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, …

Submonomer Synthesis And Structure-Activity Relationship Studies Of Azapeptide Inhibitors Of The Insulin Receptor Tyrosine Kinase, Lathamol A. Kurian

Seton Hall University Dissertations and Theses (ETDs)

Azapeptides are a class of peptide mimics (peptidomimetics), which have served as valuable tools for the development of peptide based therapeutic agents. The therapeutic promise of azapeptides has been correlated to its primary sequence modification which translates into bio-active secondary structures that improves the pharmacological properties of the native peptide sequence. More specifically, azapeptides contain a semicarbazide within the peptide backbone which restricts the peptide bond torsion angles (φ, ψ) into pre-organized b-turn secondary structures. Thus, azapeptides have been shown to stabilize bio-active b-turn secondary structures responsible for high affinity and selective binding to a target …

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 …

Branching Into Rnai: Synthesis, Characterization And Biology Of Branch And Hyperbranch Sirnas, Anthony Muriithi Maina

Seton Hall University Dissertations and Theses (ETDs)

The cancer epidemic continues to afflict millions of humans world-wide each year and despite a renewed hope with the development of new and improved forms of therapy, a cure for cancer remains an elusive goal. This is partly related to the rise of resilient forms of tumors that have evolved with resistance towards conventional chemotherapy and radiation treatments. Moreover, these non-specific therapeutic regimens are highly toxic, leading to severe immunosuppressive effects which poisons the body and compromises the road towards remission. In an effort to mitigate these limitations, cancer-targeting approaches are currently experiencing a renaissance in the translation of new …

Porphyrin Cross-Linkers For Generating Soluble Molecularly Imprinted Polymers From Polyethyleneimine, Mohammed R. Elshaer

Seton Hall University Dissertations and Theses (ETDs)

Molecular recognition is vital to many biochemical processes and is at the heart of promising bio-medically related technologies. Molecular imprinting has a long-standing history as a successful method for mimicking the molecular recognition phenomena exhibited by nature, whereby artificial receptors are prepared for a given target molecule based on synthetic polymers. The molecularly imprinted polymer (MIP) contains a three dimensional network with a memorized cavity specific to the shape and functionality of the templated target molecule. The utility of traditional MIPs has been limited due to an inherent lack of solubility. We have worked toward developing a system that allows …
