The Rational Design, Synthesis, Characterization, And Biological Evaluation Of Cancer-Targeting Immunostimulatory Peptide-Protein Conjugates And Tripeptides, Keith Smith

Seton Hall University Dissertations and Theses (ETDs)

With the advent of cancer immunotherapy and the rise in applications of synthetic biologics, there has been a steady decline in the incidence of cancer. Despite this trend, there is an anticipated 1.7 million new cancer cases with an estimated 610,000 deaths expected by the end of 2018.2 Therefore, the call for continued efforts in creating more effective treatment options are still in high demand. In this thesis, the rational design of a semi-synthetic cancer-targeting immunostimulatory peptide-protein bioconjugate—using N-succinimidyl carbamate chemistry is described. This bio-orthogonal chemistry approach was used to conjugate the synthetic Pep42, cancer-targeting peptide (CTP) and the immunostimulatory …

Targeting Grp78 In Cancer With Nucleic Acid Bioconjugates, Pradeepkumar L. Patel

Seton Hall University Dissertations and Theses (ETDs)

Nucleic acid bioconjugates have gained widespread use in medicinal chemistry research programs aimed at fighting human malignancies such as cancer, diabetes, genetic and infectious diseases. Their popularity stems from their ability to accelerate the drug development process by conjugating chemical functionality that may improve the pharmacology of a bioactive nucleoside. Moreover, this strategy has been proven to be effective with small molecule nucleoside analogs and those derived from lengthy oligonucleotide sequences. Considering these fruitful applications, my research and this thesis aims to explore the synthesis, characterization and therapeutic potential of novel classes of nucleic acid bioconjugates.

These are based on, …

Poly(Arginine) Derived Cancer-Targeting Peptides For The Development Of A Cancer-Targeted Gene Therapy Approach In Hepg2 Liver Cancer Cells, Stesha C. Joseph

Seton Hall University Dissertations and Theses (ETDs)

Cancer is a disease that has eluded medicinal approaches for many years and as a result new and improved therapeutic approaches are in constant demand. Although chemotherapy and radiation treatments have assisted in suppressing the growth of tumors, their poor selectivity and efficacy are major limitations for effective therapy en route towards the development of a cure for the cancer epidemic. With the mission of conquering cancer at heart, researchers have pursued a new form of cancer therapy, aptly named, a cancer targeting approach. This method revolves around the selection of a suitable biomarker, typically a cell surface receptor …

Rna Interference Targeting Glucose-Regulated-Protein 78 Induces Hepg2 Cell Apoptosis, Brittany Blackman

Seton Hall University Dissertations and Theses (ETDs)

Cancer is a complex genetic disease that is driven by genetic mutations resulting in chronic, inappropriate cell proliferation. Many current cancer therapies lack specificity towards tumor tissues, ultimately leading to adverse side effects and limited clinical efficacy. Recently, selective cancer cell therapy has examined a well-characterized cell surface marker that is preferentially expressed on tumor cells. The over-expression of an endoplasmic reticulum chaperone protein, 78-kDa glucose-regulated-protein (GRP78), has been observed on the surface of cancer cells, but not on normal tissues. By selectively targeting GRP78 with short-interfering RNA (siRNA), potent GRP78 silencing is anticipated by the RNA interference (RNAi) pathway. …
