Smart hydrogel for enzyme responsive vaginal delivery of anti-HIV peptide therapeutics
(2021)
In response to an urgent need for advanced formulations for the delivery of anti-retrovirals, a stimuli sensitive hydrogel formulation that intravaginally delivers HIV-1 entry inhibitor upon being exposed to a specific ...
Metabolomics and chemical library screening for antibacterial drug discovery
(2020)
There are twenty standard amino acids which are proteinogenic and can exist in two stereoisomeric forms, D- and L-enantiomers, except for glycine, which is achiral. The D-amino acids are not incorporated in proteins; ...
Development of Closomer And MIBG based Nanoformulation: Application to HIV Prevention and Neuroblastoma Therapy
(2023)
This dissertation is divided into two parts. Part #1 focuses on the development and characterization of closomer based nanoformulation for the prevention of HIV/AIDS sexual transmission. Part #2 focuses on the development ...
Enhanced Etoposide Solubility and Anticancer Activity using Complexation and Nanotechnology
(2021)
Etoposide is a first line treatment for different cancer types that can be used either alone or in combination with other therapeutic agents. However, systemic toxicity, variable oral bioavailability, and high drug resistance ...
Development and Evaluation of 3D-Printed Cardiovascular Stents
(2022)
for HEMA and HEMA-0.35MeGO after 21 days. 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay revealed that 3D stents loaded with RSL (~1 mM) exerted no cytotoxic effects on the human umbilical vein...
Development of Amino Acid-Modified Drug Delivery Systems for RNA Delivery in Cancer Therapeutics
(2022)
The primary objective of my research is to develop polymer and lipid-based nanoparticles to effectively deliver therapeutic RNAs for life-threatening diseases. Small interfering RNAs (siRNAs) and messenger RNAs (mRNAs) are ...
Library Screening and Focused Multiomics of Antibacterial Action on Vancomycin-Resistant Enterococci faecium
(2023)
Antimicrobial resistance is a major public health threat, and there is an urgent need for new strategies to address this issue. In a gram-positive bacteria, the peptidoglycan layer is thick as compared to gram negatives ...
Development of Nanomedicine to Simultaneously Target Pancreatic Cancer Cells and Stroma
(2020)
Dense desmoplastic stroma is a fundamental characteristic of pancreatic ductal adenocarcinoma (PDAC) and comprises up to 80% of the tumor mass, which acts as a barrier that impedes the delivery of antitumor drugs into the ...
Cell wall metabolite levels as a function of the growth phase in Staphylococcus aureus and library screening for synergistic combinations of FDA approved drugs against methicillin resistant S. aureus
(2022)
Liquid chromatography-tandem mass spectrometry (LC-MS/MS) based methods for quantifying cell wall biosynthesis intermediates. These include LC-MS/MS methods for quantifying cytoplasmic UDP-linked peptidoglycan biosynthesis ...
Novel nanocarriers to improve drug delivery for age-related macular degeneration
(2021)
Visual impairment affecting the posterior segment of the eye is a significant health problem causing a deterioration of the quality of life of millions worldwide. Age-related macular degeneration (AMD) is ranked third on ...
Discovery and Delivery of Peptide-Based Immune Checkpoint Inhibitors Targeting Pd-L1 for Cancer Immunotherapy
(2022)
The objective of this dissertation is to develop peptide-based immune checkpoint inhibitors that block the interaction between programmed cell death ligand-1 (PD-L1) and its receptor programmed cell death protein 1 (PD-1) ...
Topical Clear Aqueous Nanomicellar Formulations for Age-Related Macular Degeneration
(2020)
Disorders affecting the posterior segment of eyes represent a significant burden to healthcare and patients’ wellbeing. Among the back of the eye disorders, age-related macular degeneration (AMD) is one of the major ailments ...
