Exploring The Design Space Of Antifungal Peptides, Miryam Kikhwa
Exploring The Design Space Of Antifungal Peptides, Miryam Kikhwa
Seton Hall University Dissertations and Theses (ETDs)
The synthesis, characterization, and evaluation of antifungal activity of peptides FQ15 and FG10 will be conducted to address the hypothesis. The hypothesis of this thesis is that a peptide with similar properties to AS15 would have similar activity against Cryptococcus neoformans. This study addresses the challenge of drug- resistant microbes by developing inhibitors targeting lipid flippase and exploring their potential as antimicrobial agents against Cryptococcus neoformans. Chapter 1 provides a historical context of the background on the development of antimicrobials and common antifungal treatments, as well as an introduction about C. neoformans and its resistance mechanism. Chapter 2 introduces the …

Osteoblast-targeting peptides in the treatment of bone disease is a new and novel approach to offering effective treatment of various cancers and can be used in bio-medical, medicinal chemistry and biotechnology applications. By targeting adhesion proteins produced by osteoblast cells, certain cancers which migrate and metastasize to the bone may be more effectively treated. An osteoblast-targeting peptide composed of Ser-Asp-Ser-Ser-Asp (SDSSD) which selectively binds to osteoblast cells via periostin has recently been identified. This peptide was functionalized with polyurethane, generating nanomicelles which encapsulated RNA for the therapeutic treatment of osteoporosis. This study has served as the basis for the research …
Flippase Inhibitors As Antimicrobial Agents, Robert Tancer
Flippase Inhibitors As Antimicrobial Agents, Robert Tancer
Seton Hall University Dissertations and Theses (ETDs)
Drug resistant microbes are a considerable challenge for modern medicine to overcome. The research described in this dissertation involved development of lipid flippase inhibitors and investigating their potential as antimicrobial agents against various drug resistant microbes. The microbes primarily investigated were methicillin resistant Staphylococcus aureus (MRSA) & Cryptococcus neoformans. Chapter 1 reviews the historical perspective and summarizes the current state of the field of research. In Chapter 2, the design space of an antimicrobial peptide known as humimycin was explored and the effects of modifications on its structure were observed against MRSA. Several key observations resulted. Most notably, the …
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 …

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 …
