MM patient care. Given this, mechanistic understanding of PI resistance is crucial towards developing new therapeutic strategies for refractory/relapsed MM patients.

In this dissertation work, we found H727 human bronchial carcinoid cells are inherently resistant to Cfz, yet susceptible to other PIs and inhibitors targeting upstream components of the ubiquitin-proteasome system (UPS). It indicated H727 cells may serve as a …
