Cancer-Targeting Immunostimulatory Peptides As An Immunotherapeutic Approach To Cancer, Rachel Montel
Cancer-Targeting Immunostimulatory Peptides As An Immunotherapeutic Approach To Cancer, Rachel Montel
Seton Hall University Dissertations and Theses (ETDs)
This dissertation reports the synthesis and biological applications of bifunctional trimeric peptides with B7H6-derived NKp30 binding motifs that serve to activate an immunocytotoxic response in natural killer cells and a GRP78-binding motif that can target tumors that express surface GRP78. In this manner the cancer-targeting immunostimulatory peptides are anticipated to directly bind and activate effector NK92-MI cells while also recognizing and binding to target A549 tumor cells to facilitate NK cell-dependent immunocytotoxicity of the targeted tumors. The NKp30 binding peptide motifs are derived from the tumor associated B7H6 antigen that is often downregulated or shed from the surface of tumors …
Meta-Analysis To Identify And Evaluate Factors Associated With Regulatory Approval Of Orphan Drugs (Od) To Develop An Algorithm For Predicting Regulatory Approval (Success) And To Develop A Standardized Tool To Improve Orphan Drug Portfolio Decision-Making, Milky C. Florent
Seton Hall University Dissertations and Theses (ETDs)
Background and Purpose of the Study: Developed an algorithm (AODI) for predicting probability of regulatory success (PRS) for new orphan drugs after phase II testing has been conductedwith the objective of providing a tool to improve drug portfolio decision-making.Methods: Examined 132 studies from recent publications (2005 onwards). Data on safety, efficacy, operational, market, and company characteristics were obtained from public sources. Meta-analysis and meta-regressions were used to provide an unbiased approach to assess overall predictability and to identify the most important individual predictors.Results: Found that a simple three-factor model (disease prevalence, clinical trial duration and clinical trial …
Site-Selective Modification Of Peptides And Proteins Via Organocatalyzed Henry Reaction, Zilma Pereira Muneeswaran
Site-Selective Modification Of Peptides And Proteins Via Organocatalyzed Henry Reaction, Zilma Pereira Muneeswaran
Seton Hall University Dissertations and Theses (ETDs)
In this research, peptides and protein containing serine on the N-terminus underwent site-selective modification following organocatalyzed bioconjugation that offered an additional functional group. It was shown that transforming the N-terminus serine to an aldehyde allowed site-specific bioconjugation to occur by utilizing the well-known Henry reaction. This method also grants a safer pathway for bioconjugation utilizing “green-chemistry” and biocompatible conditions. Amino acids and amino acid derived organocatalysts were utilized in the Henry reaction resulting in yields of up to 86 % conversion. Promising preliminary results were achieved in this research using peptides and myoglobin as the bioconjugation targets. Further investigation to …
B7h6: A Cancer Biomarker For The Development Of Novel Immunotherapy Approaches, Mariana Phillips
B7h6: A Cancer Biomarker For The Development Of Novel Immunotherapy Approaches, Mariana Phillips
Seton Hall University Dissertations and Theses (ETDs)
Cancer-based immunotherapy has led the evolution of biologics that can stimulate immune responses towards tumor eradication. The synthesis of small to intermediate size molecules with the targeting and effector functions of mAb may represent a novel class of immunotherapeutics that may overcome the limitations of their biological counterparts.Towards this objective, B7H6 has been identified as a protein ligand localized on the cell surface of transformed tumor cells. B7H6 binds specifically to the activating receptor NKp30, constitutively expressed on all resting and active NK cells. Upon ligand:receptor binding, B7H6 triggers NK cell activation and release of chemokines and pro-inflammatory cytokines such …

Rnai Nanotechnology: A Platform For Sirna Screening And Cancer Gene Therapy, Mayurbhai Ravikant Patel
Seton Hall University Dissertations and Theses (ETDs)
Over the past two decades, advances in RNA structural biology have improved our understanding of the structures and folding properties of naturally occurring RNAs. RNA sequences and structures participate in many specific biological functions, such as those performed by messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), micro RNA (miRNA), short-interfering RNA (siRNA), small nuclear RNA (snRNA) and many others. The noncoding RNAs, such as siRNA, do not express proteins but have been utilized in a wide range of applications, including RNA interference (RNAi) and the regulation of mRNA expression. These important biological functions have been implemented in gene …
Preliminary Studies Into Dna Binding Capabilities Of Ruthenium Nitro Nitrosyl As Anti-Tumor Pro-Drugs, Natasha Hansson
Preliminary Studies Into Dna Binding Capabilities Of Ruthenium Nitro Nitrosyl As Anti-Tumor Pro-Drugs, Natasha Hansson
Seton Hall University Dissertations and Theses (ETDs)
The complex [Ru(bpy)z(NO)(N02)](PF6)2 was investigated as a potential anti tumor drug option. The nitrosyl group was displaced by reaction with azide ion in acetone to yield the solvento complex in situ. The products isolated from addition of a solution or slurry of guanine, adenine, cytosine or thiamine to the resulting [Ru(bpy)(N02)(acetone)t were investigated by electronic absorption spectroscopy, infra 1 red spectroscopy, H NMR spectroscopy and cyclic voltammetry. The results of the studies showed that guanine, adenine and thiamine form adducts with Ru(bpy)z(N02)(acetone)t. However, each base forms a unique complex as shown by electronic spectroscopy. Guanine is the strongest field ligand, …
